ITTF Cadet Camp at MDTTC
The ITTF, in conjunction with USA Table Tennis and the Canadian TTA, ran a four-day ITTF Cadet Camp at the Maryland Table Tennis Center over Labor Day Weekend, Fri-Mon. Fifteen players took part in the camp, including five USA national team members: Crystal Wang (Junior and Cadet Girls); Derek Nie and Klaus Wood (Cadet Boys); and Lisa Lin and Faith Hu (Mini-Cadet Girls). Also taking part were Ivy Liao and Isabelle Xiong, members of the Canadian Women’s, Junior, and Cadet Girls’ Teams. The camp had nine sessions, 22 hours total. Here’s a group picture.

Wang Qing Liang (“Leon”), recently named a USA National Cadet Coach, was the head coach, and planned out and ran much of the camp. Other coaches were Cory Eider (USATT High Performance Director), Liu Yongjiang (Canadian National Cadet Coach), and myself (a USATT certified National Coach and former USA Junior Team Coach). Wen Hsu was the Camp Coordinator. Practice partners were Nathan & John Hsu, Heather Wang, You Lyu, and Yan Zhang. (Practice partner and coach is almost interchangeable as the practice partners were also coaching and often feeding multiball.)

If I listed every drill done during the camp, this would be a long blog. Let’s just say the focus was on footwork, serve & attack, and serve & receive. At the start of the camp, the drills were a bit more generic as they did drills where they had to cover a lot of ground very fast (i.e. footwork). More and more the drills became more game like, often starting with a serve and loop. There was a lot of service practice, generally followed by receive practice, with lots of flipping and short receive. One of my favorite drills is when the coaches fed multiball half-long backspin, and the players had to judge whether the ball was long enough to loop, or had to push or flip. As a feeder, I had fun trying to mess them up by feeding balls right in between! (It also inspired this morning’s Tip of the Week, Looping Slightly Long Balls.)

Physical training was a major component of the camp. Most sessions started with jogging and various side-stepping routines. Twice they did ladder drills, where they work on speed and foot coordination. Twice they did “plank” training. They also did the “hill runs” – there’s a steep hill just outside the club, and we made use of it. The kids had to run up the hills, jog back, and repeat about ten times. Then they repeated this running backwards. And finally they did it on their hands and feet – no knees or other part of the body touching the ground – and had to go up the hills this way backwards, feet first. It was torture great fun!!!

Several times in the camp they played matches, including a practice tournament, a team competition, and doubles. After each, the players were required to write out why they won or lost. You don’t learn from these things if you can’t do that. At the end of the camp Cory emphasized to the players how important tournament competition is – many of them are only playing 6-8 tournaments per year when they should be playing more like 20. The best juniors generally play lots and lots of tournaments, and it is this constant feedback – plus the incentive to train for these tournaments – that leads to much improvement. I pointed out that I’d heard coaches argue that one tournament is worth one or two weeks of training. I also pointed out that lots of tournaments is the cure for those who are afraid of losing rating – you both get used to playing lots of rated matches and so lose the fear of it, plus you know you have another tournament coming up in  a week or so anyway, so your current rating is mostly meaningless.

Here is the lighter side of the camp:

  • Amy Wang (USA Junior and Cadet Girls’ Team) was supposed to participate, but had to go to a separate ITTF event. But when we arrived, some of us thought she was there – and throughout the camp people kept thinking they saw her because Canadian Isabelle Xiong looks almost exactly like her! (They even play similarly.) I’m looking forward to seeing them side by side. If I hadn’t been told Amy wasn’t coming, I would have gone over to Isabelle and said, “Hi Amy!”
  • I bought four mini-paddles at the USA Nationals, but they had cheap sponge on them, and weren’t fun to play with for many. So I put Tenergy on both sides on two of them – and the kids went crazy with them! They took turns throughout the camp during breaks, and put on quite a counterlooping and lobbing show with them.
  • During break, Klaus Wood practiced various around-the-net sliding shots – and here’s the video montage (30 sec) of these shots in slow motion – they are pretty spectacular!

