{Judge Yochanan Afek: "In the heat of the battle each side promotes a second
queen; however the side that sacrifices both his queens is the one to emerge
the eventual winner against the remaining enemy queen. A breathtaking battle
with plenty of quiet moves and subtle finesses."} 1. f6+ (1. Qc3+ $2 Kg8 2. Kd6
