Stopping a leak.

[bobbycharles]

Is this a leak in my game? What is the standard play?

First rotation of MTT...no reads yet. All stacks approx. equal.

Hero in SB with A4s.
MP2 open raises with 3x BB.
MP3 cold calls.
Folded to me.

Hero??

I have the tendancy to call the raise early in a tourney and see the flop. Leaky?
