Zeebo Theorem

Posted on Apr 06, 2009 by Gugel in Hand Reading and Tells, Poker Theorems

This week is Theorem Week!   Ill be talking about Zeebo Theorem, Baluga Theorem, Clarkmeister Theorem, The Yeti Theorem, Aejones Theorem, and Ansky Theorem.

So lets kick things off with Zeebos Theorem. Simply put, Zeebos Theorem states that no one ever folds a full house. It doesnt matter if you make a 1/2 pot sized bet, a full pot sized bet, or massively overbet. The villain will not fold their full house, even on a very dangerous board.

Lets look at an example

Hero (Button) ($100.00)
SB ($100.00)

Preflop: Hero is Button with J♠, J♣
Hero bets $3, SB calls $2

Flop: ($6) 3♣, 5, 3 (2 players)
SB checks, Hero bets $5, SB calls $5

Turn: ($16) T♠ (2 players)
SB checks, Hero bets $12, SB calls

River: ($40) 3♠ (2 players)
SB checks, Hero bets $80 (All-in), SB calls

Hero wins $200 with J♠, J♣
Villain mucks 5, 6♣

So what are the implications of Zeebos Theorem?
1. If you think the other person holds a full house and you cant beat it, do not bluff. It is extremely unlikely you are going to get your opponent off their hand.
2. Massively overbet if you have a strong full house and you suspect your opponent has a weaker full house. They will call.

Every strategy has a counter-strategy.  And every counter-strategy has a counter-counter-strategy.  If you know that your opponent knows Zeebos Theorem, you should adjust your strategy accordingly. That translates to folding your weak full houses on dangerous boards to massive overbets. That can also mean bluffing someone off a weak full house with a massive overbet (though this is not recommended).

Finally, unlike some of the theorems well discuss later, Zeebos Theorem is remarkably reliable. You can be reasonably sure it will work against a wide variety of opponents.

Stay tuned for the next post in Theorem Week.  Baluga Theorem is up next.
