Now, I completely agree that this definitely should have been a fold. What I am still not completely sure on was at which point it became a fold.

I am thinking that it should have been a fold after the second player went all-in, as the first player, being shortstacked could be trying to push me off of my bet, as I had been pushing him around/stealing his blind for the past few rounds. Am I thinking right in this, as KQs is a decent hand in its own right, against a player that may or may not have any real strength himself? Am I wrong in thinking this, or should this have been a fold after the first player went all in?
