Dan Harrington's Zone System
Has anyone here read Dan Harrington's books and is familiar with the Zone system he describes? In particular, he mentions that once your chip stack gets to a point where M is between 10-20, that you should avoid playing small pairs and suited connectors.
Now is he referring to playing those types of hands from early/middle position or playing them at all? I found it wasn't quite clear in his book. For those that aren't familiar, Dan breaks down your chip stack relative to the SB/BB/Ante. For example, let's say you're sitting with 10,000 in chips and SB is 500, BB 1000, and Ante is 500. Total of SB/BB/Ante is 2,000 so your M = 10,000 / 2,000 = 5.
Under his system he breaks down various styles of play depending on where your M currently is as follows:
M > 20 = Comfort Zone - Normal style of play
M 10-20 = Yellow Zone - Avoid small pairs / sConn's, bet aggresively with high cards.
M 6-10 = Orange Zone - Restrict raises to when you're first into the pot unless holding a premium hand. Pocket pairs and suited connectors now regain their value if you are faced with an All-In scenario
M 1-5 = Red Zone - Only bet should be All-In preferrably with you first to act.
M < Pot = Dead Zone - First into the pot before the blinds, players may not call if you are in early position due to fear of someone coming over the top.
In particular, what I'm most interested in is with respect to the changes in playing suited connectors and small to mid pairs and why that reveral takes place and whether he's suggesting we don't play them at all or only play them in late position.
