Villians is unknown, playing 35/15 after a few hands. Do you like a check back on the flop? My Equity versus his checkrasing range on the flop should not be great and I have a great playability on the turn and could induce some bluffs.

As played should I bet the turn for protection? Can I safely bet/fold this turn versus unknown? I allways hate my life if I get raised, because I have most of the time only two pair or a bluff here and feel like I could get exploitet too much if I only stack off with trips+. Do you think bet/gii AAxx and folding Kxxx here is a good play?

If you prefer a check behind, would you call a bet on a 2 river? I don't think people bluff here often, but against unknown or recreationals i am not sure.

I'm bet-3betting flop. As played turn is nasty. He'll have a lot of draws. Sometimes with a 6 in them. He'll have some AK/KQ hands. Probably no full houses. Guess I like betting around 12. Fold to raise. Sometimes in similar spots you might bet likewise, but to induce a shove. But this should be done vs aggro players, and maybe when the turn opens up a flush draw as well as pairs the board, so it makes more sense for him to have semi-bluffs.

This, which is what i'd do with a boat.

....except the folding part

Flop is kind of the interesting part, and you can argue for checking back, but overall i prefer a bet as i'm not really that desperate to see a turn and we have lots of hands to protect against.

pre fine. on the flop good cbet. turn i would like to bet 12-14.50 fold to raise. dont prefer checkbehind. its good balance stuff for hands like aaxx or fh. there are not many fh in his range. 6x could connect with his semidraws on flop.

+1 to everything said
