Mea Culpa

It seems my last post on the Queen's Indian Euwe contained a mistake as pointed out by Maximilien from France.

I indicated that white gets a confortable play after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 e6 6.Bg5 Be7 7.Bd3 0-0 8.0-0 b6 9.Qe1 Bb7 10.Qh4 h5 (diagram) 11.Bxf6

White is indeed better after 11...Bxf6 12.Qxh5 g6 13.Bxg6 fxg6 14.Qxg6+ Kh8 15.d5 (diagram)

a/ 15...exd5 16.Qh5+ Kg8 17.Qg4+ Kh8 18.Nh4 (++)

b/ 15...Bxd5 16.Qh5+ Kg8 17.Qg4+ Bg7 18.Ng5 (++)

c/ 15...Qe8 16.Qh6+ Kg8 17.Ng5 (++)

d/ 15...Qe7 16.Ng5 (=)

So is seems i missed black's best continuation 15..Qe7 and 11.Rad1 is the only move that gives white an advantage.
