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?
Don't do it. I wouldn't recommend it to anyone. I am just doing it because I don't like playing these freerolls at the beginning and don't have time to grind trough first 2 hours of bad game play. I am giving it about 1% chance of working out.
For our Championship series newbies are perfectly OK. Especially, if SwC is cheeking for alt accounts and it seems you guys had some info regarding that.
