Weak A flops top pair against semi-large field

[Corkscrew]

No read on CO, unfortunately. First hand at the table. SB was pretty fishy. MP2 had played almost all of the 8 hands he'd had at the table so far, and raised 3 of them (showing down only 88 of these).

I'm pretty satisfied with my aggression on the flop and turn, but I gave in to an overriding urge I get sometimes, that being to check-call the river any time a scare card comes, even if it isn't actually all that scary. In my defense, with no read on the CO I couldn't be sure what he was calling down with.

Comments?

I think I would bet the river, might have made the SB call if CO didnt raise (since he might think "hero has been betting the whole time, he could be bluffing." I have seen people in his place call down with as little as 10 high before)
