Re: Interesting $109 Bubble Situation
 

I call this, and I think you have to look at the possible stack sizes next hand just as much as the stack sizes this hand. Whether or not the button is pushing any two, there's still a good chance he'll lose to the SB heads up.

Stack sizes supposing sb takes down the pot (and you fold pre):

~3000
~5700
~2400
~2600 (hero)

Since you're posting the sb next hand, you run the risk of being the short stack at the table by folding this hand. Also, your table image is hurt a bit with each fold in the BB.

I think the risk of sb tripling up is much worse than the risk of losing to BOTH the sb AND the button with the sb beating the button.

Results: Interesting $109 Bubble Situation
 

Guess this one wasn't quite as interesting as I thought, though it's a call I'm not sure everyone would make. I'd imagine it's a bit counter-intuitive to some players with the SB all-in.

I took a second to think the situation through and called. Button had 94o, SB had KT and flopped two pair. I held my breath as no 9 hit the turn or the river, took the chip lead, and went on to win the thing as I got to play the role of aggressor after that hand due to the perfect stack sizes at the rest of the table.

BTW, the bold sentence is something multitablers don't do nearly often enough. Sometimes it's OK not to be on autopilot.

Granted the button is probably pushing with any 2 here and the SB is basically pot committed preflop but I just can't bring myself to make this call.

If the SB wasn't AI in front of you or at 1.5xBB I would call this instantly. Also if the blinds were at 400/800 instead of 300/600 or hero didnt have 4.25xBB after posting I would be more inclined to call.

Anybody wanna do an ICM calcultion on this mofo?

Hmmm, I think you have this backwards.

I muck it like it was contaminated by radiation.

I would just be so upset if the button had q3 and the sb had kt and the flop came kq-x and I busted out in 4th.

But it's wrong to make decisions based on, "what if this scenario plays out?".
Right?
I mean, this sounds like justifying limping with XXs, because "if I flop a flush it'll be great".

Re: Interesting $109 Bubble Situation
 

I'm somewhat addicted to looking at these types of 3-way calling situations on the bubble - Gimme more drugs man...

Has the big stack been pushing every hand possible? Let's assume he's pushing close to any two (like top 3/4 or so - maybe he's pushing a wider range, maybe a narrower).

If SB "seems solid," he probably knows the big stack is pushing just about any two, and he's likely to call with even just a decent hand against the big stack pusher (esp. with the overlay present that will be lost after this hand). A lot of SB's will call with a wider range, but let's give him about top 1/4 of hands (any pair, any Ace, KQo-KTo, KQs-K9s, QJs-QTs, JTs, QJo).

88 = 42.0%
Button = 24.3%
SB = 33.7%

So...the only time you finish 4th is when SB wins, and the button also beats your 88 - that's going to be less than 1/2 of 33.7% (maybe 15% - Pokerstove won't figure that out for you exactly). So, taking that 15% assumption:

42%

Hero - 7,200
Button - 3,300
UTG - 3,000

(Note that here alone your expected prize pool equity will be close to 40%)

24.3%

Hero = 3rd place

18.7%

Hero - 4,800
SB - 2,400
Button - 3,300
UTG - 3,000

(ICM gives you about 30% of the prize pool here - though you may do better on average with your new found stealing edge on the bubble...)

15%

Hero = 4th

What's your expectation the times you fold? Given the hand ranges, SB will win about 60% of the time. So...

60%

Hero - 2,600
SB - 2,200
UTG - 3,000
Button - 5,700

(ICM says your expectation is about 20% of the prize pool given these stack sizes above - equivalent to finishing 3rd)

40%

Hero - 2,600
Button - 7,900
UTG - 3,000

(ICM says your expectation is about 28% of the prize pool)

So, by calling, 60% of the time you're the new chipleader (42% of the time by a large margin) in a big blind poker situation - definitely a big edge. For this edge, you give up (.15)(.232) = 3.5% of the prize pool right away (23.2% is your (ICM approx.) expected prize pool equity the times you fold your 88), plus when you call with 88 and are knocked out in 3rd place (Button wins the 3-way pot), you lose (.243)(.032) = .8% - Thus you're giving up about 4.3% of the prize pool in order to be chipleader 60.7% of the time (42% by large margin 3-way, 18.7% by smaller margin on bubble still). Of the times you're chipleader, if that ups your expected prize pool return by an average of greater than 7.1% ((.607)(.71) = 4.3% approx.), then it's probably the right play to call with 88. It's pretty clear that your prize pool expectation goes up way more than 7.1%, blah blah, yada-yada, blah blah...it's probably the right play to call with your 88 (given all the above assumptions, of course).

General Rule for 3-way calling of all chips on bubble with an all-in shorty already in the pot - When...

(a) The blinds are relatively big;
(b) The big stack is pushing just about any two;
(c) The short stack who calls in front of you is calling a non-tight range (doesn't mean a premium hand);
(d) You're hand is a good favorite against the big stack's likely range of hands, and probably at least on par with the short stack; then....

Folding is almost always incorrect in a 50/30/20 payout structure.

It does totally suck the few times you call and get knocked out, but if you're playing to make the best $EV plays, then calling is almost always correct in these spots.

I put the big stack on precisely any two cards. I think this was the fourth hand in a row or so he had pushed. He was doing was he should be doing - playing stacks and situations.

Thanks for the excellent analysis, Gramps... I'm about to look at it a little more closely.
