Hi guys . As i m reviewing my last session i am unsure about this fold . Now i lean towards a call blocking the straight ? The line he takes to me it looks like AA KK ? i ve seen this kind of shitty min raises with these hands at nl2 and i really want to know ur opinion

Stacks:
UTG - Hero ($5.63)
MP - MP ($2.62)
CO - CO ($2.00)
BTN - BTN ($2.15)
SB - SB ($2.00)
BB - BB ($11.13)

Preflop: ($0.03, 6 players) Hero is UTG with Jd Ks
Hero raises to $0.06, MP raises to $0.10, 4 folds, Hero calls $0.04

Flop: 4s 9c Qh ($0.23, 2 players - Hero: $5.53, MP: $2.52)
Hero bets $0.07, MP raises to $0.14, Hero calls $0.07

Turn: Kc ($0.51, 2 players - Hero: $5.39, MP: $2.38)
Hero checks, MP bets $0.48, Hero calls $0.48

River: 4h ($1.47, 2 players - Hero: $4.91, MP: $1.90)
Hero checks, MP bets $1.90 (all-in), 1 fold, Uncalled bet of $1.90 returned to MP

Total Pot: $1.47

MP wins $1.42

That line is so obviously for value on NL2 that I have no idea why you would ever consider calling the river? Min3bet pre, min raise flop, pot turn, overbet all-in river, it's not getting more obvious than that.

You raise a crap hand pre, get 3bet and decide to call, probably because the odds are so good. Then you proceed to donk the flop super small with K-high and a gutshot. That might be a viable option as a total exploit but otherwise is really bad.

On the turn, you have a bluff catcher und there isn't a single hand in his value range that you beat. That's not a spot you want to be. Same on the river.

Fold pre.

About the only good thing you do in this hand is fold the river.

As the 3-bet was a minraise, you can call it, but you should be very careful post-flop, as villain will often have a monster if he starts putting much money in the pot. (i.e. You should be cautious even if you hit top pair)
I'd usually check the flop (and fold to a big bet), but I can see how a small donk-bet can work out well sometimes. Getting minraised means you still have the right implied odds to call once with your gutter, but I think you need to be disciplined and fold to the PSB when you turn top pair. You're not getting the right price to bink a 10, which is almost certainly the only way you'll win this hand, as you're losing to AA, KK, QQ, AK, KQ etc etc.
River fold is mandatory. Don't even think about calling there.
