Yes and no. There is one, and it's free, but you can't play against the computer, as far as I know. Only 1v1 or 2v2 human players...
It's called Chess4 and can actually play four variants of chess. Here is it's description:
And here's the link to download it on the AppStore: http://itunes.apple.com/fr/app/chess4/id377654788?mt=8#Chess4 is a fun multiplayer chess game for the iPhone and can be played with 2 or 4 players. Chess4 has 4 game types built in. They are: Normal, Suicide, Crazyhouse and Bughouse. All game types are played on one device except Bughouse, which is played over a Bluetooth connection with two *iPhones / iPod Touches.
I guess that if you want a computer opponent, sending a supportive email to Chess4's author would be a good start.
BTW, does someone know about a program that can play bughouse or crazyhouse? I can't remember one, even on PC! Oo
and TJChess can play bughouse and crazyhouse.
