Worth a call?
 

Early tournament hand...I've managed to triple up by this point, but there's one other at the table with my size stack:

I was planning to call until the big stack called. After that, I didn't want to get in a situation where he could push me off my hand on the flop, because he was being very aggressive.

Does anyone else call here?
