However, I do recall that Sierwan talks about it at length, and even demonstrates positions where you can remove the bishop from the board with no effect. It is obviously something he strives for in a game. It might have been the strategy book. Anyway, here is a fairly obvious example of the principle: r1k2br1/p7/Pp1p3p/1PpPp1pP/2P1PpP1/1K3P2/8/8 b - - Black is "up" 13 but if the bishop were a different color, the whole game changes instantly. As it is, it is an obvious draw. This is the garden variety "bad bishop" but any variation on this theme will render the bishop useless (as in the game at hand).
