Stars 180 - Low Straight on Turn

[BlackAndRed]

Hi all,

I would appreciate any help with how I played this hand.

About 40 left in this Stars 180 $22. Villain has been slightly tight-passive preflop and average postflop.

On the turn, I raise 800, figuring I'll represent a mediocre hand, while at the same time narrowing the field.

I then decided to push all in, because I concluded that the possibility of an evil river card (flush, likely straight) outweighed the risks of a better straight. I also considered check-calling a medium bet on the river.

Thanks!