I’d like to thank all those who made the camp possible – ITTF, USATT, CTTA, MDTTC, Cory Eider, the players and coaches, and MDTTC’s tireless worker Wen Hsu. Without them these poor kids would have spent another Labor Day Weekend watching TV while their overseas counterparts were sweating and improving.

The 2016 U.S. Presidential Race Cartoon – Revisited
On Friday I posted my 2016 Presidential Race Cartoon, which I hope you enjoyed. The cartoon was made up of 77 distinct images, combined in Photoshop. (I still have the version with 77 layers, one for each item, so I can edit them individually.) Up until the last minute I was toying with sticking in something about Trump’s hair, but things were a bit jammed, and let’s face it, that would be too easy. (I was thinking about making his hair a tribble from Star Trek.) I also toyed with giving him a “Make America Great Again” baseball cap, with an asterisk that said something like, “You realize I’m saying America isn’t great?” For Clinton, I toyed with putting some bulge on her back, due to the conspiracy theories about that being a defibrillator vest. But I’m guessing most readers haven’t heard about that one.

The original background images was Oh Sang Eun vs. Timo Boll. I chose the picture because I needed one where both players and the audience could clearly be seen. However, Oh is just standing there, so I removed him and replaced him with this one of Fan Zhendong. Then I removed the umpire, cleaned up the image, and put in all the other images.

Hopefully, most readers could recognize the people in the audience, but here they are, L-R, starting with the “Trump Cheering Section”: Russian President Putin, NJ governor Chris Christie (what was he thinking???), the Joker (from “The Dark Knight”), Dennis Rodman, Charlie Sheen, Sarah Palin, Mike Tyson, and the three KKK’s. (Rodman, Sheen, Palin, and Tyson are all publicly for Trump.) The two “Poorly Educated White Guys” are generic pictures of rednecks, and the five in the “New Jersey Muslims Jumping Up and Down Celebrating 911” are also generic pictures. Next to the aisle and saying, “We want to play” are the Libertarian and Green Party candidates, Gary Johnson and Jill Stein. To their right, in the “Clinton Cheering Section,” are Presidents Bush Sr., Obama, Bush Jr., B. Clinton, and Carter.

Revelations of a Table Tennis Champion
Our My long two-week national personal nightmare work binge is over!!! The book, “Revelations of a Table Tennis Champion” (the autobiography of Dan Seemiller) is edited, proofed, the photos fixed up, the pages laid out, and it’s all done! It came in at 214 pages with 94 pictures, divided into eleven chapters.  Book should be available around Sept. 15.

Unfortunately, it’s not actually done. This morning at about 1AM I sent the interior proofs to Dan Seemiller for him to proof. He’ll likely have changes. (Since I wrote this there have already been two changes.) Plus I haven’t finished with the front and back covers. Plus I have to decide whether it’s worth spending roughly seven hours to create an index. Anyway, today I will try to finalize the covers. Fortunately…

Flu Status
Our My long three-day national personal nightmare illness is over!!! It’s been fun exploring the many symptoms of the flu - I won’t go into that here other than to say that you have never had pain like the pain from flu-induced joint pain. I’m still pretty tired; I feel like I just ran a marathon. But I’m mostly over it just in time for…

ITTF Cadet Camp
It starts tomorrow. A bunch of top juniors – ages 10 to 15 – will be training Sept. 2-5 (Fri-Mon) at the ITTF Cadet Camp at the Maryland Table Tennis Center. Coaches are USATT High Performance Director Cory Eider, Wang Qing Liang, Han Xiao, Canadian Coach Liu Yongjiang, and myself. Players attending include Crystal Wang, Derek Nie, Klaus Wood, Jayden Zhou, Lisa Lin, and Faith Hu, all members of the various USA National Cadet or Mini-Cadet Teams, plus a number of others. There’ll be two table tennis sessions each day (2-3 hours each), plus 90-minute physical training sessions on Sat and Sun.

