200NL - AK on XXY flop vs halfstack

[redCashion]

I will usually push here vs aggro shortstacks, and fold vs passive/straight forward ones. I only have 10 hands on this villain so don't have a read, but his stats are coming up passive. But it occurred to me that some people might advocate getting it in here for half a stack against most opponents.

Thoughts?
