A spot that I think I have to play better at.

$300 eff @ 1/3NL
Main V (BTN) has played every hand for 4 hours. Bets almost every flop and calls most raises. Not really a thinking played. For example, called 87o when there was a raise and reraise to $55 preflop etc.

BB: Also loose but plays very straightforward fit or fold.

OTTH:
3 limps, Hero calls SB J8hh, BB checks.
($15) Flop J86cc, H leads $15, BB calls, V raises to $30, Hero ???

BB already has his calling chips out. Should we go for a c/r or lead on the turn? Or go for a 3bet on the flop? And if we decide to go for a 3 bet, what sizing do we choose. I don't necessarily want to let BB in for cheap, but are we ahead significantly enough to just flat call this OOP.

Let him bet the flop and throw in a raise. As played, this board is way too wet to not 3 bet. 3 bet to $120 and look to get it in on the turn.

I like the strategy of leading this flop if the Villain is likely to raise you allowing a 3bet. If he's shown a tendency to call bets on the flop, but not raise then you probably want to check it to him and let him bet so you can get a raise on this flop.

As played, for sure 3 bet, Any size $100+ is good to me and ship pretty much all turns

I'm ok with preflop and it's what I do at the tables. However I will say the more I play the more I have been thinking completing here may be a mistake mainly due to the cost of playing postflop OOP.

With aggrotard Button I might check this super drawy flop to check/raise. Donking PSB is also fine.

I typically have a "don't go broke in a limped pot" rule. The most important distinction to make is exactly what type of maniac this guy is. Is he one that'll see any flop for any amount of money but then only get in bigger stacks with reasonably good hands postflop? Or is he just as splashy loosey goosey gambooley aggrotard postflop?

If he's the type of guy to bet any flop, I'm guessing there's a bunch of hands we can easily be ahead of here (overvalued hand, worse junky two pair, draws, air etc.) so I'm willing to go broke in this limped pot now. I typically like giving poor 2:1 odds for draws, which would mean I would put in $105 at this point. If he calls, that would make the pot $270 with us having a very reasonable shove of $180 for the turn. Dude is a "maniac" so it's unlikely he's getting off the hook to our large raise with anything so let's do this now before the board starts getting stupider / we let in the BB for extreme cheap.

Vs described player I just jam flop. Too many awkward turn cards that you end up not knowing what to do OOP 3 ways. The board is wet enough that you can get called by much worse and he may even call it off with random Jx. V doesn’t sound like the type of person that likes to fold and if he also happens to have 2p he’s never folding
