I've just stumbled across this site ....
http://www.cs.cmu.edu/People/mummert/poker/
and it was very useful to me and my genral poker game. The basic idea is that this bunch of uni-studenst over in who-knows-where, invented a system which ran millions of poker hands at various tables , (tables ranging from extreamely tight to loose). The purpose oif this test was to determine the rankings of the pre-flop holdem hands. They came up with a few surpising points, many of which are quite contrary to accepted poker literature.
Of course it is important to note that these tests in now way determine your winnings($) only how often the poket cards won the round... But hey I'd like you to give it a read and tell me if it changed the way you play. Its a bit long winded but the intro is mainly dealing with their system which they used ot test it.. scroill down about halfway to see their card rankings and such.
