Hi,
I think position 827 needs to be removed:
[D]8/3R1P2/1ppP1p2/3r4/8/K7/p4k2/8 w - -
White must stop the a2 pawn so the obvious question is why can't he take the a2
pawn? The answer would appear to be that 1.Kxa2 fails to 1...Ra5+ 2.Kb3 f5! You
can give a couple of more checks before playing f5! but the solution is
essentially the same: if you queen with 3.f8Q? you cannot avoid the perpetual.
The problem is that White has a mighty resource available: 3.Ra7!!! Sacrificing
the rook to control the a-file or gain time to queen. 3...Rxa7 4.f8Q Ra5 5.d7
and White is won. Tiger 14.0 gets credit for Ra7 BTW.