Windshield Wiper Serve
Here’s the coaching video (2:59) from PingSkills. This is one of my favorite serve variations – I’ll throw it at someone when I need a “free” point. (As mentioned in the video, it’s not a common serve, so players aren’t used to it.) Ricky Seemiller used to do this serve better than anyone. The main weakness of the serve is it’s difficult to get great backspin, though an expert such as Ricky was able to do this. You can get great sidespin with this serve. I disagree with the video where it says you get less spin with this serve than with the pendulum serve – I actually get more with this serve, and Ricky used to have the spinniest serves in the world with this. The wrist really snaps into this serve with a very natural super-spinny sidespin.

Still Sick
I’m writing this at 4:45AM. Why? Because I’m in all sorts of joint pain from the flu, especially hip pain, and I can’t sleep. Most of the flu symptoms aren’t as bad as the last time I had the flu (though my stomach can best be described as “hyper-queasy”), but the joint pain is incredible. This happened yesterday as well – it seems to act up more at night. It’s very painful to lie down; sitting or standing is the only way to alleviate it. Anyway, the good news is that most of yesterday it wasn’t so bad, so I got a lot of work done on Dan Seemiller’s autobiography – in fact, other than the index and finalizing the covers, it’s basically ready to print out and proof. I’m hoping to do that today, flu gods permitting.

Big Breaking Sidespin Serve
Here’s the video (4:30), but the link should take you to 26 sec in, where the kid on the far side does the breaking serve. I do this serve all the time, and I’ll never understand why more players don’t learn such serves. It’s just a matter of serving deep with a lot of sidespin. Not only does it work here when you serve into an opponent’s forehand (lefty serving to righty or vice versa), but it also works if you serve it into the backhand (righty vs. righty or lefty vs. lefty), where it breaks away from the player, forcing them to reach for the ball.

I'm sick in bed with a cold, so no blog today. I desperately need to get over this quickly so I'll be ready for the ITTF Cadet Camp at MDTTC this Frida-Mon. I also need to drag myself out of bed later today to continue the page layouts on Dan Seemiller's great new autobiography, "Revelations of a Table Tennis Champion." If I put in a full day, I'd finish the layouts today, other than the index and final proofing. (Dan - I know you're reading this! - I hope to finish tomorrow.) Meanwhile, here's a picture of a solid gold ping pong table in Dubai! 

UPDATE: It looks like I have the flu. And I was planning to get a flu shot last week, then put it off until this week....

Tip of the Week
Keep a Notebook.

How to Stay in Practice Without Practicing
A student told me over the weekend how he’d taken two weeks off for vacation, and when he came back, he couldn’t play at all. He said it took about five sessions before he could play comfortably again. He also said the same thing happens when he takes time off from his other sport, basketball. Yet, he said he knew others who seem to be able to take time off from these sports and come back very quickly. “Why?” he wondered.

Now I’ve never done a study of this, which is why this not yet ready to be a Tip of the Week, but I’ve noticed something very obvious about this. When I asked the player if he’d spent much time thinking or visualizing table tennis during his two weeks away, he said no. I think that players who take time off but spend some of that time visualizing playing (in their head), and maybe even shadow practicing it some, come back more quickly. Your game is controlled by your subconscious, and so any thinking about your shots re-enforces that muscle memory.

So next time you go on vacation or are injured, spend some time each day visualizing in your head playing a match. Really play it out! Serve and attack, receive, block, loop, counterloop, smash, lob, chop – whatever you do in a game, do it in your head. And I bet when you come back, you’ll get right back into it very quickly.

Coaching During a Game, Part 2
I blogged about this last Friday, where I explained why I'm opposed to the rule - and gave 14 different reasons. Bottom line - I think the ITTF has made a dumb mistake here, and I expect the rule will eventually be rescinded. When? I don't know; maybe in a year, maybe ten, maybe never. The rule takes effect on Oct. 1. 

But now we have to make a separate decision, one that requires nuanced thinking. Given that the rule is not a good one, should USATT adopt it? At first, the obvious thought is "Heck no!" (Ah, a G-rated column blog....) Why in the world should USATT adopt a rule we consider bad? Even the USATT Umpires and Officials Committee has come out and voted unanimously that we should not adopt this rule. 

