Declining to Decline - the Battle

Here's a battleship game using foreign names in Russian press: how do they decline?

Play the game!

Note: "computer skill level" is how good you want your opponent to be. To play the game, click on the squares on your side - the blank side - to try to locate your opponent's ships. If you answer a question correctly, you score a hit; if you don't, you have to take a second shot. Hit each square in a ship to sink it. To win, sink the computer's ships before it sinks yours.
