Thorson in Casino War

So suggested Jeff Sarwer as a bizarre board came out for heads up players William Thorson and Giacomo Maisto to ponder - {7-Clubs} {2-Spades} {7-Diamonds} the flop, on which Maisto bet out 1,500 and Thorson called, {7-Spades} on the turn which saw no action (but a query from Thorson: "What do you have, seven-three?"). This was clearly not the case, as the river brought the fourth {7-Hearts} .

Now out bet Maisto, 5k out of his remaining 15k or so. Now Thorson talked to himself for a while.

"I don't have an Ace, I'll tell you right now," he began, before starting to talk himself into doing something or other. "One part of me believes you..." he continued.

Now Maisto piped up, "You have a lot of chips, call!" and this seemed to have the opposite effect. "You should have said fold," he reasoned, "Then I call you." But he folded and then pestered Maisto to show him one card - "The worse one."

Maisto obliged with the {5-Spades} and Thorson said, "I could beat that," before letting that smallish pot drift away.
