Ha Ha Ha!!! It even says 'pass' at 0-ply!

My 2-ply evaluation says:

Evaluator:      CRASHED

        Win     W(g)    W(bg)   L(g)    L(bg)   Equity  (cubeful)
static: 0.991   0.000   0.000   0.009   0.009   (+0.948  (+1.000))
 1 ply: 0.091   0.000   0.000   0.769   0.093   (-2.280  (-2.242))
 2 ply: 0.119   0.000   0.000   0.798   0.136   (-2.377  (-2.309))

No double           : -2.309
Double, pass        : +1.000   (+3.309)
Double, take        : -3.854   (-1.545)

Correct cube action: No double, take

Are you sure you use 2-ply for cube decisions?

At least this shows that the CRASHED network is a bit of in this
position. Will there be any upgrades of the nets Joseph, or have you
reached a point where it's too hard to improve?

Not in Windows either. Should the copy option of the pulldown menu
be connected to the 'copy' command?

(Actually there should be 'copy ascii', 'copy html' and 'copy latex' etc)

The reason I didn't connect the menu to the command, was that I was under
the impression that Gary had some kind of other plan with that menu option.

Right Gary?
