I would say the explanation lies more in black's failure to drum up some sort of kingside attack. 26.Nxb7] 26.Qxc7 Qxe4 27.Qc1 Qxd5 Diagram 28.Qc6?! [ The last few moves have been in agreement with Fritz. It does seem ever so slightly daft to go for an ending for white here, however. Conventional wisdom dictates that pieces have the advantage in the middlegame. It's true, however, that white has back rank problems. Perhaps he thought that after 28.Qc2 e4 29.Rd1 ( 29.h3?! Be5) 29...Qh5 30.Rxd6 Be5 31.g4 Qxg4 32.Rd5 Qf3+ his problems would continue. Fair enough.] 28...Qxc6 29.Nxc6 Kf7 according to Fritz, white's advantage has diminished by half a pawn since the queen exchange. If he is still winning, this would not be bad. however, I believe Fritz when he claims the advantage to be less than a pawn. Part of the reason, I think, that white felt compelled to exchange was that his pieces are ever so slightly clumsy in the face of black's. With his king gaining superiority now, black could have some serious compensation in the form of the d6 and e5 pawns as they advance. 30.Kg1 d5 31.Re1 Diagram [ Something strikes me slightly wrong about white's move. I like the activating suggestion of Fritz... 31.Rf1+ Ke6 32.Na7 Rb8 33.Bc5 though if you ask me, black is gaining ground here.; the variation 31.Bc5 e4 is not turning out as well for black. 32.Bd4 Rc8 33.Rf1+ Ke6 34.Bxg7 Rxc6 taking off the superior blocader a la Nimzowitch 35.Rf6+ Kd7 36.Rxc6 ( 36.Rf7+) 36...Kxc6 37.Kf2 Kd6 38.Ke3] 31...Kf6? 32.Bc5?
