if you google for pawn duel you'll find the rules on how to beat any IQ level (there are 8 or 9... I forgot) given the fact that you have the first turn.
The game is nicely coded, except the highscore seems buggy. I won the game without loosing any battle with 3900 points, however there is people having 4600 points or even one with 90'000'000ish points... :P
