NL10 - Full HOuse bad spot

Pre go bigger to like 7-8bb when 100bb effective with fish and with the guy in the bu. The fish will continue to often and Bu gets then great odds to continue very wide we want to get the fish heads up.
Flop i like your sizing choice multiway but heads up i would choose smaller so 25-33% because fish tend to react to aggro vs small cbets ip in 3b pots so its a great size to induce random spews.
Turn i dont realy like the check because i see the danger of him having a Q and you check calling turn and river when flush completes you check and he can find nitty check backs which is disaster for us.
I also dont want to bet big turn because we dont need much protection and want to keep his KJ type hands in obviously so best option here is then to block small yourself.
You will still get at least a call from KJ type hands but i think more often they read into your size weakness and you will see alot of spewy plays vs it same concept like on the flop.
Also when you block and he start now raising KJ you can get a much bigger pot from him bluffing that hands then just by him stabing vs a check 50% and river 50% so you end up winning more vs his bluffs and vs his trips.
When the front door flush gets there i would probably just donk out all in to just get the maximum from his Qx and i dont care anymore about the bluffs sometimes you can even see super weird call downs like low pockets or king high when the fish starts leveling himself.
