Its important to stereotype your opponents in
poker. Are they rich; Do they need the money? Are they
on vacation; Do they have a limited time to win? Are
they a professional; capable of being bluffed? Are
they an amateur; unwilling to lay down small pairs?
Are they winning? Are they losing? Are they a smart
ass; willing to bluff you at every opportunity? Are
they a women; less likely to bluff, more likely to
call?
     Being politically correct in poker doesn't work.
Although being prejudice will cost you heavily, as
every demographic plays every possible style.
