He had no position to push here i feel, UTG+2. Chances are he could have road the nextorbit of blinds and still been at 1500 chips, and maybe make a stronger play from the other side of the button. You're small stack at the table and they expect you to push any decent two. Anyone with a decent hand will try as well. Villian was a little desperate himself I'm sure and figured he had a fair hand as well. you did get in with the better hand but your looking to double up not go bust at this time. your only in the second hour and people are still dropping like flies. I'd try to be a bit more patient, if you feel you are in push/fold mode you have time. 1200, 1500, 1800 is all the same 1.5 hours in at level6. You need to double up more than once in the next half hour or so anyway. Pick your spot more carefully.
