Beren the 32nd 
Subjekt: Probability Chess
Playing a game of Dice Chess at the moment has given me an idea for a new variation "Probability Chess" (better than dice chess I think).
Instead of a simple dice dictating which type of piece you can move, piece probabilities are calculated first, based on how many moves with each type of piece are possible.
For example, for white's first move there are 16 possible pawn moves, 4 knight moves but no others. Based on this Pawn is assigned 80% and Knight is assigned 20%. Then a randomiser determines which type of piece must be moved accordingly.
To illustrate this further, let's look at how a game might proceed. If white must move a Pawn and plays 1 e4, and then black must move a pawn and plays 1 .. c5, then white has 30 possibilities for the 2nd move: 15 pawn moves, 5 knight moves, 5 bishop moves, 4 queen moves and 1 king move. Based on this Pawn is assigned 50%, Knight 16.67%, Bishop 16.67%, Queen 13.33% and King 3.33%. White has a good chance now of being able to develop a piece, but if Pawn is chosen again then white should choose a move that takes into account how this will affect the probabilities of being able to move certain pieces next time. Later in the game you will be affecting your opponents piece probabilities too!
This is where a lot of the skill in this game will be, and what makes it more fascinating than Dice Chess.
Who thinks this sounds like a good game for BrainKing to support?
