Queen Alice

This is the newest site I am playing correspondence chess in. Just started playing a few days ago, and I already have a couple of games running (already lost in one!). Rating system is a bit different from Schemingmind.com since there is some sort of a provisional rating period for the first 25 games you will play. Only after will your rating be considered "real". The manner of computing the rating is also a bit different, though it's possible that the approach is different, but the statistical implications are the same (maybe someone could enlighten me?). Schemingmind.com follows the ELO system with a standard deviation (SD) computation to give it a more "relevant" scenario (meaning, the SD allows one to see if the rating given is highly volatile or more or less stable, since a lower SD would indicate that the player is playing (and finishing) a considerable number of games to make the computations relevant, and vice versa.
Also, the ELO system employed at Schemingmind.com allows for computations on a monthly basis, while ratings are computed at QueenAlice everytime you finish a game.

Give it a try! And don't forget to look for me there! www.queenalice.com Read More......

Deep Blue




I had the privilege of going to Washington D.C. for about a week, and got a chance to see Deep Blue in one of their huge museums. Deep Blue is the chess program that IBM developed which was able to defeat Kasparov twice, the second game lasting only 19 moves as Kasparov decided to resign. On display was one of the two tower processors (not at all different outside to the usual CPU, it's the black tower to the right side) which is the hardware for the Deep Blue program, as well as the chess table and other chess paraphernalia used during the match.. As the match between human and machine happened a few years ago, and given the exponential development in computing speed, I wonder if the common chess engines today had already exceeded Deep Blue's computing capabilities. Maybe it has. IBM decided not to host anymore matches between humans and programs, as they stated that their goal is to improve on computer's processing capabilities, not to create a mechanical champion. I wonder where it would have led us if they had decided otherwise. Read More......

Correspondence Chess

It's been two months now since I signed up with www.schemingmind.com , one of the several dozen sites dedicated to correspondence chess. So far, it has been such an enjoyable experience. The site allowed me to play against a variety of players I may never even get to meet in person. Although it requires somewhat a different discipline compared to live on-the-board chess games, it allows people like me who are interested in chess to pursue learning and improving on the game at my leisure, since there is no fixed schedule to follow (moves are timed, however, but each move has several days as deadline). The site also opens one up to a host of players who share resources and tips through private comments and open forums. So, if you happpen to be a chess afficionado or simply an occasional enthusiast like me, give it a try! :-) Read More......
