1). fold

2). agree w/ papal you really should raise this flop - K-x will want to get in too.

3). with $160 already in the pot, as well as the possibility he is doing this with K-Qo, you don't need any fold equity to make felting +EV.

4). as played check/raise all in, your range will definitely contain flush draws and he may call with 9-x. i prefer bet/fold on the turn versus an unknown. check/calling is worse than check/folding.

5). you are only a 3:1 dog versus A-3/A-10, and 3-3/10-10 are the only hands that really dominate you. shove the flop since villain will be about priced in to call with a flush draw. I'm sure people will show up w/ A-Q here too. as played yea that was a bad river for you, check/fold.

without the backdoor straight/flush draws, getting raised on the flop is a lot crappier. Then i would probably call the raise and check/fold the turn.
