Over recent years Zachary Elwood has become known for his valuable contributions regarding the subject of “tells” in poker — that is, actions both physical and verbal that can potentially provide information about a player’s hand in addition to what might be suggested by their checks, calls, bets, and raises.
Elwood has written two books on the subject, both of which have been especially well received by the poker community — Reading Poker Tells (2012) and Verbal Poker Tells (2014) — and he’s contributed a chapter to Jonathan Little’s new Excelling in No-Limit Hold’em due out next month.
