Black is in trouble. His only chance is sacrificing the exchange on d6 in order to liberate the a8-bishop. 22.g4 This move suggests itself; however, it gives Black some respite.

[After the simple 22.h5! g5 (22...£f6 23.hg) 23.f5 all of Black's illusions would have been dispelled.]

22...¤f6! Black's best chance. 23.g5

[¹ Stronger is 23.h5! ¤g4 24.£g3white stands better‚ and again Black's position is just bad.]

Of course, White is winning but his opponent manages to find some counterplay. 28.h5 c5 The black bishop is activated. 29.d5 This seems to be a forced continuation; all the alternatives are worse. 29...¥d5 30.hg

[White would have experienced serious technical problems after 30.h6 ¢h7 31.£g4 ; there seems to be no forced win for him.]

35.¦d5? -2.01 Perhaps, it was a time trouble. However, Black also has some potential after White's other continuations, in connection with his passed g-pawn.
