villain is very weak/loose, easy jam? he snap called flop

If he usually checks the flush, check behind him. If he usually bets the flush, put him all-in.

Yes of course easy shove.

What is the shove getting value from or reprsenting? This seems like one of those counter-intuitive plays i wouldn't have made but giving Twisted the credit of knowing what is best, probably has merit.
Villain is also very passive from these insignificant stats.

He's a fish and effective stacks are < pot. He can call with any pocket pair containing a club and shit like JTo.

Yeah, even giving him a whole lote of flushes with the Qc Kc Ac draws we are way ahead

He had a flush obv

60 40 is more of a flip than being ahead imo.

Not really neccessary to make a range analysis against a random fish with a small stack. He can show up with anything here. Shouldnt doubt yourself that shove is the right move.
