This hand seems fairly standard, but I suck.

A few questions:
1) Is it standard for SB to cap with 237 or 234 or whatever he might have? Maybe a couple of dead deuces since I don't have one. I would assume those hands are favorites over mine, but still seems weird to cap and then draw 2 to me
2) Should I raise after first draw?
3) Does it pay to valuebet river?

I don't have much 2-7 experience, but I don't think you should 3bet 3468 vs UTG raise. I'd like to hear better players thoughts about SB's cap, I wouldn't do it either, unless he knows you (and possibly UTG) are often drawing rough and likes his good 2-card draw 3-handed. I see no point in raising after first draw. I guess the last street bet depends on whether they think you can snow or not.

1) no
2) no, but SB should checkraise
3) easy bet. i'd bet 875 on the end.

capping a very good 2 card draw isnt awfull but probably a bit spewy at the nitfest that is 2/4.

At 2/4 you might get called by a 9 or even a T here so I would try and vbet.

FWIWs I think 3betting predraw is standard. If I just call I let other players in. I would always 3bet any hand I wanted to play there. Of course, I may be wrong

Sounds quite logical, thanks for the insight. Looking forward to seeing more standard spots where I'm besides the point (actually I'd fold pre here, would that be too tight ?).

This hand does well HU. If we can get it HU with position against UTG I definitely want to play it. If you're in the blinds and there is a lot of action in front I would muck it

3betting a 1 card 86 draw seems okay as long as you have a 3 or a 2 in your hand. Both of your opponents made some pretty bad mistakes in this hand. In the future look to raise SB when he bets a card behind. Also ruthlessly valuebet UTG going into the last draw since hes capable of drawing 2.

Valuebet this river everytime.

you played this hand well -- i would go ahead and vb the riv

sb cap is bad, your line is good, don't raise after the first draw, bet the river.

SB should definitely not be capping here with even 2-3-4 or 2-3-7, let alone any other 2 card draw.

Yeah, I'm not crazy about 3-betting a draw to a rough 8 pre-draw, especially since we don't even have a 2. Although I don't really like calling or folding either. Yucky spot.

I think river is a bet, too, as 8-7 is probably going to pay off, as long as there is very little chance of being bluff-raised.

So you would bet fold the river. Id love to get bluff raised here cos no way im folding

You are a huge nit. I wouldn't call this 8 draw rough, and why does it matter so much if I have 2? I don't really have to break an 87 that often for it to be that important. I am certain this hand is a winner in position.

Do you only smoothcall your one card draws? If not you should probably cap preflop unless you think your opponents are terrible.

On the innanet you can only make it 4 bets

Wow I always miss that in hands.

1) No, SB should just be calling unless you are a maniac who raises the button a lot. Even then he should just flat call to encourage UTG to call.
2) No
3) I would vbet river.

only thing I'd do different is vbetting the river.

You value bet the river their everytime?
