This spot came up last night and it happens quite often (not necessarily with the short stack all in but in general). It is basically a situation where I have an overpair, or perhaps top pair top kicker with nothing else (which I think is an even better situation in some cases) against 1-3 opponents on a board that doesn't hit ranges very hard.

Example from last night:

1/2/5 Omaha Hi, V1 is on tilt and playing overaggressive. V2 is a massive fish who calls super wide pre. V3 is an absurdly passive nit. C2 has 120, H has 1000 and both other Vs cover.

Straddle to 15, V2 calls, another caller, H raises As3cAhTh to 80. V3 calls (he always has a big overpair or a big wrap here. V1 jams $120. V2 calls. H calls. V3 calls.

Flop ~515

4d5d5h

V2 checks to H.

I feel like I should generally be betting in this spot when checked to against Vs who will not play back at me with draws on a paired board to fold out hands with significant equity such as raggedy non-nut flush draws and gutshots. However, doingthe math it seems like (not accounting for range card removal) one of these Vs will have a 5 almost 50% of the time. I don't think I'm folding out enough equity, especially with V1 all in, to justify betting here. Thoughts on this?

What about if V1 is not all in and just called preflop and checked?

Preflop make it $65 so when V1 jams, the action is open

I'm leaning towards a check in general but in this set up with these players betting small like 150 should be profitable.

Shouldn't it be $60? Or am I missing something, can someone explain?

Straddle is to $15 and Villian has $120 in his stack so $105 difference. Online you could raises $52.5 more but since it is live you can go $50 + $15= $65.

What turn action do you predict if the flop is checked through? Calculating the value of betting isn't enough. You have to compare it to the alternative.

Whether V1 has a 5 is irrelevant because he is all-in and a bet doesn't spew money if he has trips and doesn't fold out his equity when he has a draw. V3 seems unlikely to have a 5 and giving him a free card is unlikely to hurt. So, it seems like a question of whether it is better to check or bet against V2's range.

If he is thinking what I was thinking I think he meant to open action again doesn't villain's raise all in have to be a minimum raise of our open (i.e. $65+65 = 130) which is greater than the opponents remaining stack.

Quick online search says there are 2 rules - full bet or half bet. In full bet the above is the case as long as no other players reopen betting with a full raise. In half bet the raise size only has to be half the normal raise size to open betting again without a 3rd player raising.

Half the raise reopening the betting is usually the rule in fixed limit poker, while 100% of the raise size reopening the betting is the rule in big bet poker.

Thanks! Just not something I think about normally.

I really like the suggestion to bet around 1/3 pot. I feel like that should generally work very well in these spots.

In response to the post about what happens when I check, I think it will sometimes check around until the river and I will win at showdown, sometimes it'll check around and I'll lose. Sometimes by checking I'll incentivize a bet on the turn (which I'll have to fold to) from hands that would have just called the flop, and checked the turn and river unimproved. Those hands, and even more so gutshots, pairs, and bare small flush draws are what I'm targeting with a bet.

Bet like $120 here. Fold to a raise.

Don't see a strong case for betting flop.

+1 to sizing so you can 4bet the short stack's shove, you really f'd this one up badly pre

I'm kind of allergic to betting that small.

Against these two villains I think the flop is a bet. Nit hasn't hit that flop so I just wouldn't worry about him. Loose fish obviously could have hit that flop but will probably give you action with a wide range.

Plus if you check you are inviting bluffs or value bets from worse hands and putting yourself in a tricky spot on non-A/5 turns.

Bet the flop, 150-250 looks good, not sure whether we are calling or folding vs a jam from 'superfish, but against the nit it should be fine

Bet small for value and to fold out equity imo
