Liftoff 1D: Kostelyna Gets there on Park

On a heads-up flop of 3♥K♥4♣, Jonathan Park checked, Stefan Kostelyna bet 15k, and Park check-jammed. 

This sent Kostelyna into the tank, but after a good while, he decided to make the call, putting himself at risk. 

Park tabled 4♠5♠ and was ahead of the 9♥8♥ of Kostelyna, but the runout of T♠2♥ gave Kostelyna the flush on the river to score the double-up. 

Kostelyna - 315k
Park - 225k
