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?

Given a check, what would your next step be?

Btw, I probably bet this flop 50% of the time, but will usually do it against tight/straight forward types. I didn't think the halfstacker was likely to fall into this category, so checked to see what developed.

fold, getting it in with AK high for 40bb on the flop is spew.
