Is this defendable? 15... d8d6 Although this  could have lost at once, it is an ingenious idea. In anticipation of the  forcing game line, Black defends his knight in a strange-looking way. 16. f3g5 A sparrow in the hand... Gelfand knew this is good, and it was  his plan. 16... e6a2  17. b1b2  17... a2a1  18. e1g1  18... c8a6 The point. Ivanchuk is back in the  game. 19. b5a6  19... a1a6  20. f2f4  20... d6f6 Same idea as before, but this is not optimal. 21. g5h7  21... a6d3 No more chances for a rapid kingside assault allowed! 22. h7f6  22... e7f6  23. f1e1  23... a8d8 For the exchange, Ivanchuk has a pawn and a  relatively safe king. He should be OK now. 24. e1e3  24... d3c4  25. h4e1 Now White can prepare and execute d2-d3! 25... c4e6  26. d2d3  26... d8d7  27. b2f2  27... g7f8  28. f4f5 The white forces are unified so this cannot be bad. 28... e6d6  29. e3h3
