33.R6c5? [ He really just needs to trade down. Losing an exchange to get closer to an endgame down only one pawn while up a piece is really the way. I guess he was greedy, that's one of the seven deadly chess sins. 33.R6c3 Bxc3 34.Rxc3 Re7] 33...d4 Diagram

36.Re8+? [ >=36.Rc8+ Kg7 37.Rce8 Qd1+ 38.Kg2 Qd2+ White is up a buttload of material. The worth of a queen is under some debate, but it is agreed that she is worth somewhere between 8 and 9 pawns (although there is at least one position where 3 pawns beat a queen).. also the king is worth 4 pawns in the ending, according to one source, meaning that if the king is active, his side is up a minor piece (knight or bishop) plus a pawn, so could sacrifice less material than that and win.. Meanwhile, black gets to add one pawn to the balance, so if we cancel 3 pawns for both sides that is between 9 and 11 pawns for black. It is well accepted that rooks are worth 5 pawns each (although it should be pointed out that in the endgames of the endgame encyclopedia published in Belgrade, Serbia 4 pawns are resoundingly winning over a rook, while three pawns seem to draw or even win if advanced enough (though we shuld really upgrade the worth of an advanced pawn). Final tally: Black: 12-14 pawns White: 16 pawns two pawns is a good rule of thumb for a clear win, barring anomolies such as the opposite color bishop endings and rooks where the great strength on offence and defense in an open board makes drawing a game two pawns down with rooks on the board not completely infeasible. besides all this, the mighty d6 pawn is dead as a doornail, and white has the advantage of the outnumbering 3 to one. another rule of thumb is that two rooks can hope to win a pawn as they sacrifice them for a queen and if that would happen white would be up a whole piece. however, black would have to lose one more pawn in this scenerio at this point because the d6 pawn will be for free or at the cost of only one rook. perhaps there is a perpetual.... 39.Kh1 Qe1+ 40.Kh2 Qf2+ 41.Bg2 nope. Diagram

] 36...Kg7 37.Re1?? instead, white makes a terrible blunder. Diagram

37...Qf6+ 38.Ke2 Qf2+ 39.Kd3 Qd2+ Not only will white lose a rook, but the queen will be taking that rook with great hopes of queening the mighty d6 pawn. The king cannot maintain his attack on the pawn without masking the rook's attack. After spending a tempo with QxR there will be a good chance of more checks giving black time to queen. This was too much for white to bear. Diagram
