I agree with you and prefer MWC to an equity number when looking at point matches. Equity becomes important when you're looking at cash games, I feel. Anyone care to differ?

The way I read the documentation at http://www.gnubg.org/win32/gnubg/gnubg.html#Equities, when gnubg evaluates equity, it is talking money equity, not match equity.  Thus MWC is different from equity for gnu.

At least this is what I infer from the way the doc-gnu-mentation distinguishes between the two.

ty. But what about GWC? (Game winning chances) I mean that GWC must be the same as EMG as it calculates your chances of winning the current game. So taking into account both GWC and MWC is better, isn't it?

Basically what ever you use it doesn't affect what gnu thinks is the best move. So you can use what suits to you.

And let's make clear what is equity. (Game) Equity means expected number of won points in that game. Normally cube is not counted, so equity can be any number between -3 and 3. (from sure backgammon loss to sure backgammon win). For example is you get doubled and your equity would be less the -1 then you should pass and give the point (Now of course, you have to count the cube). This is different then game winning chances unless you some how count the gammons and backgammons also. Or you're playing to one point match when game equity truly is the same as game winning chances.

And to make it more unclear match winning chances are also sort of equity. It is same as expected number matches won. When playing particular one match it can only be from 0 to 1. For this reason match winning chances are sometimes called match equity.

Yes, they propably are refering to EMG, which is normalized money game equity, which is good indicator of errors also in match play. 

To put it simply:

Using EMG makes the size of errors compareable (which is not the case when using MWC)....a -0.1 blunder is a bad move not taking actual match score in account. At different scores this -0.1 blunder can lead to a loss of 3% MWC or 2% MWC or may be even less than 1% MWC cause here value of gammon's, single wins and all that match-score dependent stuff are taken into account. So with MWC you cant tell if your move was a generally bad one or bad depending on score.Finding your errors this may lead you on the wrong path.

The other way round a error of 2% MWC can be a blunder of -0.2 or -0.08 or at DMP may be only -0.04..you simply don't know it.

If you want to spot your conceptional misplays then EMG is better to remove your whoppers from your play. Nevertheless MWC also has its advantage and I sometimes have a look at it for difficult cubes.
