$22: Plug this leak?

[Costanza]

This game put my downswing at 30 buy-ins -- I can start complaining now, can't I?

I've been looking back through some hand histories to look for stupid plays I made. I think this was one of them.

I rarely -- meaning this is the only time recently I can think of that I didn't push when I had less than 8-10 BB -- do this, but it seems to have been working well against me lately so I thought I'd give it a try. How bad is this play?
