Hero ???
Should i bet the River as well like a blocking bet against a potential bluff / shove if i check?
I'm thinking something like 30% of the pot, since if he has it that he'll show anyway but i'm losing less and stop his bluffing opportunity while making my life easier.
In addition i don't expect him to have a Flush on the River much of the time, since Flop didn't contained a flush draw.
It's OK reasoning to bet small here? What you would do?
