omaha beat... not a bad beat tho' some thought it was

this one's pretty funny ! playing omaha tourney on pokerstars one day a while back & I'm SB with Qd Jd & 6 7 (don't remember the suits of the 6 & 7 ) nearly the entire table limps. I think only 1 guy folded. so I'm thinking "I might as well see the flop with this mess, I'm getting great pot odds"
well, I get an absolute MIRACLE flop !!! 9d 10d Kd
weeeee....... a flopped K hi straight flush !!!!!!!
well what can I do but check & call here ?? but here's where it gets fun !! BB bets pot UTG & 2 more players call !!! WHAT ???????
ok now for the turn ....another 9. same thing , bet call call call !!!!!! now I'm really wondering just what the heck is going on !!!!!
river .........K now I lead bet UTG raises & one guy reraises so I'm like "what the heck?" I put in the 3rd raise for all my chips ! ALL FOUR CALL !!!!
now for the showdown ! I don't believe what I'm seeing but the hands are as follows ( I'll just give you the 2 cards that played for each player. I don't really remember what their other cards were & after this hand my computer crashed & I don't have that hand history available)
UTG) Ad 8d flopped A hi flush !
player 2) Q J flopped K hi straight !
player 3) 9 9 quad 9s on the turn !
player 4) K K Ks full on the turn & quads on the river !!!

not sure how UTG & player 2 call, but whatever. 3 & 4 I think are stuck !
now for the sad part .......this happened in a FREEROLL !!!!
