Reykjavik Open  2016.3.14  gm Dvirnyy, Danyyil– fm (2350)Hedman, Erik.  Position before Black’s 19th move.  A sharp (typical) Benoni!  I like Black, who has the Bishop pair, but White’s strong presence in the centre is always a worry for the second player.

Correct now is 19…Bd7(!), mobilizing the last piece and helping to coordinate his pieces.  It also adds protection to the Rook on e8 and prepars an rapid b5.  INSTEAD, Black rushed things …

19…b5 (?!)

It is curious how a very small detail can make such a big difference. Black is now lost! Do you see how?

WHAT IS WHITE’S WINNING IDEA?

Reykjavik Open  2016.3.13  gm Shabalov, Alexander–gm Gupta, Abhijeet. Position before Black’s 33rd move. Black has an obviously winning position, and so it should not be surprising that the has quite a few ways to win or increase his advantage. However, in the game Black played a move that convinced White to immediately resign!  What do you think?

BLACK TO PLAY AND CRUSH!

SOLUTIONS

Reykjavik Open  2016.3.14 Dvirnyy, Danyyil–Hedman, Erik: 20.e5! Qxf4 (What else? White is threatening to win the Queen with Re4) 21.Re4! Bf5 (The whole point is that after the intended 21…Qg5 White has 22.PxP winning material because of the undefended Rook on e8 after the Knight moves.  That is why Black should have played 19…Bd7, in which case White’s little combination would have not worked) 22.Nxf5 Qxf5 23.exd6 Na8 24.Rxe8+ Rxe8 25.Qxf5 gxf5 26.axb5 a5 27.Na4 Be5 28.Re1 f6 29.b6 Rb8 30.d7 Kf7 31.d6 1-0

Reykjavik Open  2016.3.13  Shabalov, Alexander–Gupta, Abhijeet: 33…Nf3+! 0-1 White does not want  to see what will follow: 34.PxN PxP+ 35.Kf1 Rg1+! And 36…Qg5+ or 35.Kh1 Rg2!
