{This is a very complex study, involving an underpromotion by Black and
reciprocal zugzwangs. White's queen finally defeats Black's collection of
minor pieces thanks to Black's poor king position. However, the interesting
play must be balanced against the heavy initial position, in which Black's
king has been artificially placed in a box.} 1. Ne2 $1 Nxe2 2. h8=Q {
