Tourney hand odds
 

Flop is K-Q-10 of different suits. I have AJ offsuit for the nut straight. Opponent has KJ offsuit. We both get all-in on the flop (no-limit).

Turn comes J. River comes K, giving my opponent a backdoor runner runner fullhouse. What were the odds against my opponent backing into the fullhouse? Thanks.

With 2 cards to come, there are 990 possible outcomes.

837 times you win with the straight
129 times he hits a straight too for the split pot
23 times he hits a full house
1 time he hits quads

So, he has 23/990 = 2.32% of winning with the full house, 0.1% chance of hitting quads.

Overall you are 84.55% to win, he is 2.42%, split is 13.03%
