"read on him looks fairly confident/nervous"

"Nervous about getting his aces cracked "ldo
So not confident then?
anyway I made it 1200 to go and b&b passed!
Villain now 4 bets to 3600! I stared him down for minute this is when he looked confident but at the same time he was a bit twitchy/fiddly!
I asked him if he would show if I folded? He replied confidently "to you I will show"
I now know I'm behind and fold and he shows QQ
I knew after I shud of taken a flop to try and set mine!
Only way I make a lot of chips is if the flop comes jack high! If the flop comes 10 high I might go broke/lose more chips than my 3 bet! Or I could of got away cheeply if flop comes ace or king high!
