A worked example

Say each player puts $100 in before the flop, making a $200 pot. On average KTo takes back $119.12 of it, which is $19.12 more than it put in, and QJo takes back $80.88, $19.12 less than it put in.

Think in thousands: about 592 of 1,000 go to KTo, about 401 go to QJo, and about 7 are chopped.
