Set + gutshot on drawey board

[Poker monkey]

I'm being a shortstacking ratholing bastard here with the express intention of taking more money off Brad Booth (mainly because I don't much like his spivvy facial hair and Cool Million antics). Kind of odd that he'd lead and then check the turn 3-way if he had the straight.

What do you do on the turn with just a psb left - check and allow free cards or shove it in?
