White threw it away with a bizarre sac
Cool game

I actually thought that was a pretty neat tactic. Way too gutsy for my taste, but saccing his knight to make castling impossible and giving himself a pawn majority.
I believe what threw it away was the series of unsolid defensive moves afterward. However, I still think it was cool :).

Hmm. This is very wild play. Way too early to start attack with no logical grounding. It is not immediately losing, but Ng5 makes equalising for Black quite simple as White will lose time with the Knight or just end up with game losing material deficit. There are no lasting tactics to support such a move because there is no development.
Guys what do you think of the following game?
