The structure of this tournament changes a lot in the bubble

The theory changes significantly , and it is extremely important to understand properly .

And in the final tablet changes much more.

Absolutely. The bubble often changes the entire dynamic of a tournament. Players who were splashing around suddenly tighten up because they want to cash, while bigger stacks can apply a lot more pressure and pick up chips uncontested.

I think understanding bubble play is one of the biggest edges in MTTs. Knowing when to tighten up, when to attack, and how stack sizes affect decisions can make a huge difference to your long-term results.
