Definition
Plain language
The most popular form of poker, where each player gets two private cards and shares five community cards.
As stated in the literature
A community-card poker variant; heads-up no-limit Texas Hold'em is the canonical imperfect-information benchmark for game-AI systems like Libratus, Slumbot, and PokerSkill.
Also called: Texas Holdem, Hold'em
Why it matters: It matters as the standard proving ground for AI that must make good decisions with hidden information and bluffing opponents.
For example, in a hand of Texas Hold'em a player holding two hidden cards combines them with five shared cards on the table to make the best five-card hand.
