This thread is exploring the general problem of flopping a vulnerable top-pairish hand, betting and getting called by 3+ people. Assumption is that we bet flop because the players last to act are passive. Also assume loose table, that people raise turns polarized to two-pair type hands (with some turned top pairs)

We have J9 in the sb. 4 people limp, we complete, BB checks.

Flop: 9 6 2
We bet, 3 call.

Question 1: What do people do on the following turn cards?
T
T/T/T
A
A/A/A
K/Q
other kings and queens

Question 2: Instead of 3 people calling, x people call. How big does x have to be before we start checking an offsuit K/Q?

Question 3: What about if the table is aggro? More reason to bet or check?

Question 4: As a general rule, I default to betting nearly everything on the turn with 3 people in with a vulnerable top pair, and reevaluating if raised. At 4 people, I start checking the really bad turn cards, though I feel like I should be checking more on an offsuit turn T. Essentially, I want to know how others determine when c/f becomes more +EV than b/f.

with vulnerable made hands a good plan is to check the flop hoping to checkraise a late position bet. i'm only leading out with strong draws or big made hands

BBB - Lets assume the players last to act are passive and likely won't bet our hand for us. Or, if we c/raise and still get 3+ callers. Do we prefer b/eval or c/c or c/f?

I'd prefer to bet into 4 people rather than hope one of the other players has enough of a piece to bet. No free gutters or over cards imo @ 6/12. You should get more calls than bets on the flop.

I'd bet any non spade, non 6,(maybe not a 2 either if I had a read) on the turn and reevaluate river.

I bet the flop. Hoping that someone bets a worse hand for us so we can check raise is pretty hopeful thinking in a live 6/12 game. Pretty much every turn card sucks and if I can get even one guy to fold, good for me.

I'm betting all turns barring any "tells" or specific player reads.

do you guys regularly have five more people check here if you check first?

Absolutely. But not always, so your probably right. I think its much closer than it seems. The 6/12 games I play in can be very very passive. Lots of players would happily see the turn and check if they miss.

This example seems to be a bit of a paradox as I am not sure what villains are so passive that they check the flop but then bet a polarized range on the turn. I understand that you are trying to create a very specific situation, but I think the chances of it occurring are very slim.

Also, think the flop bet is a mistake. With this many people in the hand the chances of us folding out a better hand are non-existent and the only draws that we are punishing are long shots. Meanwhile our flop equity edge is probably small (at best) given the board texture. I think that we are better off checking the flop and betting a safe turn. I understand that like most of the deck is a scare card to our hand, but that is why we have such a small equity edge. We are better off letting it check through and waiting to donk a safe turn (when our equity is significantly higher with 1 card to come).

Assuming that we get to the turn, after having bet the flop and getting 4 callers, I am c/f every card that you have listed unless I have a specific read on a player. There are just too many players in this hand to think the MPMK is still good.

EDIT: there might be some specific instances where I would c/c a turn bet here. I need to think about it a bit more, but my default on those turn cards is c/f.

Post fixed for clarification.

Typically into a field of 4 with a weak top pair hand, I check and see.
As the hand has played out, I lead all those turns against a field of loose passives.

What is our plan on a river blank if all of the villains call? Are we betting still? c/r? c/c?

If all villians call the turn, I'd check river UI. I'd call one-bet HU if it's a river blank... I'm not overcalling.

I'm betting the turn because at that point I'd say we are still ahead of enough of villains' ranges to bet for value and I don't want to give a 1 card draw a free card.
However, if all 3 call the turn, I'm more inclined to think we are in fact beat (esp if the turn was non-spade A).
