I didn't pay much attention so is there any reason to fold against unknown?

I dont think u can fold in $20 tourney versus an unknown when the table is 8 handed. Im only folding against a tight player who i have a read on.

I play it the same.

OP, obviously a good play against that player, i would try and get a read on the player at that point in a tourny though, the EP raise might be scary, but again it depends on the player. I personally would reluctantly also push there.

Donki, did you have a read on the player? chat seems to point to it?
