60-Minute Master: Spin & Go Part 3: How to Determine Effective Stack Size

Due to the format of Spin & Go tournaments, our stack size will determine the playability of our hand. As our effective stack size decreases, we should be raising, calling and going all-in with more hands. However, if our effective stack increases, it will allow us to play tighter.

So what’s the best way to know the effective stack at any given time? Well, the effective stack is determined by the player with the smallest stack currently in play in a heads-up situation. If we’re in a 3-handed pot, the effective stack is the second largest chip stack. Very simple.

EXAMPLE SITUATION

Now, let’s take a look at an example. If we have 5,000 chips in the Big Blind and the Small Blind has 2,000, then the extra 3,000 in chips does nothing for us because we are only playing for the 2,000 chips that the Small Blind has in front of him. However, if the Button has 500 chips and goes all-in and the Small Blind has 2,000 chips and calls, the effective stack is still 2,000 since we have the Small Blind covered. On the other hand, if the Button goes all-in and the Small Blind folds, the effective stack is now 500.
