I Flopped the Nuts and Lost: Was the River Call a Mistake?

Your hand J♠ 10♠

Board 9♣ 8♦ 7♥ 2♠ 10♦

You flop the nut straight, bet the flop and the turn, and the 10♦ on the river makes queen-jack the new nuts. He bets 19 bb into 28.5.

  1. Call or fold the river? Decide before you read on.

    The answer

    Call. You need 28.6% and you win 78% against the hands that bet this river (straights, sets, two pair). The call is worth +32.9 bb, and this time it loses to queen-jack: a right decision with a bad result.
