M and Head\'s up Play
 

I don't have HOH on me right now. Does it mention anything about using M for head's up tournaments? (not at the end of MTTs, but HU tournametns where you start deeper stacked).

I know how he uses Effective M, but with HU you are seeing a lot more hands that are playable, so it seems like it would apply differently. Sure, you can calculate your Effective M the same way, but the strategic implications seem different.

Obviously HU is more about your stack in relation to theirs, but I wonder how M might dictate your decisions as well.

Chapter Twelve of volume 2 deals exclusively with Heads Up play and discusses the problem of M.

Lee Jones claims to have a more thorough non-exploitable strategy for short stack heads-up than Harrington's (/Magriel's) M calculations: SAGE

It's easy to learn and I have applied it with some success.
