I too am a lowly NL50, but I'll never get any wiser unless I practice.

12/5 in the CO, he is still mostly with the premiums, so big aces are like half of his range here. Given that, and the board, a flush seems unlikely and there is only AT or TT for the str8.

Actually we look much more likely for the flush or straight, I think I betfold here for around half the pot, can't see him raising with anything but the best and I'd be too worried about losing value to check call, plenty of 2 pair hands he can have that would just check behind otherwise.

Edit: pokerstoving him with a 10% PFR range (to allow for he is in the cutoff) your villain is a 3/2 dog. So, you can put him on an even wider range and still be fairly happy getting your money in.

Also, if you give villain any credit at all, maybe 1/2 pot bet will look too much like "aha, he is bet fold", so maybe a little more, say 180.
