slaying the dragon?



Interesting game and I was definetely impressed by the moves towards the end of the game. But just wondering, was there really wany point in black's move 18. ... Qb4? 

Also, what was the time controls for this game? I didn't expect an 1880 rated player to miss the checkmate threat. Was it a 1 minute bullet game? 


16...Qb7 looks like a useless move. 16...Qa5 or 16...Qa6 are certainly more principled.


i agree.....Qb7 was useless....maybe queen along a-file would have been better....


@pfren then what would  be the ideal way to continue the attack? (for black)
