Well you have a flush, and he either has one or doesn't.

Basically he looks to be a spazzy fish and flush over flush is rare enough so I'd just call as stuff like this tends to be a bluff vs this type of guy.

TBH I'd just go and raise the turn as soon as I hit it. When I have a smaller flush like this, I want to get value against other hands that might include high cards chasing the flush or also straights here, no need to call and have a 4th club mess up your and strength and also potentially destroy your action/value.

I mean our flush is vulnerable and he's a fish so get some money in there on the turn. He seems the type that would have shipped turn anyway if you raised.

GL!

I'm raising this turn against this player type. He's never folding an overpair or a high club. We should be looking to get all the chips in here versus what looks like a terrible player.

As played I'm still calling this off happily enough knowing that he's probably badenough to over value sets and two pair hands.
