Checking river here. Very bad card and we have 2 black cards.
Probably a check fold unless we have good info that V is aggro enough to bluff here because does a King really bet here? Everything else you lose to.
Good fold, could've saved a Dorra.

I'd bet nearly pot on the flop and turn against a fishy looking stack size, but agree on checking river.
Alternative to checking given the villain looks a bit fishy might be to bet really small, like 20% and fold to a raise obviously.
This will be a bluff from villain about once a year imo.

Bad advice from ^ imo. You cant only VB flush here. His range should be mostly Kx and that we should try to take value from. Think the fold on the river is fine even if we get a really good price I dont think this is a bluff often enough to make the call.
