Black has put himself in a very difficult position, but certainly not impossible. White's attack is strong but probably not perfect-- I think Black can get quite a bit of freedom at the cost of one of his (many) useless pieces. 18...Bxg5!? 19.fxg5 Qxg5+ 20.Kh1 gives Black some chances; perhaps with 20...f5! to block out White's light-squared Bishop. 18...Nxg5 19.fxg5 Bxg5 deserves consideration as well, I think.

...sure it wasnt lost for black and the only exitwas a sacrifice...but this is blitz and just a few time to think about it !

Certainly not; this loses at once.

Great game!
