Dann, Here is the Shirov Kasparov game I mentioned. I just picked a random game. As can be seen, this game maxed out at 142 bits (if Shirov would have castled, say at move 13, it could have been 150 bits or slightly higher). The two numbers on the left are the number of bits required after each move. The entire advantage of this schema is that most black pieces do not require a color bit until a white piece or pawn is taken. Once this happens, (in this game at move 3 since it was a Sicilian), that condition no longer holds. However, only 2 pawns or one piece have to be taken in the entire game to basically ensure that 160 bits is the maximum, so by move 4 in this game, the chances of it going above 160 bits are negligible. It would be interesting if someone could find a position from a real game that could get to 161 bits or more, but I doubt that will happen.
