Flush river action

[JMa]

Party 5/10 SH. Effective stack is $1k.

I make it $40 UTG with 8h7h. CO calls, rest fold.

Flop is Kh 8c 5h. I pot it, He calls.

Turn is Td. I check here. I want him to bet a mediocre hand here like JJ / KQ / KJ so I can check-raise off it. If he checks behind I still have a bunch of outs to catch. He checks.

River is 3h, completing my flush. I lead for $200 (pot is $287). He moves in, I call.
