At least now I know how he plays his nuts

If you follow the Baluga theorem you have to fold turn vs the raise with less then top 2p.

Flatting flop and MR the turn is often a nutted line, but whales can do it with a T or pocket 3s or shit like that, so its not that bad.

Just fold the turn against reggish looking players. You are not getting exploited like... ever. You bet kinda big, I would have bet less, but the way you bet should mean that a MR is even stronger because your opponent is more confident you have a hand to pay him off with, so thats a bonus info for you. Good info sizing, but you should be folding against aggression.
Calling for info is second best as long as you exploit him later!

Just stack-off the turn if you think hes a weak player /of which we dont have proof/.
Lets say a fish 99 or Tx and is willing to stackoff OTT but when the A,K,Q,J or a heart comes OTR how are you going to get his stack if he checks? How are you going to find a call/fold with such good odds and such a nutted line?

Just make your life easier!

How I would have played it against the guy who has 0/0 for 11 hands: Bet turn smaller, call the MR to re-evaluate and fold river, because the SPR is bigger. With the bet sizing you made, Im folding the turn, hes kind of transparent and KT, AT actually do not make sense.

I think folding turn would be good.

For the Baluga theorem: you'll find them in this link: Baluga theorem.

I think it is still valid for Micro limits.

Fold on the turn would have been the best play. But at micro stakes, with an on over pair to the board, I completely understand why you called. I probably would have too. But, I would have folded on the river. With his pre flop raise, it wouldn't be unreasonable to put him on a hand like AQ or KQ. Sp once that Q hits, I'd let it go.

Easy turn fold (by any kind of reasoning, Baluga theorem, etc, sophistication not needed, but GTO dictates fold too).
