Hey chess.com,

Just finished what I thought was a great example of a Colle sacrifice - take a look! (And please point out something that I missed, if I did :x)

nice

After Kg6, I would have played Qg4 with all sorts of nastiness threatened.  Black should have played Re8 after Qh5 and maybe he can hold.  But you still get the better position regardless.  Nice game!

Killabeez, 13...Re8 allows a typical mate: 14.Qxf7+ Kh8 15.Qh5+ Kg8 16.Qh7+ Kf8 17.Qh8+ Ke7 18.Qxg7#. After 12...Kg6 13.Qg4 indeed seems best, and very convincing.

Nice sac, by all appearances completely sound.

One remark about the opening: 4.e4 was too soon. Black could have played 5...e5, when he is in fine shape after 6.dxe5 Qxd1+ 7.Kxd1 Pg4, threatening both Nf2+ and Nxe5. You should have played 4.Nf3 first, which leads to positions similar to those in the game.

Edit: Atomic chicken, you just beat me to it.

atomichicken - Good point about 4. Nf3, I haven't played that before. It just always seemed like gaining time via kicking the knight was a good strategy - I'll play Nf3 the next time I see Nxd5 and see what happens.

I assume pushing the d-pawn after 5. .. e5 is overextending?

Sorry mathijs, I just gave a cursory examination of the board without really calculating.

 Te absolvo. I do that all the time. I just looked a little closer here because I wanted to make the sac work.

12... Kg6 13 Qg4 f5 is critical--Black may be able to survive.  At any rate, it was certainly better than what happened to him!
