M = the ratio of your stack to the blinds and antes.
blinds 1000/2000 antes 500, 9 player table = 75000. your stack 35,000 makes your M = to 35,000 divided by 7500 or 7500 into 35,000 which would = about 4.5 of M
M zones in tournies =
20+ M - GREEN - steady normal poker. take a few shots, mix it up and play good solid poker and maybe even just a ring game stylee (i dunno)
YELLOW - 10-20 M - small pairs and suited connectors to be binned from early positions.
Orange - 6-10 M - - the above and maybe stop calling for odds sake. what sort f odds should you be making auto calls for anyhow? if im getting 3/1 i must admit i call with anything but NOT IN THE ORANGE M
(this is all new to me tonight but essential to each and every one of us to understand)
RED 1-5 M - 'danger danger will robinson' action dan tells us. I forget but i think your just in any pot that n one had entereed and your all in with about any 2 big cards.
He describes a zone below RED zone even but really its not a place that you want to put yourself conciously so ill forget it.
Anyhow i will cntinue this later when i understand it all more. Look out for

...nothing.