But here's the problem. Even if we don't adopt it, it will still be the rule at ITTF tournaments. That means the U.S. Open; continental Olympic and Pan Am Trials; overseas tournaments that our players go to; and I believe the North American Teams. If USATT does not adopt the rule, then what happens to our players and coaches at these events? They'll be at a terrible disadvantage. While opponents will have had lots of time to develop signals and other ways to communicate with their coaches without opponents being able to read them, and coaches and players will be used to this new style of non-stop coaching (like a cornerman in a boxing match screaming non-stop instructions), our players and coaches won't. 

It's going to take a lot of getting used to, and the methods used for communication will continually evolve, as I wrote about last week. We'll be way, way behind. USATT coaches like myself are going to be very uncomfortable - and less effective - when we go up against coaches who are used to this rule. We'll be like someone from organized boxing in a street fight where there are no rules. We'll be bringing a hardbat to a sponge battle. 

So the question is - should USATT adopt this rule? We have to decide soon. I'm on the USATT board, which has its next meeting in Philadelphia on Oct. 10, the day after the Women's World Cup. Because that's after the Oct. 1 date that the rule comes into effect, the USATT board may have a teleconference call on this before that. I've already asked for input from the USATT Rules Committee, and would also do so from the USATT Coaching Committee except it currently (and temporarily, I hope) has no chair. This is a hugely important issue that is not to be taken lightly. 

I am quite frankly undecided about this one. I'm leaning - slightly - toward adopting it, for the reasons given above - we're going to have to deal with it anyway, and I'm a bit leery of the affect it'll have on our national teams. (Men; women; paralympic men and women; and junior, cadet, and mini-cadet boys and girls - that's at least ten teams right there.) At the same time, I loathe adopting what I consider a dumb rule. 

So . . . anyone want to chime in on this one?

On a side note, some will notice the similarity here with the illegal hidden serves that are allowed by umpires and referees worldwide, with both ITTF and USATT reluctant to step in and stop all the rampant cheating that takes place right in front of us. Because it's mostly allowed internationally, many believe USATT should just accept this cheating as part of the game, while others (including me) do not believe we should do so. There are similarities, but there are two big differences.

First, illegally hiding a serve is illegal, while legally giving coaching under the new ITTF rule is legal.

Second, even players who regularly use illegal serves - nearly all top players have to if they want to compete successfully - have to have legal serves as well, in case their illegal serves are called. So even though I've argued that USATT should take the lead in cracking down on illegal serves (i.e. cheating), I've also argued that our players should learn illegal serves as well, but use them only when the umpire allows the opponent to do so, i.e. the game is no longer being played by the rules, and serving illegal, like the opponent, no longer is giving an unfair advantage. It's an unfortunate situation that our culture of cheating has created, and it forces players to develop their service games around both legal and illegal serves, but that's the situation we have until ITTF and/or USATT leaders take action and lead. (I tried – Motion 6 - but was voted down.) But that's a separate issue - back to the new coaching rule.

How Many Ping-Pong Balls Can Fit in a Table Tennis Club?
Today's topic is scary. We're talking something that will leave many readers shaking with fear, sweating like David Sakai, and plucking their eyeballs out as they scream, "No! For God's sake, Stop!" Yes, today we're going to use math. (You have my permission to skip the math part and just read the paragraphs that give conclusions.)

How many ping-pong balls can you fit in your table tennis club? It's a simple matter of working out volume with the sphere packing formula. As we all know (after reading the Wikipedia entry I just linked to), as volume goes up and the size of the balls (sphere) goes down, the packing efficiency approaches the following density, which I'll call the Packing constant (P). (Hopefully, in my formulas below, the subscripts and superscripts will come through properly on your browser.) 

P = π/[3x(2)^½] = ~0.74048

So how can we use this?

  • Let Nd = number of balls of width d that will fit in your club.
  • Let C = volume in cubic inches of your club.
  • Let B = volume of the balls in cubic inches.

Then the number of spheres (N) you can fit inside a given volume approaches the following:

Nd = (C/B)xP = maximum number of spheres you can fit inside your club.

To get C, you simply get the volume in cubic inches of your club. This is easy if it is roughly rectangular shaped. (We're using inches and feet here, since I live in archaic America, which hasn't adopted the metric system.) Multiply your club's dimensions in feet – length x width x height – and then multiply by 1728 (number of cubic inches in a cubic foot) to get cubic inches for your club.

