In this complicated position, Black could not find the only way to win the game.

Iraqi Fide master made a wrong decision.
16. Qg4!+ Kh8 17. dxe5 Nd7 18. O-O +- White would be better in view of Black's weak king position and his passive pieces.

Black grabes his chance to launch an attack on the kingside.
11.Bg3 h5!

Needing to win this game to clinch first place in the tournament I gave serious consideration to 17 Rad1, 17 Rfe1 and 17 f4. However, I'm very glad that in the end after much consideration I opted for (Ward):
17.Rae1! g5 18.Bg3 Nfd5 19.f4! gxf4 20.Bxf4 Nxf4 21.Qxf4 Ke8 22.Nxf7 Kd7 23.Ne5+
and Black resigned.

and Black resigned.
