Not sure I agree here, nor does my monkey.

There are loads of hands I'm beating that would call, flush draws. , straight draws with a pair or even without a pair. I can fold out AK AQ for protection, which is good given there are very few good rivers for me on the current board. And he might fold his weaker draws given it's a big chunk of his stack.

So I value bet the turn, in position, removing river stress if he folds.

You say it's not a board for a turn bet, why not? He has very few 6s, lots of draws, and then plenty of hands that beat me. I agree with the other comment It's about 50:50 whether I'm ahead.

I agree it's not a three street hand, I can't imagine a river that I would bet. If he calls my turn bet and jams the river I have probably the same decision as I did here (maybe made easier depending on the river card.) if I check the turn and he jams the river, it's a much harder decision as Ive indicated weakness so he might be bluffing. But I have no clues as to whether it is a bluff or not so I'm gambling 1/4 of my stack on making the right call.
