Obstacle dice chess

 In the more conventional form of dice chess, dice are thrown to determine which piece to move. In this version, the opposite is true. A die ( singular form of dice ) is thrown to determine which piece or pawn  is not allowed to move. The outcomes and the corresponding prohibited moves are: 1 pawn , 2 knight, 3 bishop, 4 rook, 5 queen and 6 king. 

To start the opening stage smoothly, the first 10 moves are not subject to the throwing of a die. From the eleventh move onwards, the die is thrown  except in the following cases:

1)       When an enemy piece/pawn is en prise, you can take it.

2)        When one of your piece/pawn is under attack, evade, recapture or   capture another enemy piece/pawn if any of these is possible. Alternatively, make any non-capturing move without consulting the die. This is a compesnation for losing the piece/pawn.

3)        When there is a chance to check, just deliver the check without consulting the die. The side under attack can just deal with the check as in a normal chess game: evade, interpose a piece/pawn or take the attacking piece with the king. 

4)       When your opponent has a clear mate in 1, you are free to move a piece or pawn or the king to prevent that possibility.

5)    When there are only pawns and kings on the board.

This is only an unpolished version. Advice and comments are welcome. 

For every move when the dice rule applies, there is a 5/6 ( 83.3% ) chance that you can really move the chessman you have in mind. 

Another demo game: 

The moves in red are those where a throw of dice is compulsory.  A total of 52 moves are made ( combining the two sides ). 14 throws are necessary. Percentage = 27%

1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.f4 Qa5 8.Bd2 Qa4 9.Nf3 b6 10.Be3 Ba6 11.Bxa6 Nxa6 12.O-O ( when neither a 4 nor 6 comes up ) Rc8 13.g4 cxd4 14.Bxd4 h5 15.h3 Nc5 16.Ng5 hxg4 17.hxg4 Ne4 18.Nxe4 dxe4 19.f5 Nd5 20.fxe6 fxe6 21.Qd2 Rc7 22.Qg5 Qxc2 23.Rf2 Qd3 24.Qg6+ Kd8 25.Qxe6 Qg3+ 26.Rg2 Qxg2+   0-1

Here is a game position which is quite suitable for trying out this version of dice chess.

Black ( to move ) is definitely winning but the key moves are subject to the throw of dice. Play this over with your friend ( with obstacle dice chess rules, of course ) and see if luck favors the weak or the strong this time. 

Just another illustration.
