Flopped set, runner runner comes

Well I see some worse hands he's raising with: 77, 44, AQ, even AK (fish on NL2 always feel committed to AK) good players wouldn't of course but on NL2 I saw this often...just because of runner runner flush I'd not automaticly fold here. Of course the raise is strong and the fold isn't bad, ut I think it's a little bit too tight here. I'd not love to call here, but I'd call.

I would also call here, chance are very little he call you with a backdoor flush draw I would guess maybe AQ or AQ or even JJ,KK,AA.
and the only straight would be 56 mmmm interesting.

I would definitely bet bigger OTT.
Check/call OTR.

You hit a set OTF, my initial plan would be to go for 3 streets and get the max value. I wouldn't be too afraid of runner runner flush here, especially when the guy opened from UTG and that Ac should block many of his flush combos. Some QcXc hands might make sense but there are not many. He could do this with 77,AQ. River raises are super super strong but I think I still wouldn't be able to fold here. But I still wouldn't say that folding is terrible, considering that in these cases villain so often really has the nuts even though it is unlikely for him to have those.

I would raise flop bigger. I would make bigger bets on all streets.
As played I will call the raise vs my smallish bet on river.

You sized flop and turn perfectly for a river shove, now it's time to jam it in my friend!

Do NOT be afraid of the flush when the ace falls and you are against a guy from an early position
Only flush combos he can have are KcQc, QcJc, QcTc
He can also have all AQ here, and 77 depending on how he plays

-And this is pretty conservative, as the guys mentioned people will call you with surprising things art NL2 all over the place

One of the spots where just following the beginner strategy and not being fancy would help you avoid a really big mistake

OTF check-raise is best,OTT bet bigger, OTR I'll go all-in, Qx will call on this limits,like you play it's call river,imo.
