you were in great shape bc your 9s took away many of what he thought were outs if he was behind. You had 2 of his 4 outs (9s) to make the straight. Three of his two pair possibilities (6's) were negated bc thatd give you the straight
Its something in the 70%/30% neighborhood for you in this case. Maybe even 75%/25%
Thinking from his perspective, its tough to put you on directly 99. Say you had JJ instead, this is more of a coinflip now. He know has 2 outs for trips (7s) 3 outs for two pair 6s) and 8 outs for a straight (9s 4s)
I think you'd still be a slight favorite if this were the case, but Im sure itd be close to 50/50
Regardless tough beat
