The All-In on the Bubble

First, the initial situation: We play sit-and-go with 9 participants and is precise to the Bubble. The blinds are now quite high and the players have 6.7 to 16.7 big blinds in the stack. The first two players fold and the big stack in the small blind go all-in.

Poker Brainstorm Pre flop: UTG folds, BU folds, SB raises all-in among the players: The Short Stack UTG is a relatively weak player all other rock solid. The big stack in the small blind is very aggressive in such a blind-versus-blind situation and we can assume that he here with around 80% of its range goes all-in. We want to know which hands the player in the big blind should all-in call now:

  • Case 1: good pair
  • Case 2: Very good high cards
  • Case 3: Good high cards
  • Case 4: Moderate high cards
  • General: With the percentage of its range of big blind, should the All-In call

Before I get to the resolution, a note: If the question is undermined me very stupid mistake. The question I had already expected by the second structure in the head and so. A structure as given here distorts the result nice because the increased prize money for 1st and 2nd place create it more lucrative to call something risky on the bubble.

Resolution

The magic word here is ICM and thus it is indeed likely to resolve the hand more or less accurately. Say. You can say exactly. Yes, with this or that hand is a call correctly, with and be wrong. ICM is an abbreviation for Independent Chip Model and very robust agent tournament situations and assess the value of chips correctly. Some time ago, I explained how ICM works and why you need it.

Therefore, we expect that hand by simply. Three scenarios may occur:

  • The big blind folds
  • The big blind and wins
  • The big blind and loses

Now we have to look at just how a lot of chips the big blind in any case, and what value these chips by ICM have. For last one can simply our ICM calculator take? The following Table I the possible chip counts for the three scenarios are summarized. In parentheses is each ICM value of chips given.

What are the hands?

With a good equity calculator, you can no trouble figure out which hands next to the range from the small blind top 80% of hands have at least 58% Equity: If we count these hands together, we come to 194 combinations. Overall, 1,326 combinations are possible before the flop. Say, about 15% of the Range of the big blind, the all-in call profitable. That is also the solution to the general question.

As a player at the table, the small stack in UTG is particularly weak, one can give out with the worst hands this range on a call. It is likely that there will be better conditions for the big blind and has the Shorty in the next two hands through the blinds and will lose a good portion of his stack or resign under circumstances themselves.
