I am afraid not. The applet serves two purposes: act as an 'electronic chess board', where a single player (or a pair sitting before the same computer display) can see and manipulate the entire board, or to play against an AI. But the AI handles two-player zero-sum games with complete information. For games where (a different) part of the game state is hidden for each player, like in your variant, you would need a completely different type of AI. Conventional chess engines are completely useless for that.
