Bb1 g6 Blunting the b1-h7 diagonal, but this comes at a price of weakening the dark squares around the king, while the white bishop on b1 finds an alternative diagonal to occupy. 16. Ba2 Nd5 17. Ne4 Qd7 18. Bh6 Ba8 19. Nfg5 Nf4 20. Qf3 The queen stops one square short of her best square 20. Qg4! Nxd4 and now the knight is not attacking the queen like when she is on f3, which allows 21. Nxf7! Bxe4 (21... Nfe2+ 22. Kh1 Kxf7 23. Rxe2 Qc6 24. Qf4+ Nf5 25. Rde1 and the pressure on e6 and the open Black king give white a big advantage.) 22. Nxd8 Rxd8 23. Bxf4 Bf5 24. Rxd4 (24. Qg3? Ne2+) 24...
