＞ 今現状でPCの普通の市販チェスソフトにチェスのトッププロが敵わない http://en.wikipedia.org/wiki/Computer_chess
Chess-playing computers are available for negligible cost, and there are many programs (even the free GNU Chess, Amy, Pepito, Crafty, Beowulf and more)
that play a game that, with the aid of virtually any modern personal computer can defeat most master players under tournament conditions,
while top commercial programs like Shredder or Fritz have surpassed even world champion caliber players at blitz and short time controls.

The system derives its playing strength mainly out of brute force computing power. It is a massively parallel, 30-node, RS/6000, SP-based computer system enhanced with 480 special purpose VLSI chess chips. Its chess playing program is written in C and runs under the AIX operating system. It was capable of evaluating 200,000,000 positions per second, twice as fast as the 1996 version. In June 1997, Deep Blue was the 259th most powerful supercomputer.

The strongest programs are as weak as players that have played the game for mere months, and are no match to a seasoned player.
In contrast, for chess there is a simple rule of thumb "knight and bishop worth 3 pawns, rook worth 5 pawns, queen worth 9 pawns, checkmate is infinitely bad"

The best Othello computer programs can easily defeat the best humans. As early as 1980, the program The Moor beat the reigning world champion, and in 1997, Logistello defeated the human champion Takeshi Murakami 6:0.
This dominance is not seen in games like chess, where the best computers are about equal to the best humans (although the Hydra machine may soon change that), or
Go, where even average human players trounce the best computers.
