was this way too wreckless early on? obviously i would have preferred to raise all-in but this guy did it. i've been cleaning up on these $10+1's lately. here was my rationale. if i lose i still have $300 or so and would still feel fairly confident to make a comeback. if i don't, i'm out early and can start up another one. i also figured with these players this guy probably did have Ax or a small-mid pp.

is this something a good player would think about calling at this level?
