| Feb-11-08 | | Eyal: This last-round game determined the winner of the tournament - Inarkiev going into it as the leader with 7/8 and Timofeev trailing by half a point. 78.Rc7 was an inaccuracy by Timofeev, after which Inarkiev could have forced a (theoretical) draw by 78...f4, exchanging White's last pawn (79.Rg7+ wouldn't help because of 79...Kf6/h6). Later, Timofeev missed a quicker win by 87.Rc3! followed by taking the bishop and winning the pawn race, since the g-pawn would queen with a check. |

<Now Timofeev missed a simple win: 87.Rc3! White will take the bishop and win the pawn race, e.g.: 87...Kd4 88.Rxc4+ Kxc4 89.g4 a5 90.g5 a4 91.g6 a3 92.g7 a2 93.g8Q+ (yes, with check, since the recapture by the black king was on c4).>

| Feb-11-08 | | notyetagm: Recently there have been two good examples of the <STING IN THE TAIL IN PAWN RACES>: A Timofeev vs E Inarkiev, 2008 and J Smeets vs Yifan Hou, 2008. In A Timofeev vs E Inarkiev, 2008, White (Timofeev) missed the idea of <PROMOTING WITH CHECKK>, that is, <FORCING> your opponent's king to <LINE UP> with -your- promotion square so that you can queen <WITH TEMPO (CHECK)>.

| Oct-20-09 | | TheaN: Take note that White's idea after 87.Rc3 a5 would be 88.g4 a4 89.g5 a3? 90.Rxa3 xD. No flashy combinations and whatnot, Black just can't pass the third rank. After 87....a5 88.Rxc4†??, as one user said White can just follow with taking the Bishop, loses for White. In any variation where the Black King moves, White wins a tempo by taking the Bishop and wins the race due to check. |

| Jun-23-16 | | Smothered Mate: According to the Lomonosov tablebases:
After 77. ... Kxg5 , the position was drawn.On move 78, both pawn moves draw and
everything else (including the played Kf6) loses.
79. Ra7 just draws. Ke3 was the only winning move. 79. ... Bd3 loses. Kg5 was the only drawing move.
According to the 6-piece tablebases:
After 86. Kxf5 , the position was still won for white. 90. Kd4 and 91. Ke3 were both only-winning-moves.
The right moves for the 3 ply centered on white's 79 are apparently based on fighting over whether black can exchange off white's pawn. |
