If you see the tittle, you could think it's a chess game, but unfortunately it isn't.
"War Chess" is a kind of battleship game, extremely slow and very bad keyboard response.

In the first game we must to put the ships in the board, and it is really maddening. Luckily, we can press escape to go to the fight screen.

In the next screen -the keyboard continues working bad-, we have to attack the enemy. I sank a boat without moving out of my position.

If you decide to play, remember to begin the game pressing Esc (thanks Konamito).
