Sorry, this is a $10+1 tourney. Never played against villain before and no reads since it's the 3rd hand.

this is AJ or AQ or A9 or A6 much more often than its AT or 44. I think if you're making this kind of a laydown without a read (and I'm not saying you are) you are giving the $11 players too much credit.

I've definitely gotten reraised w/ A+weaker kicker on Party. Hell, I've gotten playback from QQ and JJ. I think on PP this is an easy push w/ 3/8 of your chips already in there.

On Stars I worry about AT and TT, but I still push. Anybody more familiar with Stars want to chime in?

I push.

Also, you might want to raise a little less preflop although 5BB at this level isn't bad.

And there's no need to slap 200 out there on the flop. 150 or so is plenty vs. one opponent.

as you all recommended I pushed. Opponent called and turned over A2 offsuit. I won't say what happened because then this turns into a bad beat post. Just wanted to make sure my play was correct and that I had the right idea.
