sorry but what do you mean by "M"?

[/ QUOTE ]

'M' is calculated as your stack divided by the total of the blinds and antes for one full circuit of the table, ie the pot size before pre-flop betting. It was created by Paul "X-22" Magriel (sorry if I misspelled that) a professional backgammon and poker player who incidnetally knocked Phil Helmuth out of the main event this year.

In HOH2, Dan Harrrington talks about the range of plays open to you based on your M. Think about a close football or basketball game, as the time runs out the teams are more limited in their choice of plays, in football, you have the two minute drill and then the hail mary pass. In poker, when a player's M is greater than 20 a player has the ability to use his entire skill set, between 10-20, a player loses the ability to play many speculative hands, bewteen 5-10 you're down to premium hands, between 1-5 your choice is down to any pair, or any two 10 or higher and you should be pushing all-in everytime you get these hands so long as no one is in the pot before you. Under 1, you're in the dead zone and no matter what you do, you'll get called.
