V is really tight, I him on a top pair/ qq+ 95% of the time. Sample size of 700~ and he's played 10% of hands so I played a little more lose it was checked to me.

I'm betting the flop to try and get value from any flush draws.
As played I'd raise the turn for the same reason

If you wound up losing to a higher flopped flush in a blind vs blind battle then that's a bit of a cooler. The way the hand played out though it's hard to think what villain could have the shoved the river with that wasn't a flush. If you fold to his shove you're down 23bbs. If you call you're effectively betting an additional 121bbs that he's doing this with something like a set, a lower flush or even say the busted nut flush draw. Given that he's a nit that's probably not a good proposition. Having said all of that though in the heat of the moment I'd probably end up calling myself.

Yeah it was also a flopped flush, AJc, he milked me and I put him on AA/KK, especially after he checked the flop. I suppose I could have tried to control the pot by bettering the flop, he would have flatted me then raised the turn but I think I would have shipped as I would have put him on KK and then lost anyways.

Edit : I put the wrong title, I put him on AA so widened up is what I meant lol!

If the guy is very tight You should bet out on him , You should be very agressive towards them PRE and especially on flop when the pot is small. He's going to fold all crap hands and even medium strenght hands.

If the guy is a 10% NIT, river all ins are always NUT or close. They only survive holdem poker cos ppl like You pay them off, calling their all ins.

Don't feed the NITS
