16th World Computer Chess Championship In Progress
vmartell writes "The 16th World Computer Chess Championship is now in progress in Beijing, as part of the Computer Games Championship. Currently in the lead are Rybka 3.0, recognized as the world's strongest chess engine and Hiarcs, another commercial engine. Another curiosity is a Java ME based engine running on a Nokia phone, which is currently being trounced by the other engines. A very interesting sideline: before the computer tournament, a Women's Grandmaster played two games against Rybka. The result? Rybka won both games!"
The sad reality is, yes the women certainly can't compete with the men in top level world chess. I'm not sure who it's sad for though - the men or the women. You see to be great at chess you have to be obsessive about it. The more situations you've seen, the greater your ability to avoid lines of play that look good on instinct but leave you in a hole. So world champion chess players tend to be even more obsessive and single minded (to the exclusion of almost everything else including social interaction) than other world champions. People who get that good at chess don't do much else. It's like OCD on OCD. They study study study and study some more. In a lot of ways it's self destructive. Most women just won't do that to themselves. I believe this is the real reason women aren't as good in chess. They're not stupider than men, they're actually smarter.

There are several commercial use for better engines:
1) Game analysis. When you have played a game against and lost, you try to understand why you lost. Sometimes it is because you made an obvious blunder, but when you get better at the game, you start loosing for strategical reasons (lost control of a certain square, etc, etc). Having a good engine helps you try new ideas, and play a lot of what-if scenarios
2) Game understanding. When you follow a live tournament between grandmasters, having a good engine can give you an explanation about what the underlying ideas are ("Why doesn't he plays Nb6? You try it, and get the answer instantly")
3) Correspondence & Centaur Chess. Correspondence chess are long running games where both players have access to whatever they want. It delivers very subtle games, where the strategy is a very important aspect, as all the tactical blunders are removed by the use of good chess engines. Centaur chess is the same with lower time control.
And, of course, bragging rights are important too: having a better engine than other people in the chess club is a bit like having the better graphic card among fps players...
As you may have seen, playing against the engine is not one of the uses. Rybka is supposedly at 3200 elo. By definition, 200 elo points higher means you have a 75% win probability. The current world champion is at 2800, which means that he have a 6% win probability against rybka. Good club chess play is around 2000 (it takes several years to reach that level -- at that level, you can generally play blind, or multiple opponents, etc, etc). Such players have a 1 against 4000 chance against a 3200 player. Which means zero chance...
