I personally use every thing I can , when I am playing LIVE poker as a Psychological weapon, even down to what I order from the Valet to drink, so:-
If I am tired I always order vodka and redbull.
If I am trying to
pretend I am just out for a social game and do not care if I win, I order Wiskey and soda.
If I am
pretending I am UP for IT ( I am serious) I always order Jasmine Tea Hot.
If I am going to win at all cost I drink water, with lemon.
I always buy as many players on
my table a large bear

in the hope they need the washroom quicker than normal ( I usually try and leave this untill the blinds start to bite)
WHAT DO YOU DO? and What do you drink while playing on the hallow Felt?
