I think I made some mistakes here and want to hear how ppl would have played differently.
I was new at the table, less than 20 hands. The SB was new too, and Villian so far had raised 1/14, so didn't seem too fishy.

Seat 1: MP1 ($4.49 in chips)
Seat 2: Villian/MP2 ($3.66 in chips)
Seat 3: hero ($4.17 in chips)
Seat 4: CO ($3.47 in chips)
Seat 5: Button ($7.23 in chips)
Seat 6: SB ($6.95 in chips)
Seat 7: BB ($0.77 in chips)
Seat 8: UTG ($5 in chips)
Seat 9: UTG+1 ($3.39 in chips)

Preflop
Dealt to hero [9s 7s]
UTG: folds
UTG+1: folds
MP1: folds
Villian: raises $0.10 to $0.15
hero: calls $0.15
CO: folds
Button: calls $0.15
SB: calls $0.13
BB: folds

FLOP [7d 3d 6h] ($0.62)
SB: checks
Villian: bets $0.15
hero: raises $0.35 to $0.50
Button: folds
SB: calls $0.50
Villian: calls $0.35

TURN [7d 3d 6h] [4s] ($2.06)
SB: checks
Villian: checks
hero: bets $1.15
SB: calls $1.15
Villian: calls $1.15

RIVER [7d 3d 6h 4s] [7h] ($5.36)
SB: checks
Villian: bets $1.86 and is all-in
Hero: ??

Fold pre.

as played, I'm not sure why we're raising the flop. Nothing worse will call us besides combo draws or a flush draw. By the turn, most combo draws complete the straight or have 2 pair, so there is no value in betting the turn. I don't think he's ever bluffing with something like a missed flush draw or has a worse hand by the river, especially when he leads the river after you lead flop and turn.

+1 to fold pre

why fold pre?

It's a crap hand and you are not leveraging great implied odds because you are only 80bb deep. I would rather 3bet this.

EDIT

I don't show great results from overcalling suited 1 gappers. If you are consistently exercising superior post-flop skills to successfully make this +EV, of course that's fine.

haha obviously i'm not. ya I probably should have folded pre.

Yeah fold pre. Calling with a marginal hand after the flop will lead you into tough decisions when you may or may not be ahead. Example as above.

Having said that if you were to call then you hit top pair, well done. That raise is terribly small. The villian bet small almost wanting a raise. It could mean a set or it most likely is an over-pair.

That turn you need to slow down. Alot of draws got there and any hand with a 5 made the straight. K5 hearts even got lucky there.

The fact that you hit your trips on the river puts you in a tough spot. But if you were betting like you were ahead on the turn, then you def are ahead on the river. I reckon you'll see JJ+ here a bit, 66 or 33 as well.

I think it's a call on that river, but you really did make it difficult for yourself.

Fold preflop or 3-bet as a bluff. We're looking for bigger flops than just a top pair with no kicker when we play hands like this but I think raising flop is fine, since his bet sizing seems so weak and we a have outs if our hand isn't the best. I would check turn and fold on all rivers if anybody bet. As played the river is very meh, don't think we're good all that often but we're getting good pot odds, we need to have > 25% equity to make the call. Highly doubt we got that though, we're 3-way on a four straight board with a flush coming in on the river.

3bet or fold pre depending on the profitability of a 3B (If its good, take it. Otherwise just dump the hand)

Flop - Not raising.... Not much worse calls - anything that does, have a sh*t tone of equity against us.

Turn as played, checking back

Riv - As played, prolly calling. Hoping to see some 88+ that v. has also butchered.

That said, this hand is an example of how NOT to play poker Im afraid.

as played, call, u'll see a lot of op here

I just started eliminating cold calling with 1 gappers most of the time and it's actually improved on the their value. Agree, calling with them is not +EV most of the time. I would 3 bet if anything or just fold.
