I have a few very aggressive hands from today where I might have pushed my opponent off a winner.

Hand 1. I usually call this flop 3-bet.

Hand 2: This Blind defense I'm questioning a bit. Reason is that this player plays taggish however way too aggressive. stats are 21/16/4,75..!!
I'm almost always checkraising when I'm continuing beyond the flop in blind defense plays. However against this guy without at least an a high-hand it might backfire if he makes it 3 I'm pretty lost even if I hit on turn.
