Hmm............................................
I dunno

He was thinking quite a bit before checking. I dunno if I should check behind here ever, and I dont know if I should be calling the check raise.

I guess arguments for calling is
1) I'm in position with top pair and a good draw
2) He might be full of shit/have just the ace high flushdraw.

Arguments against calling:

If flushcard comes and he has AsXx it will be ugly -_-

i think jamming here is the strongest play. in general, calling with position like this is to get value out of a strong hand (like AQ on a K64 board or something). your hand strength relies primarily on the value of the draw (2 pair/trips/flush), so hamming provides you with the fold equity you need.

plus jamming is good for image, and he might call w/ naked As! ^^;

We're 160 bb deep tho, still ez jam? >.< Also fishy timing on the check raise and check, but I guess he could just play that way.
