Here, I executed a match double accurately.
For money it would be a massive beaver.
Intuitively, I was confident in it based on the fact that
I have a few immediate wins and that losing the chance of
winning the match from 11A 1A is not much of a loss
compared to what I have to gain.
METs can be used to make the computation precise but
I was just using intuition.
I'm surprised that holding isn't more of an error than it is.
BTW, my cube action was perfect in this game -- I had no
earlier redouble. My PR sucked though because my
checker play was so atrocious.

You must have had an earlier redouble to 4. But I guess you mean
you did not miss any redoubles to 16.

Yes, I meant that I didn't miss any redouble to 16. Getting the cube action right,
owning the 8 cube, is extremely difficult normally but there's a huge amount of luck involved (luck in correct play that is, rather than luck in result). The luck is
in making the right guess when you're in coin toss mode and in being faced with simple positions.
