If by some miracle I manage to get a big stack of chips then I will leave the table for an hour and come back to play in later stages.
Is that a legit tactic?
Is this why people are going to sit out in the other tournaments, I'm playing in to learn it?
On a side note few more days left to earn my entry fee back in low rake.

I saw a lot of players doing this, but you have to gain a lot in the early stages to keep your bank alive
It's much easier on tournaments without "ante", only with small and big blinds, and it's much easier on full tables, 7 to 9 players
