better?

ok, hopefully this hand is a little better than that last one. I have two questions about this hand. well, ok, one question was is my flop raise too small/do you play the flop differently. then my next two are.

1. what do you do if this is your first hand at the table and you have no reads?
2. what do you do if you know this guy is pathetic (like, 75/30 preflop)

Wahoo2006 ?

Ironically, the more pathetic (loose) he is, the worse off that turn K is. I kinda doubt he calls your flop re-raise and then donks you with QQ JJ QJ AT.

Not sure you can fold here though. I would definitly not raise.

i would usually push over his raise, or call and get it on turn. i dont 3 bet much without going allin though.
