What this fixes

The bubble makes me freeze, and freezing is also a decision.

The risk premium, burned in. The bubble is where tournaments are won and where good players give money away by playing chip equity in a spot that pays in pounds. Busting costs you the cash you were about to lock up, so a call needs more than its pot odds. That gap is the risk premium, and this drill makes you feel it before you have to face it.

Questions

About Bubble Trainer

Does this mean I should never call on the bubble?

No. It means the bar is higher, and the drill shows exactly how much higher for the stacks in front of you.

Is this the same as the final table drill?

Same maths, different shape. The bubble is one jump with a huge field, a final table is many jumps with eight players.

Does it work for satellites?

Satellites are their own drill, because flat seat payouts push the effect much further.
