Yes. Easy jam. Because you know he's going to call the last 280, you're pretty much putting in 680 to win a pot of 1680. That's almost 2.5:1. KTs has to be ahead of whatever his minraising range is, and you really need a double up to have a chance at 1st or 2nd.

Sorry he had AK this time or sucked out or whatever. Take solace in that fact that if you fold there, you're probably going to bubble out or at best get 3rd anyway (barring a nice run of cards). KTs here is by far your best shot here, so take it.
