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%.

As he bagged his winnings, he realized poker wasn't a game of cards played with people. It was a game of people who didn't realize they were just variables in a very long equation. Mathematics of Poker
In his mind, a decision tree sprouted. He had an overcard and a royal flush draw. He calculated his —the mathematical share of the pot he owned based on the probability of his hand winning by the river. With 12 "outs" (9 spades for the flush, 3 non-spade Queens for the straight), he had roughly a 26% chance of hitting the best hand on the final card.

He sat in Seat 4, his eyes fixed not on his opponents’ faces, but on the geometry of the pot.
"Your move, Professor," growled Miller, a regular who played by "feel" and lost by the same metric. Elias glanced at the board: . He held A♠ K♠ . "You should know you're an underdog
"The math doesn't quite get there," Elias whispered. His equity (26%) was lower than the price he was being offered (28.5%). In a single instance, it was a "fold."
