Turn is an interesting card. I think I like leading and putting pressure on his one-pair hands, although check/raise is also a viable option.
However I don't like to invest that much especially since villain bets turn his range should be more prepared for a check/raise. All things considered I still like check/raise AND leading.

I know leading is weird and I would never lead a flush here but as long as he doesn't know it doesn't matter imo.
The question is do we barrel if the river blanks and I would actually barrel at 25NL or higher but at 5NL.... I mean it's pretty obvious he has onepair or a weak twopair. if he calls my lead..And I don't think he folds that to a big riverbet because people make bad calls especially at 6max.

So what's your opinion? Lead or check/raise?
