The alphabet of poker
You cannot make a single correct decision until you know what beats what — cold, without pausing to count on your fingers. Every fold, call and raise begins with one question: do I have the best hand, or the best draw to it? A player who hesitates on 'does a flush beat a straight?' is guessing at everything downstream — put the order to work in our which hand wins trainer until reading a showdown is reflex. Drill this ladder and the entire game slows down to a pace you can actually think at.
