plo50 facing turn craise by fish

I like the flop bet, only because you have a gutshot to go with the flush draw and if you hit the turn or river you get paid off.

The turn is a lot harder to judge. The main issue is if villain has a set, he can't checkraise the flop with all the money behind so probably has to wait for the turn. If you hadn't hit the queen it would be an easy check back but now you have to think whether you're ahead or not.

The argument for checking is you can snap off any river bet from villain when it blanks plus villain might donk in to your nuts when you hit.

Your bet sizing on the turn pretty much says you don't have a set or even top 2 pair because it's a super wet board and you're not jamming it so villain can easily play back here with Q8 or any set (maybe even Q6).

It's possible he could have a slow played AA or KK and just picked up spades as well on the turn.

Your 3 options are to bet full pot on the turn which discourages light checkraises (and maybe consider puke/folding to the checkraise since it can only come from a set at this point), bet half pot and snap off a checkraise since your bet sizing can induce semi bluffs or check back the turn and snap off all river bets where a spade doesn't hit.

Point is I can't think of many situations where you would bet $6 with your strong hands.
