Players' attention towards the game speaks volumes. Conversely, swift and controlled movements often accompany a strong hand. Subtle actions, like nervous chip shuffling or hesitation when handling cards, can indicate insecurity or a lack of confidence. Quick decisions might signal a strong hand or eagerness to bet, whereas prolonged delays could suggest uncertainty or strategic planning for a bluff. The time a player takes to act reflects decision-making. If a player likes a flop, for example, their eyes will quickly glance down at their chips, which is an indicator that they like their hand and want to build up the pot. Poker pro Daniel Negreanu is also a big proponent of eye contact being a useful tell.
