position 2 is 100% draw, position 1 is a hard draw - black has very good chances
of losing this if he doesn't know what he's doing. any sophisticated evaluator
should understand that too! if you return a draw score for both, you might end
up on the weak side of RB-R because your engine believes it's a simple draw...
