1.57.21U - Virtual Chess II; bm=e3g4;

Here's a position that might be fun to check on your chess
programs. Diep played N-f1 but try inputing Nxg4 and watch
whether black recaptures with the pawn or the Queen. If the pawn
captures note how the black Queen becomes imprisoned. Check the
eval of the program. Do programs still struggle with this type of
position? Rebel 8 likes Nxg4 but also likes the pawn capture for black.
So my quess is that these positions are too long range for computers
unless some kind of mobility code is included. I think a human with
the white pieces would have an easy win here with the Queen locked in.
