Analysis of Ng - West

At his Contre Gambit Philidor blog, Frederic Fournier suggests that fear of the PCG explains why Andrew Ng was content to play for a draw against me on Sunday. Fournier gives 16.Qg3 Nh5 17.Qh2 Nxf4 18.Qxf4 Qe7 with compensation for Black. Now 19.Qxc7 Rc8 looks too risky for White. Play would likely have continued 19.O-O-O Rf8, with a roughly equal position.

An interesting queen sacrifice might have occurred after 16.O-O-O when it is too dangerous for Black to play 16...hxg5 17.hxg5+ Nh7 18.g6 Bh6 19.Rxh6 Kg7 20.Rxh7+ Kxg6 21.Rdh1 winning for White. Instead Black should play 16...Bg4 when both White's queen and rook are threatened simultaneously.
