Duh!

Then 44-88/Ah5h/Ah3h/Ax7x looks waaaaay more likely than anything else. The turn bet is too weak to be a made hand unless he has 5h8h/5h3h and these aren't that likely given preflop.

There's a chance you're drawing dead, but I think it's more likely that he's still drawing and you're ahead, so I like a push.
