I'd never check the turn. The deuce didn't help him and clearly isn't going to scare him either.
If he's got a worse two pair he's going to love that card.

VS a typical bad passive 10NL player I'd bet $3.25 on the turn and fold to a shove since they are basically never turning Ace high or QQ-77 into a bluff.

For me a river bet depends on my notes, I don't play zoom not sure whats best against an unknown. I can think of several players that I would check behind and several that I would shove.

I would make flop bet sizing at least 1/2 pot. That sets your villan up for an easier turn call w/ a worse hand w/ SPR way less than 1 on turn. As played still jam turn bc SPR < 1 and of all his combos you only lose to AK which there are like 4 of and 1 combo of KK (I'm assuming he doesn't 3-bet pre with 66), so there are 5 combos that can beat you. I can find 5 combos you are ahead of and that he'll call with in like 5 seconds which means easy shove on turn betting half pot on flop or as played.

First off poker is a extremely complex and difficult game. I ve played too many hands of nlhe and I still spew $$ all over the place. Just gotta keep studying and reviewing and slowly make less mistakes over time.

I m somewhat perplexed by this spot as well. Flop bet is fine and std. Wouldnt size bigger really. Turn I think Dsikesii s idea of small betting and folding is something that would maximize vs player pools that ll never take advantage of the fact that we can be b/f here. Jamming can t be too bad and idk if you can prove which is better OTT.

OTR I like checking tbh. Not impossible for him to check a K and our hand is a lot more faceup here as I doubt you or the player pool is bluffing here nearly enough making it a lot easier for JJ and TT type stuff to find a fold.

Depends a ton on player type. Nits will fold QQ to a jam, fish will struggle to fold AQ/44, so obviously that difference will totally define your value range.
