A Quick Challenge on Preflop Equity; No Cheating!

[James.]

"bob" limps in ep with 7 [img]/images/graemlins/diamond.gif[/img]7 [img]/images/graemlins/heart.gif[/img], "al" raises with A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/spade.gif[/img] in MP, we're on the button with J [img]/images/graemlins/heart.gif[/img]T [img]/images/graemlins/heart.gif[/img] and we know the BB "ace" will call any number of bets with any two cards.

what is our best play? what is everyone's preflop equity in the hand? you have to make a guess without using any simulating software. write it down, etc. and next, check your answer:

bob with his 77: w%
al with his AKs: x%
ace with his junk:y%
us with JTs: z%

how'd you do? linky link to the answer

Here is my random Guess:

Bob: 27%
Al: 27%
Ace: 19%
Us: 27%

[88please]

Bob:25%
Al: 29%
Ace:19%
Us: 27%

Awesome. I should do some of this stuff more. Here is my guess:

bob with his 77: 29%
al with his AKs: 31%
ace with his junk: 15%
us with JTs: 25%

What's our best play? What, if we can see their cards? If we don't know what their cards are I'm mucking. If we can see them I guess the play is to reraise trying to get it 3-handed postflop trying to create dead money from SB and from the EP limper. But would the limper fold 77 for two more bets when back to him? I guess not. I guess if we know the SB will fold, our decision depends on knowing our equity against the 3 other hands. If we have more than 25%, we should raise. But it would probably be more complicated taking future postflop action into acount - especially if we can see their hands there too.

how do you calculate this.

[Scarmiglio]

bob with his 77: 26%
al with his AKs: 30%
ace with his junk:18%
us with JTs: 26%

I would just call preflop. I don't mind having more players in the pot when I'm holding JTs.

agreed. from a strict equity standpoint, calling is likely the most profitable play.

there might be some circumstances that would add value to jamming preflop(increased fold equity, possible free card on the flop, etc.), but when you are at a minimum 4-handed the risk of this usually doesn't outweigh the benefits of cold-calling(preserve implied odds, encourage SB and BB to enter, etc.).

fwiw, my guess was as follows:

JTs: 26%
77: 25%
AKs: 35%
random/BB: 14%

it's good to think of situations like this and try to estimate your equity. it allows you to better assess in action at the table and plan the best course of action with your holding.

as far as i know, there's not really any simple "calculation" to figure these equities. it's more of an educated guess that comes with stoving/evaluating these types of situations away from the table.
