Introduction
In live poker, the line between winning and losing a crucial hand isn't always about the cards or the math — sometimes it comes down to an involuntary gesture, a pause that lasts a beat too long, or the way you handle your chips. Tells are the physical and behavioral signals we give off without realizing it, and any observant opponent can exploit them. Episode 997 of the PokerNews Podcast tackled exactly this topic, featuring Nacho Cuesta, author of "Master Poker Tells," alongside hosts Chad, Mike, and Ben. The conversation centered on the nature of tells in live play and broke down concrete examples drawn from recent tournaments. In this article, we explain what the most common tells are, why they matter so much in today's competitive environment, and what you can do to lock down your table presence.
Development
Tells have been part of poker since the very beginning, yet their systematic study remains unfinished business for many players. Nacho Cuesta, whose book "Master Poker Tells" focuses on this field, draws a distinction between conscious and unconscious tells. The former are gestures a player executes deliberately to deceive an opponent — the so-called reverse tell — while the latter arise automatically as a response to stress or emotion, and those are the truly dangerous ones, because the player producing them never notices.
Among the most common tells discussed on the podcast, standouts included facial microexpressions in response to strong or weak cards, changes in breathing rhythm, the speed at which chips are bet, and where a player's eyes go after seeing the board cards. Any one of these indicators can hand a valuable piece of information to an attentive opponent.
From a more technical perspective, tell management connects directly to the concept of balance at the heart of the GTO (Game Theory Optimal) approach. A balanced playing style doesn't just mean mixing value bets and bluffs in the right proportions — it also means maintaining consistent physical behavior regardless of hand strength. If your body language shifts when you have the nuts versus when you're bluffing, you're giving away information that no mathematical equation can compensate for.
High-stakes live tournaments — such as those at the World Series of Poker or the European Poker Tour — are the arena where tells carry the most weight. With million-dollar pots on the line, elite players invest significant time and resources in studying their opponents' behavior. Cuesta and the podcast hosts used clips from real hands to illustrate how certain gestures preceded the costly mistakes of the players who made them.
To minimize your own tells, experts recommend developing a standardized routine for every action: always the same amount of time to think, the same posture when betting, the same visual focal point. This discipline not only makes it harder for opponents to read you, it also sharpens your focus and reduces emotionally driven decision-making. Practicing in front of a mirror or recording your sessions at casinos where it's permitted are useful tools for identifying behavioral patterns you might not even know you have.
Why It Matters in the Ecosystem
Interest in tells is experiencing a resurgence within the global poker ecosystem. While the online side of the game has driven years of solver analysis and pure math, the massive return to live tournaments following the period of health restrictions has brought the human element of poker back to center stage. Events with record-breaking attendance figures — such as recent editions of the WSOP — have made it clear that reading opponents is still a very real competitive edge. In this context, figures like Nacho Cuesta fill a valuable space by systematizing knowledge that was previously passed along orally or intuitively, bringing applied psychology in poker to a wider audience.
Additional Context
The PokerNews Podcast is one of the go-to shows in the English-speaking poker world, with nearly a thousand episodes under its belt and a loyal audience of recreational and semi-professional players. The fact that they dedicated a full episode to tells alongside a specialist author reflects the growing demand for content that goes beyond purely mathematical strategy. For Spanish-speaking players, the existence of resources on this topic in Spanish — such as Cuesta's own work — is especially relevant, since historically the vast majority of technical poker literature has been available only in English, which has represented a barrier to entry for many Spanish-speaking fans of the game.
