Liz Lieu is indeed a Poker Diva

KLuber:310,000
Lieu:144,000

Ron Kluber completed from the small blind and Liz Lieu checked her option. Blinds are 4,000/8,000 with 12 people left on the tourney, already in the money.

On a flop of (6d Th Jd) Kluber led out for 20,000 and Lieu made the call. The turn landed the (5c) and Kluber pushed a stack worth 95,000 into the middle forcing Lieu into the tank.
After several minutes she layed down (4d 7d) with Kluber following suit showing (Jh 8h) and the pot.

So she folded an open ended flush draw, I like to get an idea as to when is the correct time to call with open ended flush draw with one card left(river) in an MTT, maybe my imaginary friends can help me out here.
