Hi,
is this game a draw or a win for Aristarch v4.37. 4.37 moves a pawn as white in move 85, it then mates exactly on move 135. Is this a mate or a draw according to the 50 move rule?
Thanks
Robert

It is a win for white.
There is no doubt about it.

Thanks, how does this 50 move rule work exactly?
This was a mate at exactly the 50ieth move of the same colour (white) that last moved a pawn, it is a mate. What if black had mated in this game at the 135.th move? Still a win for black (50ieth move after the _response_ to the white pawn move) or is this already a draw according to 50 move rule?
Thanks
Robert

If it is one ply later it is a draw in case that a draw was claimed by one of the sides one ply before the mate(otherwise it is a mate).

Just to say same thing as Uri, but in other words:
when mate and draw meet perfectly as in posted game, mate "wins".
If mate comes as _response_, draw "wins".
