At NL10 I'd consider checking in hand 2 because cbetting has to be -EV against donks that are way too loose. If you get pushed off your hand by a worse one, you only folded ace-high.

But that flop hit his range super-hard. He's calling you with these high connected cards and mid pps. I don't think he's going away with 78 or 99 here.

Now if you had an overpair, that would be all the more reason to bet this flop.
