4 Mistakes Every Beginner Makes with 15 Big Blinds or Less Short Stack Strategy

1. Too Tight When Shoving from Late Position

When your short stack is down to 10BB or less, you should actually be shoving far more often than you think. Again, ICM plays a role and you need to be mindful of bubble situations. But once you're in the money, your goal isn't to survive one more spot—it's to win the tournament. To do that, you have to be willing to risk your entire tournament life to apply pressure and accumulate chips.

Use solvers (like Holdem Resource Calculator or ICMIZER) to see how they handle ranges on the CO and BTN with 10BB or less. Is your shoving range that wide?

Example: In a default BTN shoving range at 10BB, hands like K8o, 86s, and Q4s are marginal shoves. Of course, you need to consider the players in the blinds and ICM effects. For example, on the bubble with 10BB, you shouldn't shove 54s, and you should avoid it if the blinds are calling stations. However, most opponents will be too passive against your aggressive shoves, allowing you to accumulate a ton of chips.

2. Too Loose When Shoving with 15BB+

This seems to contradict the first point, but just as players shove too tight with 10BB or less, they often shove too loose with 15BB+. While it's still reasonable to shove some hands at this stack depth, you have much more room to maneuver—you can add limps and raises instead of easily putting your entire tournament life at risk.

Think about it: if you limp or raise into a marginal or slightly -EV spot, that mistake is far smaller than shoving and risking your tournament life. When you have 15-20BB, the game is more about limping, raising, and maneuvering than simply shoving like you would with 5-10BB. Tournaments are the softest form of poker, so with a little study, your edge is large enough to give up marginal shoves above 15BB and instead focus on outplaying and exploiting opponents postflop.

3. Too Tight When Calling from the Blinds

While it's reasonable to tighten your calling range in the big blind against passive recreational players when short-stacked, regulars and stronger players will increase their aggression in this spot (and so should you).

Example: When facing a min-raise from the small blind with 20BB, you should defend with every hand. Spotting these situations will make you a lot of money—would you defend a min-raise with 32o when short-stacked?

Use programs like ICMIZER or HRC, or study a tournament masterclass, to dive deep into these spots. Just a week of practice will significantly improve your game.

4. Incorrect Shoving Ranges from the Blinds

(Note: the original text did not fully provide this section, but common errors also include shoving too wide or too tight from the blinds against min-raises, and neglecting pot odds. Based on context, this error typically refers to balancing your shoving range when defending against blind steals from the blinds—neither too tight nor too loose. Here is a supplement based on common strategy:)

When you are short-stacked in the blinds and facing a raise from the small blind, your shoving range should adjust based on the opponent's raise size and your stack depth. Generally, with around 10BB, you can shove a wider range, but you should exclude weak suited connectors that are too easily called. Use solvers to learn the correct ranges and avoid giving up too much equity against aggressive opponents.
