X-ray in poker refers to the ability to determine with high accuracy the exact cards or a very narrow range of an opponent through analysis of their actions throughout the hand. Unlike the more intuitive soul-read, x-ray is based on deductive logic applied to each opponent decision. Players with x-ray ability systematically eliminate portions of the opponent’s range based on their bets, checks, and sizings. This level of reading is rare and requires vast experience and close attention to opponent behavioral patterns.
