New development in the Euwe defense

For years, I was wondering what was the best continuation against a line in the Euwe defense.
After 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf5 5.Nxf3 e6 6.Bg5 Be7 7.Bd3 00 8.00 Nbd7 9.Qe1 h6 10.Qh4.
Black's only defense now is 10...Re8 as it allows for the bishop to come to the defense.

I have been puzzled by this position, but using a silicon assistant I found a continuation that seems to give white the advantage : 11.Bxh6 gxh6 12.Ne5 !!

The idea is to give room for the white rook. 12...Bf8 13.Rf3 and now
a/ 13...Bg7 14.Rg3 and black has nothing better than to give back the piece with 14...Ne4 15.Qxe4 f5 16.Qe3 Nxe5 17.dxe5 with an obvious development advantage for white, eg 17...Kh7 18.Rad1

b/ 13...Qe7 14.Rg3+ winning easily, eg 14...Kh8 15.Rf1

c/ 13...Nxe5 14.dxe5 winning, eg 14...Nh7 15.Rg3+ Bg7 16.Qxh6

Of course, black does not have to be so cooperative and improve his play, eg on move 9 - but we'll cover that in a next blog.

Stay tuned !
