2-5 line check

I think I would just call turn here because there is only $285 behind so I know I can easily get all of the money in on a clean river. Raising can't be bad though.

You should not worry about being over-flushed at this stack depth. If I raised turn and Villain went All-in, I would call.

Pre-flop, I think I would raise myself to isolate the limper. I don't hate overlimping though and, if I overlimped, I wouldn't fold facing this tiny raise size from SB.

400 stack is bad.

Preflop: Fold the first time, fold the second time. Even with 800 and a lot of reads it wouldn't be great, but putting in 5% of your stack with 5 high what good things do you expect to happen?

Flop: Maybe even fold now, all your outs are garbage (T9 is possible and a 7 hits you both). Maybe raise is better than call, but like just don't be here.

Turn: 65+40+40 = 145, again T9 got there as did QJ and maybe even stuff like KcJx (would normally be a loose raise from SB, but then you called with 5 high). You probably have to raise here and you should probably shove. Even if you raise to a bad small size like 110, you can't fold without god like reads. If you raise to say 155 and get called you are setting yourself up for bad spots on the river where you have less than half pot left.

I think you must not be paying attention to the board and what I have.

QJ got there? 10 9 got there? I hit a flush on the turn so a straight is losing to me, 2 pair is losing to me.

Sigh. It takes a significant amount of time to respond, so it'd be nice if you thought about it a bit more than just stopping at "Oh, I guess he didn't read the board/cards". Esp. when I said you should shove turn.

You are HU on the turn, you both have ranges. You want to have the best hand when you put more money in and get called, therefore you need V to have worse hands that can call.
This is very significant in comparison to a board like Kc72c3c where the only draw on the flop is the flush and that got there.
Even Jx8c6c2c is much worse for you because not only will V have much fewer good 2nd best hands, but your value range is also smaller and he should probably fold 66.

From a theory POV SB shouldn't just blast cbet 2/3 pot with many hands into limp/callers on J high boards (probably range check in theory), esp. so on J86 two tone which is super wet. Then he is still betting (although 1/3 now) on the Q turn which is an overcard + obvious two pair + straight card + flush card. So V kind of has to be an idiot, be blasting into calling stations as an exploit, or always have a big draw/hand.

I would have limped or raised PF. Surprised some people hate playing that on the BTN so much, although you can argue the way this played out shows why it’s a weaker hand than people think.

I would have folded after the raise to 20 though with a 400 stack. Maybe a little tight but I don’t want to be calling a raise with this hand; I would want to get in cheap or be the one raising myself.

If you do fold PF make sure nobody sees because some people will think you’re a huge nit for folding there.

Postflop is tough. Looks like on both streets you can argue for calling or raising. I probably call the turn because not shoving can put you in some awkward spots and what are you getting called by if you shove? But then again maybe raising is still better so I’m not sure.

What’s the weakest suited connector you guys play there? 76s? 87s? Something else?

Overlimping the BTN after one limper is just bad. Just today I raised two limpers from the BTN with 97s.

It's pretty rare for me to overlimp from anywhere.
