Siberian Chess

Siberian Chess is a very competently made chess program developed in Siberia, hence the name. It presents quite a variety of options and settings, and provides a tough computer opponent to play against. (And also an "Easy mode" if you need it, which I definitely do.) You can enter your moves via the keyboard, mouse, or entering the move directly (ex, b2b3). The game displays all of the moves, allows taking a move back if needed, you can save and load your game, and even edit the board however you'd like. Looks decent as well. Seems like a great option for chess enthusiasts.
