The Uncertain Chess

I am an Indie Developer working on a Game idea that requires a dice to Play chess.

Unlike Traditional Chess, i have added an Uncertainty(using the dice) element to the chess game where every attack-move means a sure shot kill making it difficult for a novice player to win against a seasoned player.

In the Uncertain Chess, every time the player is attacked, the defender needs to throw a dice. The dice defines the defense grade or the result of the attack. Either the defender dies or due to high value of dice survives and kills the attacker itself.

But yes, it also makes a few moves completely certain i.e. a sure kill(e.g. when a Queen or a King attacks opponent King)
