Peter, I try to do it correctly for Yace. But as a Winboard engine it is
difficult. There is no command to tell to Winboard "I am no doing the 100th half
move (which is not a capturing move, pawn push) after the last capture/pawn
push, and I claim a draw with this". Tim Mann suggested, to just send the move
to Winboard, and then send the draw claim (by "1/2-1/2"). Similar with draw by
repetition. You have a recent version of Yace, perhaps you have the time to
check, if this is not done properly.

Other WB-GUIs I know, will make the decision for the engine, so there is not
much the engine author can do.
