Might be t100, white has just captured a queen. Yes, it is in t100 too. t(2n+2) = or(t(2n),t(2n+2)) Both the even and the odd sets are growing.

No. Black is to move, that is what the 'b' means. >Counting the number of moves for the 50 move rule has nothing to do with >distance to mate.

They are the ones with the information needed by endgames that convert to the current. They are also the ones needed by a chess program to decide if a position is a win for white with a single small i/o operation. They don't tell you distance to conversion.
