Have you ever experienced that?.. I have.. 90 players 3 dollars buy-in knockout sit&Go and final table. I was in good position with big stack but wanted to knockout a player with my flush,ace high..
My cards: AdKd
opponent: 2d4d
flop: 3d 10d 5d
Both all-in...
turn: Ks
River: 6d
You can imagine my expression when I understood what had happened

"nh", I stood up to get one icecold beer "cheers" and registered to next tournament

Well at least I know I played my cards right. This is something you can call BAD BEAT.
