In the first hand above, what was your thinking when you shoved? Were you thinking I am hoping to take the pot right here? Or were you thinking he was a weak player and would call you (more of a value bet?). I struggle with this, I would have thought I don't want to shove because only a player who beats me can call.

He initially raise PF, if it were me he would have hit his set with QQ, TT or JJ.
