Also, any program that doesn't evaluate the resulting position at something like -2.00 or lower has nothing to be proud of. I'm putting together a suite of positional problems to evaluate programs' understanding or lack thereof, and I'll have to include this position as an "avoid move" type of problem (even though it's a little unfair to Fritz, which will of course fail this one). Can you tell if Gandalf wants to play 21.Re2 in order to follow up with 22.Qe1? If so, that would mark it as the only program so far to demonstrate some concern about the queen's situation.
