Today’s 5-second tactics
WEAK BACK RANK
im Glavina, Pablo
Iagar, Razvan (2170)
VII Open Internaciona/Zaragoza.2013.12.27 Position after White’s 28th move. A complex fight in a Benoni has resulted in White’s forces being disorganized as well as his back rank vulnerable. This last detail gives Black opportunity to strike a lethal blow.
Clearly White has no choice but to capture the pawn. Ofcourse, taking with the h-pawn gets mated in one move!
Now insufficient is the hasty 29…Qf7? as 30.Rf3 defends everything. Notice that the White Queen must cover the f1-square. Is there a way to deflect her?
BLACK TO PLAY AND WIN!
gm Peralta, Fernando
Suarez Gomez, Julio
Zaragoza, as in the previous exemple. Position after White’s 39th move. Ofcourse, Black is winning, being 2 pawns up, but Peralta displays some nice artistry here.
WHAT IS BLACK’S FASTEST WIN?
gm Yermolinsky, A
North American Open; Las Vegas/ 2013.12.29 Position after 33 moves of play. Despite the extra pawn, Black finds himself s paralyzed and unable to create play. White’s active Rooks (one on the 7th and the other on the h-file) are un-opposed, while White’s Knight is also actively posted. All that is missing is to find a way for the White Queen to join in the party…
WHITE TO PLAY AND WIN!
SOLUTIONS VII Open Internaciona/Zaragoza.2013.12.27 Iagar, Razvan–Glavina, Pablo: 29…Qa7! 30.Qd3 c4! 31.Qxc4 Qa4! 0-1 The weak back rank costs White too much material just to avoid mate!
VII Open Internaciona/Zaragoza.2013.12.27 Suarez Gomez, Julio–Peralta, Fernando: 39…Nxf2! 0-1 Taking the Knight allows …Re2. Not taking the Knight is even worse as …Qh1+ is threatened.
North American Open;Las Vegas/ 2013.12.29 Gareev, Timur–Yermolinsky, Alex: 34.Qf3! Threatening 35.Rxe7!Qxe7 36.Qf6+ forcing mate: 36… Qxf6 37.exf6+ Kg8 38.Nh6+ Kh7 39.Nf5+ Kg8 40.Ne7# 34…Rg8 (best. If instead 34…Rh8 loses without a fight after 35.Rxh8 Kxh8 36.Qxf7) Now the most direct way to win is 35.Nh6! Rf8 36.Nxf7!! Rxf7 ( 36…Qe8 37.Nd6 Qd8 38.Qg4 Rb2 39.Qxe6 Rfxf2+ 40.Kh3 is no better ) 37.Rh7+! etc
