THE COMMENTATOR IS A DOOFUS?!?! You have the STONE COLD nuts, and you check?! Who cares if she folds if you bet?! You have absolutely no chance of losing the pot, put more money in! As she says after the hand is over, she believed they were splitting with just quads! She may very have called! Checking the stone cold nuts in position on the river is, without a doubt, the stupidest play any hold'em player can make.
