Annie Duke was all in with [As][Ks] vs. her opponent's [Ac][Ah] on a flop of [Th][6c][3s]. Duke had a back-door flush draw and runner-runner outs for trips, but both failed to materialize when the turn came [3h] and the river a [6d], sending Duke to the rail and awarding her opponent a $5,000 bounty.
