Stars $10+1 line check

[Ryan Donk]

Hi, I just started playing Stars $10~$1 SNGs and feel they are quite soft. I know to play really tight in early levels but try to find exactly where to draw the line between folding and continuing on a hand. All input welcome...

No reads, 3rd level of normal $10 Stars SNG
