This position can be solved by a program (with correct score) by making it use a
2-move rule instead of a 50-move rule :)

Although it would screw up the program's performance on every other test
position, it will solve this one. I wonder if this method can be used somehow in
a strict way to allow the program to solve this position, yet not disturbing its
performance on regular positions.
