I once committed a worse beat on someone. One guy went all in preflop, guy in small blind called, and me in big blind also called. I had K8.
Flop came KJ6, guy on small blind went all in, I called. Guy who was all in preflop had AQ, guy in sb had KJ. I caught runner runner 8 8 to take them both out. The helmuth beat has nothing on that
(note. I would never have called but for the fact that I had so many chips. I put the guy on KQ or AK, and was simply looking to take him out)
