Friday Night

So there I was at the stroke of midnight, contemplating the four-knights opening by the dim glow of a flashlight, ears popping under the extra five pounds per square inch of pressure.

On Friday night, Dan (who you may remember as the Robot9000 bot author), Elizabeth and I invented midnight underwater speed chess.

A nice feature is the naturally-enforced clock.  You have as much time per move as you have air in your lungs. Protip: don’t use a glass set.

Now we just need to combine it with chess boxing.

    We never did finish the second game!

    Underwater speed chess boxing – sounds fun.

  3. xkcd says:

    > We never did finish the second game!

    Can we add “insufficient oxygen” to “insufficient material” in the draw rules?

  4. relsqui says:

    Shame the actual photos didn’t come out. We’ll bring more lights when you two go to finish the second game.

    Mostly I’m put out that now we don’t get to show off the floating stuff we rigged for the purpose.

  5. Guybrush says:

    How would one weigh the pieces down?

  6. Carsten Otto says:

    I know people that play cards 10m under water. A nice training if you are somewhat experienced with apnoe diving :)

  7. Paul says:

    I would think a good magnetic chess board would be good for underwater chess.

  8. zigdon says:

    We were using a glass set I had, so the pieces were heavy enough to stay properly, as long as a stray stream of water didn’t hit the board.

  9. digitrev says:

    Wow. If I actually played chess, this would be amazing.

  10. Great idea, I should try that as soon as I go back to Guadeloupe !

  11. Seth says:

    Wow. That would just be awesome all around. Good apnea training. Where in Boston are you doing this?

  12. techer says:

    There’s a version some people I know play that is drunk chess boxing–drink a round (booze or water-equivalent), a round of chess, then a round of boxing. Not sure how well that would mix with underwater speed chess though before turning into speed chess boxing drowning.

  13. mike says:

    i used to have a heavy-as-hell, hand-carved marble chessboard that i bought at a yard sale for forty bucks. it was smashed to shit by a bunch of idiots at the boarding school i used to go to. it would have been perfect.

  14. Dan says:

    I read it wrong at first, thought you meant midnight underwear speed chess. I thought, hot.

    Oh and what the hell at the CAPTCHA for this comment… how the hell do I write 17 3/4? Seventeen and three quarters? That’s the longest CAPTCHA ever…

    Oh and what the hell at the CAPTCHA for this comment… how the hell do I write 17 3/4? Seventeen and three quarters? That’s the longest CAPTCHA ever… Going to try it. If this posts twice you’ll know why.

  16. Mort says:

    Protip 2: don?t use a wooden set.

    this would work well with my brother; he doesn’t play chess but does dive whereas I do play chess but can’t hold my breath for very long.

  17. Special_K says:

    Hmmm… very eeenteresting. I suppose that this disqualifies chess computers, unless their operators do the diving. Still, even then, not as fun. Now, computers in chess boxing, that’s where the fun is: one of those US Army killbots that went crazy in Iraq, armed with the thinking power of deep blue v. Gary Kasparov, armed with an M16.

  18. binaryb says:

    Boxwood (the wood that is most commonly used for chess pieces) is one of the few woods that is denser than water, so that you probably -could- use wooden pieces.

    I, however, would counsel making your own set, designed to withstand at least mild currents (whatever the equivalent of “aerodynamic” would be underwater), and made of steel or something appropriately heavy.

  19. Kristoaster says:

    David Blaine would own at this (recently held his breath for 17 minutes or something)

  20. James says:

    Yeah, by the time he finishes his turn the person on the top forgets what the board looks like and all hell breaks loose ;)

  21. Jekka_Lynn says:

    *Sighs* Sadly I can neither play chess or swim so even though this does sound like fun for me i is out of the question…*pouts*

  22. Josh says:

    It’s never too late to learn, Jekka_Lynn =)

  23. James says:

    If this is another case of life copying xkcd, i wonder just how many drownings this comic will cause…

    Underwater-chess responsibly, everyone!

  24. superkp says:

    What exactly is this apnea that people have mentioned (I assume it is a breath control technique)? Any tips other than materials? I’ll bet this would be great training for mental chess as well, considering that you would have to visualize it more often than you would actually see it, considering the trips up, down, and time spent recovering/breathing.

    I wonder if dolphins can learn chess?

  25. ThemePark says:

    Or you should build an underwater rollercoaster (and I don’t mean one that travels beneath water, but one that actually goes THROUGH water) and combine this sport with your chess photo.

    http://xkcd.com/249/

    CAPTCHA: that Kenney. Indeed.

  26. Skyer says:

    maybe they could, but movement would be hard, unless you used pieces that were REALLY heavy, or maybe had a big board. assuming they would move with their noses, wouldn’t the pieces be to close together?

