*Now* he tells us! OK, you are the exchange up, control
the only open file, and can win material at will. So -- purely
a guess! -- Fritz, Crafty, Rybka and any other engine except
possibly Sanny's is scoring your position at +3 or more? ...

Suppose Crafty_12 ply
penalizes either move as inferior to the other --
how does this style issue contribute to ranking
the world champs *accurately*?

... In which case this position is outside the [-2..2]
range, and is discarded by the G&B methodology, really for exactly
the reasons you gave. So Crafty12 would not penalise your move.
