16th ch-EUR Jerusalem 2015.3.6 Position after 16 moves. Black has mishandled the opening and now finds most of his pieces disorganized and far away from his King. This gives White an idea…
WHITE TO PLAY AND WIN MATERIAL!

16th ch-EUR Jerusalem 2015.3.8 Position after White’s 43rd move (43.Qc4) Earlier White missed several wins, but now it seems as though he is winning anyway: If 43…a2 44.QxR! a1(Q) 45.Qb7+ etc or if instead 43…Rb2 44.d5! PxP 45.Bxd5 etc. The Black King is too open.
HOW DOES BLACK SAVE HIMSELF?
16th ch-EUR Jerusalem 2015.3.6 Vovk, Yuri–Howell, David: 17.Nxf7! Ouch! 17… Rxd1+ ( 17…Kxf7? loses quickly after 18.Qh5+ Kg8 19.Bxe6+ Kh8 20.Bf5 etc ) 18.Rxd1 Nc7 19.Nd6 White has a clearly won game, but Howell fought on bravely for another 50 moves or so before throwing in the towel.
16th ch-EUR Jerusalem 2015.3.8 Vallejo Pons, F–Svetushkin, D: 43…Rxg3+!! 44.Kxg3 Qf4+ 45.Kg2 ( 45.Kh3 Qh4+ 46.Kg2 Qg4+ is the game) 42…Qg4+ ( Ofcourse 45…Qxe4+? 46.f3 ) 46.Kh2 Qh5+ White can not reasonably escape the repetition of moves. 47.Kg1 Qd1+ 48.Kh2 Qh5+ 49.Kg3 Qh4+ 50.Kf3 Qf4+ 51.Ke2 Qxe4+ 52.Kd2 Qf4+ 53.Ke1 Qe4+ 54.Kd2 Qf4+ 55.Ke1 Qe4+ 56.Kd2 Qf4+ 57.Ke1 Qe4+ 1/2-1/2
