Marcel Duchamp’s hands, New York City, 1959-60/ Alexander Liberman /sc

im  Shen, Victor C  (2394)

gm  Hernandez Carmenate, Holden

24th Chicago Open  2015.5.23  Position before Black’s 28th move. Ofcourse, the Cuban grandmaster saw the …Nf3+, but was confident that Black did not have more than a perpetual check.

BLACK TO PLAY AND CRUSH!

Krishnan, Varun  (2270)

gm  Holt, Conrad

24th Chicago Open  2015.5.21  Position after 26 moves of play. Also, like the previous example, an easy one IF you see the winning idea (otherwise…)

WHITE TO PLAY AND CRUSH!

gm  Danielsen, Henrik

gm  Stefansson, Hannes

ch-ISL  Reykjavik 2015.5.24  Position after Black’s 15th move (15…Nf8?!), trying to get rid of the annoying Knight on g6.  Black had calculated that neither 16.NxB+ QxN nor 16.PxP Nxg6 17.PxN Bxf6 was worrisome.  But he overlooked a clever third possibility…

WHITE TO PLAY AND GET A BIG EDGE!

24th Chicago Open  2015.5.23  Hernandez Carmenate, Holden–Shen, Victor C:  28…Nf3+ 29.Kf1 Nd2+ 0-1  There is a nasty …Qh1+ picking up the Queen

24th Chicago Open  2015.5.21 Holt, Conrad–Krishnan, Varun: 27.Be6!!  1-0  Black can not take the Rook because of mate on f7.  The best Black can do is ‘only’ lose a Rook…so he threw in the towel.

ch-ISL  Reykjavik 2015.5.24   Stefansson, Hannes–Danielsen, Henrik: 16.Nxe5! A clever little move that is easy to overlook! 16…dxe5 17.dxe5 Be6 18.exf6 Bxf6 19.Bf4 with a clear extra pawn, which Hannes used to win the game handily
