Qf5 Rxd1+ 23. Rxd1 Rd8 24. Nd5 Bxd5? A grave error of judgment, which gives White a very dangerous passed Pawn in the centre. Instead 24. ... Qe8 seems to give Black a tenable position. 25. Rxd5 Rxd5 26. cxd5 Qg5? Another very questionable decision. Better looks 26. ... Qd8 in order to answer 27. Bc4 by 27. ... b5.

27. Qd3! Here 27. Qxg5 hxg5 28. d6 was also very tempting, since after 28. ... Kf8 29. Kd2 f5 30. Kc3 the ending looks very sad for Black. 27. ... Qxg3 28. d6 e4. After 28. ... Qh4 29. d7 Qd8 30. Qd6 Nf8 31. Bb5 Black finds himself in a kind of strategic Zugzwang, and giving back the extra Pawn by 31. ... Ne6 (31. ... a6 32. Bc6 makes no difference) 32. Qxe5 a6 33. Bc6 doesn’t seem to be going anywhere. 29. Qd1 Nf8. Thus resigning himself to play a Piece down. However, if 29. ... Qh4 then 30. d7 Qd8 31. fxe4 with an overwhelming position for White, e.g. 31. ... Ne5? 32. Qd5! (not 32. Bb5 a6!) 32. ... Nxd7 33. Bb5 and wins. 30. d7 Nxd7 31. Qxd7 Qe1+ 32. Qd1 Qf2 33. fxe4 Qxg2 34. Bc4 Qf2 35. Qd2. The safest way to exploit his material advantage.
