{Draw (9+9)     The author comments: "To understand what follows reguires the
following knowledge: If Black can free his queen and knight, he will win the
endgame in a classical 'good knight - bad bishop' fashion, helped by his extra
pawn. This is so because the bK is completely safe in his current setting. The
only exception is if Black plays g7-g6 too early, after which White keeps his
queen near the bK and the threat of a perpetual allows Black to attack the wK
with only one piece, which is insufficient to win".  } 1. Qb1 (1. Bf3 $2 Nxb7
