There are only 7 pieces on that board. I suspect that two get traded off and crafty sees the real answer. In other words, the test suite answer is probably wrong. With a board that sparce, if you have the tablebase files, crafty will get an answer equivalent to a super GM (IMO-YMMV). It appears that axb6 will result in a draw. I do not know that any other move will give a win. What do you think?
