With ten-high and an open-ended straight draw on a coordinated flop, checking allows a free runout to evaluate the river before committing additional chips.

The board provides two pair (Queens and Jacks with a King kicker), ensuring at least a tie unless the dealer holds an Ace, King, Queen, Jack, or 9-T. With dealer beating the board only ~44.5% of the time, calling gives an EV of around -13.4 chips compared to -20 chips for folding.
