I'm sng - mtt microlimits regular player and the reason to play in tournament with "ridiculous" structures, are: I play hyper (including spin n go on pokerstars
), to "wam up". I strongly believe that as any other sport, i need to warm up before play for real. A few rounds of hyper before start sng and mtt turbo or regular, switch my mind in "agressive mode on", and allow me to size my day to day stamina, "tilt resiliance", among other variables to confront my poker session.
Other important reason to me, the hyper - turbo "ridicolous" structures, are the structure of almost any satellite to tournaments out of my bankroll, so, i play satellites of those tournaments when i have 100 or more buy ins of that kind of tournaments.
