Explanation of Effective Stacks

Thanks to the rule of 'table stakes,' players cannot be compelled to bet more than what they have on the table. The highest amount a player can wager during a hand is therefore known as the effective stacks .

Let's consider a scenario involving two players engaged in a heads-up poker match.

Player A: Stack 150bb
Player B: Stack 85bb

Even though Player A has a total of 150 big blinds in his stack , Player B is limited to betting only 85 big blinds, as that’s all he has available. The extra 65 big blinds in Player A's stack won’t influence the betting because he is unable to risk them. Thus, we can say that the stack sizes stand at an '85 big blinds effective ' level.

The situation complicates when additional players are part of a hand. Picture this scenario.

Player A: Stack 150bb
Player B: Stack 85bb
Player C: Stack 50bb

It's apparent that we have multiple effective stacks in play during the hand. Player A can only bet 50 big blinds against Player C, but can wager as much as 85 big blinds against Player B. When all three players are all-in, a side pot forms. The three participants will compete for a main pot totaling 150 big blinds (50 big blinds x 3), while Player A and B will contend for a side pot of 70 big blinds (35 big blinds x 2). Example of Effective Stacks in a Sentence -> Most online cash games generally operate with an effective stack of 100 big blinds, although you will sometimes encounter players who prefer shorter stacks.

Incorporating Effective Stacks into Your Poker Strategy

Across all forms of poker, the effective stacks significantly impact strategies for play after the flop. Here are some fundamental principles to consider.

Shallow effective stacks . When referring to stacks considerably under 100 big blinds, these shallow stacks mean a broader range of hands can be played effectively after the flop.

Deep effective stacks . When we talk about stacks that are noticeably over 100 big blinds, players need to hold stronger hands to justify committing their stacks after the flop while playing with deeper effective stacks.

The standard buy-in for most cash games is regarded as 100 big blinds, though some variations, particularly live games, permit players to buy in for deeper amounts (200 big blinds or more). Mastering play with shallow effective stacks is crucial for tournament players, as they often begin with 100 big blinds, but the number of chips they hold tends to decrease rapidly with escalating blind levels.
