Worst steal ever, quite possibly. You're second to act, so at any level buy-in, this is risky.

More importantly, you're at a micro level buy-in. They don't pay attention to an UTG+1 raise, they just see a raise and will call with K9+.

I'm generalizing here, but stealing from UTG+1 with a less than marginal hand in a micro buy in MTT is suicide.
