I am at a super active table and am card dead and am having trouble finding spots.

1) If it got folded to me I was going to ship my 15bb’s from co with my A8o

2) I feel that I am slightly ahead of the short stacks shove range but
I really don’t know how to factor in the 3 stacks behind me.

What is the bottom of your range for isolating here and why???

thoughts??

Poker Stars $20+$2 No Limit Hold’em Tournament – t1250/t2500 Blinds + t250 – 8 players

SB: t210483 M = 36.61

BB: t28044 M = 4.88

UTG: t49676 M = 8.64

UTG+1: t16838 M = 2.93

MP1: t45185 M = 7.86

MP2: t38763 M = 6.74

Hero (CO): t37518 M = 6.52

BTN: t42290 M = 7.35

Pre Flop: (t5750) Hero is CO with A 8

1 fold, UTG+1 raises to t16588 all in, 2 folds, [color=red]Hero raises to t37268 all in

My assumption here is that if you isolate, the three to act behind you will need strong hands to call.  The SB could potentially call you light as he has a huge stack but the other two need 99+,AJs+,AQo+ which is 5.4~ of hands.  I think the SB can be a bit lighter, but not hugely.  77+,ATs+,AJo+ which is  7.5% of hands.  It’s not precisely correct to add them together but you can get a decent approximation of how often you ar are called by adding the percentages  so you get called like 15% – 18% of the time.

 

The rest of the time you are flipping against the range I would put him on

 

 

equity win tie      pots won pots tied
Hand 0: 48.971%   44.57% 04.40%    3132247968 309059256.00   { A8o }
Hand 1: 51.029%   46.63% 04.40%    3276929136 309059256.00   { 22+, A2s+, K6s+, Q9s+, J9s+, T8s+, 98s, A2o+, K9o+, QTo+ }

If these are correct then I would fold (because the equity you lose to the other guys) which actually surprised me.

Of course it’s all read/player dependent so what ranges we assign to these guys is the most important thing.

Wow…when I ran the numbers those are pretty much the exact same ranges that I came up with both for the shorty shove and the three players behind.  Without completly going into the math I would guess that if I was closing the action by calling the shove I would need about 43% equity vs the short stacks shove to make a profitible call witht all of the dead money in the pot.  So if this was cut and dry hu I could call here easily.

 

The problem lies with the three players behind.  I am pretty sure that (1- .054) x (1- .054) x 1(- .054) is the correct way to figure out the percentage of time that you will get called overall by one of the three.  This comes out to roughly 15.5%.  And when I am called here I am obv crushed.  Poker stove is still doing its thing against these two ranges but it looks like I will be about 19% three way if called.

 

Roughly running the math it looks like when no one calls behind my stack ev for the play will be about 40k.

And when some one does call my stack ev willl be about 18k.

 

(40k x .85 = 34k) + (18k x .15 = 2.7k) = 36.7k

 

This is below my starting stack of 37.5k so it looks like my call is negative ev.

 

It looks like I was maybe one pip off and the bottom of my range should have been something like A9o, A7x and 44+ here (I would think 66 initially but the smaller pairs have much more equity than A8o if the pot happens to go 3-way)

 

That being said I had really been blinding down in this and my new focus has been to always remain relevant in the tournament and to go out swinining not looking so I don’t mind the very slightly negative ev gamble here to get to a stack where I have many more options to play.

the only thing I have to add is that it’s pretty important to take in to account how UTG+1 got so short.  If he’s just nitted down to that stack then it’s a pretty turboed fold with the A8, whereas if he just lost a flip or whatever then there’s the tilt factor that widens his range for shoving all 6 of them bb’s in.

This is a very good point and something a friend of mine also brought to my attention.  This tournament had a brutally long bubble with about 10 stacks on the dead money bubble between 8-12bb.  The bigger stacks were exploiting this and he really didn’t seems to have many spots at all.  I did see him shove when folded to him in a couple of spots where I was thinking he should shove very wide before the hand so I deemed this player as competant and put him on a standard thinking players range.

 

Very good point though….obv if he is nitting it up and has no idea of push/fold ranges I need to fold this in a heartbeat.
