Hi Gerd, >Isn't b) redundant? > >I mean if you have already a 3-fold repetition where your opponont didn't claim >a draw before, doesn't that imply that you can force another 3-fold repetition? I agree, in a game theoretical sense, it should be redundant. However, it will allow slightly different consequences. You don't have to write an additional move on your score sheet. You can immediately stop the clock, instead of remembering the move, that will yield in the next repetition. I did not look at the rules while under time pressure anymore - perhaps it could make a difference there, too. But, I agree with you, rule b) would not be needed. OTOH, for a wb-engine running under WB, rule b is the only one, how it can behave correctly for claiming the draw (because of deficiences in the WB-protocol). Cheers, Dieter
