"Your move, Professor," growled Miller, a regular who played by "feel" and lost by the same metric. Elias glanced at the board: . He held Aâ™  Kâ™  .

Elias didn't think about whether Miller was "bluffing." He thought about . He had to call $400 to win a total pot of $1,400.$400 / $1,400 = 28.5%. Mathematics of Poker

Elias began stacking the chips, his expression unchanged. He knew the Royal Flush was just a statistical outlier, a flicker of noise in a long-term signal. He hadn't won because of the spade; he had won because he was willing to lose when the percentages told him it was the right move. "Your move, Professor," growled Miller, a regular who

But then he factored in . He looked at Miller’s betting patterns over the last four hours. Miller was "over-bluffing" on wet boards.