B is the volume of the ball in cubic inches. Since volume of a sphere is 4/3 πr^3, we simply plug in the radius of a ping-pong ball, which is half the 40mm diameter or 20mm, or roughly 0.7874". Plugging this into the volume formula, we get B = ~2.045 cubic inches.

So to get the number of 40mm ping-pong balls that will fit in your club, here's the formula:

N40 = (C/2.045) x 0.74048 = C x 0.3621

So to get the number of ping-pong balls that will fit in your club, you get the volume in cubic feet, multiply by 1728 to convert to cubic inches, and multiply by 0.3621 – and presto, there's your answer!!!

For my club, Maryland Table Tennis Center, the dimensions are about 77' x 126', with 18' ceilings. So MDTTC's volume is 77 x 126 x 18 = 174,636 cubic feet. Multiplying by 1728 we get C = 301,771,008 cubic inches. So for MDTTC, we get:

N40 = C x 0.3621 = 301,771,008 x 0.3621 = 109,271,282

So we can fit a little over one hundred million ping-pong balls in MDTTC!!! Since you can buy training balls from Butterfly at about $80/gross, it would cost us about $60,706,267 to buy enough to fill the club. (Could we get a volume discount? Or get cheaper balls at Walmart?)

Suppose we instead used the old 38mm balls. Then the radius would be 0.7480. Plugging this into the volume formula, we get its volume at ~1.753 cubic inches. Then

N38 = (C/1.753) x 0.74048 = C x .4224

For MDTTC, that's 301,771,008 x .4224 = 127,468,073. Another 18 million balls!

By the way, on Jan. 30, 2014, after a rather weird discussion with a 7-year-old, we calculated we could fit 27 blue whales in MDTTC.

Washington Post Reporter and Choppers
The reporter came in yesterday morning. It was a cause of great excitement for the kids. One of them tried to convince the reporter about how he'd floated across the Pacific in a raft with his parents as refugees from China, and that he'd learned to play table tennis with a makeshift table his parents made from a shark, with the net made from shark fins and the ball sculpted from a shark's tooth. (Full disclosure: I came up with the raft story and put the kid up to it. He drew the line at telling the reporter that he was the secret child of Trump and Clinton.) 

The reporter interviewed me for 40 minutes, with a tape recorder and taking notes as well. He followed that with similar interviews with coaches Cheng and Jack. He'll be coming back later in the week with a photographer and to interview our top juniors. Main topics we discussed were: 

  1. How MDTTC came about in 1992. 
  2. How other full-time clubs copied MDTTC, leading to full-time clubs all over the country. 
  3. Cheng and Jack, and their history as former members of the Chinese National Team and why they came to America. He was especially interested in how the Chinese coaches made Cheng into a practice partner because of his playing style, though he clearly was as good or better than some of the players who were played ahead of him. 
  4. The differing styles - especially loopers, hitters, and choppers. 
  5. Our top juniors and their performance at the recent Junior Olympics. 
  6. MDTTC Olympians and other current and former top players. 

This is our last week of camps, and we had a smaller turnout, perhaps 25-30 kids. Since I wasn't needed - we have eight full-time coaches - I was able to watch the session. One interesting thing I noted - we now have four junior choppers. I had thought we had two, but this summer two of our beginning kids have become choppers. One of the new ones is about 1200, the other (a girl) under 1000, but they are both about ten, so who knows how good they'll be someday. (Our #1 junior chopper is Eric Li, 14, rated 2027.) All of our coaches can teach chopping, but our primary chopping coach is chopper/power looper Wang Qing Liang ("Leon"), who used to be over 2600 and made the semifinals of Men's Singles at the 2012 U.S. Open.

No Blog Today
I was busy on USATT work last night from 9PM to 2AM (including a long online discussion on national team issues), and so wasn’t able to do my blog in advance. This morning I’m meeting a Washington Post reporter at the club. So nothing today – but see you tomorrow. Meanwhile, here’s a humorous 3-minute video of Bob Costa defeating Kanak Jha on NBC. And here’s what I’ll call “Cow-Light Pong,” though I really have no idea what’s going on.
