this is a challenge idea that i think would be exciting, maybe it has been done before:

2 or more players deposit a set amount of money, and each tries to build up to a goal figure as fast as possible, racing the other players there. maybe this would be 10$ to 100$, or 100$ to 1K

just like a tournament, there is a prize structure, but the prize pool is made of all the growing bankrolls. as soon as someone hits the target figure (like 10$-100$), all the bankrolls are frozen and turned to a prize pool. if ten players enter then it would be something like

1st-50%
2nd-30%
3rd-20%

the challengers have to agree on stake parameters, otherwise the best strat would probably just be to fire big MTTs or cash games and disregard BRM

what would make this challenge so fun is the freedom each player has to play mixtures of different game types. the prize structure could also be winner take all

what do you think?

This format would be really interesting.. Instead of HU4rolz battles you could challenge someone to a bankroll freezout. It’s also allows for a more skill based competition