  27. The_Duck says:

    This is the best idea I’ve heard today.

  28. Alec says:

    This is perfect…

    Unlike those automated can openers, which although bring me glee at the potential laziness, bring about my fear of an ever possible robotic rebellion… if the Republicans win this election, I will need to work on a Robot Plan, and likely a Zombie Plan…

    Back to the subject…
    If the chess pieces illuminate, a lot easier to play…

  29. Aaron says:

    midnight underwater chess, alternating rounds of one on one waterpolo in between, 1 minute break.

  30. Phil says:

    Am I being retarded in that I went out of my way to do histogram equalization on the image so I could actually see it?

  31. Jayhawk says:

    Apnea (or apnoea) is the cessation of breathing. Most people know the term from “sleep apnea”, which is when a sleeping person ceases breathing for short periods during the night.

    Apnea diving is an extreme version of “free diving”, or diving without any breathing apparatus. Apneists can hold there breath for extreme lengths of time and can dive to great depths with training.

    Ugh, “their” breath. Not “there” breath

  33. Luke says:

    Slightly OT, but-

    I’ve never been impressed with the idea of chessboxing. I mean, alternating rounds of boxing and chess? There HAS to be a better way to fuse the two games… so here’s my idea:

    The chess game is played by individual boxers standing in for the pieces, like the “live chess” played at so many lame renaissance fairs (or Battle Chess, for the slightly-less-geeky). The difference would be that captures are not automatically awarded, but are decided by a one-round boxing match between the two “pieces” involved, with the losing boxer removed from the board. The chess players for each side take the role of the king, so they have to be decent boxers as well.

    The possibility of losing a capture would change the strategy of the game substantially. Also, you would need to decide which of your boxers plays which piece, requiring you to match up different skill levels during play, and keep track of each player’s fatigue as the game goes on.

  34. omis anon says:

    well the idea about chess boxing is physical stress combined with mental stress right? so why don’t you just make the chess pieces really big, this will serve two purposes the bigger bases will allow them more stability, and the in creased surface area and distances will require you to swim with them pushing against water. You could make moving pieces subject to water polo rules (kings pawn to D4 intercepted by a diving tackle).

  35. Tman930 says:

    You know those “World’s Strongest Man” competitions?

    I’d like to see those guys play chess, and have to lift 450 lb. chess pieces to move them.

    …underwater?

  36. shinybaby says:

    i love this concept! when i was a little girl i used to have the classic imaginary tea party with the underwater twist! couldn’t get any of my friends to attend, but that’s cool… that’s where the imaginary came into play, right?
    some things are just that much more fun when you do them underwater!

  37. Brian says:

    This is awesome! But not quite perfect.. Well, as perfect as human beings
    I feel bad that I’m the first person to point this out, but if you don’t trust the person you’re playing with, there isn’t much of a way to tell if they cheated, unless you go down with them each time. Otherwise, perfect. I used to springboard dive, and would lounge on the bottom of the pool all the time. Just like if I were on the beach..

  38. James S. says:

    For the more patient (and those with substantially better lung capacity), there’s always midnight underwater speed Go. Though I guess the “speed” thing defeats the purpose of playing Go.

  39. Alex says:

    Midnight Underwater Charades!

  40. Aerophina says:

    For the LoTR fans here… midnight underwater tig?

  41. robynneiscool says:

    I’ll be more properly impressed when someone invents underwater monopoly.

  42. Will says:

    Eew, pounds per square inch :<

    For anyone who was curious but not quite enough to work it out, the chess board is about 3.5m down (or 1/64 furlongs for you Americans)

  43. Alec says:

    There was a monopoly game put on by the New England Divers Club like this. They somehow got Parker Brothers engineers to create a 42 pound waterproof set. All the pieces had metal in them, and the board itself was very heavy and magnetic. Once news of this had spread other groups of scuba divers set out to break the record they set for longest underwater monopoly marathon. The record holders were a group that played a 100 hour marathon that was briefly interrupted because of a possible thunderstorm. But they had scuba equipment. What would

  44. micksam7 says:

    so it’s one breath per move then?

    Would suck playing against a experienced diver wouldn’t it?

    Or a dolphin.

  45. crackers says:

    I knew a lead chess set would come in handy for something other than firing it out of a cannon, now to obtain the pool

  46. VDOgamez says:

    Wow… How about underwater twister? That would be so much fun!

    PS: Captcha was “Strip Golfer”! That is so disturbing…

  47. Rog says:

    Great idea! It reminds me of the time my buddies invented bingochesquerships, the hybrid game on the century!

  48. ThemePark says:

    Bingochesquerships? Sounds like something I’d play!

    CAPTCHA: souht string. Souht isn’t even a word, is it?

  49. Eric says:

    I can’t wait for someone to post pictures of this. It sounds like a lot of fun.
