Nd4 Na4 {Black's forces are offside and White has a huge army ready to do battle against the enemy king.} 24. Nf5 {Not only d oes this attack the queen, but it also unleashes the power of the bishop at b2. Black does not have time to capture it, because he must save the queen.} 24... Qc6 { Now the king is almost completely without defenders, so the sacrifices begin.} 25. Bxg7 { Obviously the bishop cannot be captured because then Ne7+ would win the queen.} 25... Qxd5 {Black hopes that White will capture the queen, allowing the saving move 26...Rc1+. But White has a much stronger option.} 26. Nh6+ { Now Black has no choice, there is only one legal move.} 26... Kxg7 27. Qg4+ { and here Black resigned, because 27...Kh8 allows 28.Qg8 mate, while capturing the knight is no better:} 27...
