My most useful program is Holdem Manager 3. I use the HUD part when playing and i also like that it keeps database of all my hands that i play. I like to mark some hands in which i am not sure if i did the correct thing while playing and later to review them. Sometimes i also use the free equilab software to check equity of certain hands and/or ranges.
My “lab” or should say study lab consists of a bookshelf with dividers breaking down the elements of poker into - math - psychology - strategy - bankroll - and various other elements..does anyone have a lab like this or do you only go off the head when it comes to playing the game with no reference to each element to build?
