17...Rxg5 18.fxg4 Bxh2+ looks crushing (19.Kxh2 would be responded by 19...Nxg4+ winning the queen). I guess it is time to resign soon.
1.e4 f5 : me and my oversized ego vs all of you
So you are claiming credit for the idea that engines are stronger than Irontiger?
As obscure claims to fame go, that one is perhaps not the most convincing.
Props to Irontiger for having a go, though. Particularly in so public a fashion.
Resign now would be the way to go. Unless the engine drivers in the thread fancy seeing the thing through to its conclusion?
(deep sea diving a better option, though)

The new Chess King, Stockfish 5 x64 @38 ply likes Rxg5 as well. -2.89. Advantage black!
Fun Fact: It narrowly prefers 13...h6 (there's a 0.03 difference)

Face it, he is facing more than one of the top computers. This was all just a chance to create a fun thread, and he did that. Kudos to him.

I guess he played too risky lines.
Are you implying you could beat the silicon monsters given the same position? I'm in, if you want to give it a try!
We only have to add 13...h6 and you got yourself a new game.

Huh oops, g5 was hanging. Somehow forgot about it.
Well, considering the awfulness that awaits (18.fxg4 Nxg4 is already promising a lot of endgame pain, and of course the computer could find even better), I guess I can just resign here and swallow my pride. Black wins ! Thanks for having played !
Yes, thanks to Irontiger and to those who ran the engines.
Following the approach of the programmes move by move gave some insight into their power. We use intuition to come up with candidate moves but that process necessarily misses a host of stuff which painstaking analysis brings to light.
Playing against them is like walking a tightrope.
Well, that was interesting while it lasted.
