Walter Montego: Do you really want me to say here? lol. The program graded your play as "Beginner". It is a very harsh judge, though, and all of the top players whose games I've analysed get "Awful!"s and "Beginner"s as well as the "Expert"s and "World Class"s. ("Top players" doesn't mean world-circuit top players, but those at the sites at which I play).

I've made my GnuBg stricter on evaluating individual moves than the standard version (so, for instance a fairly good move on the standard is a Doubtful move on mine, a Doubtful on standard is a Bad move on mine). On that basis you got 6 Doubtfuls, 2 Bads and 1 Very Bad. (Standard settings: 2 D, 2 B and 1 VB)

The two Very Bads were failures to hit blots. The two Bads were both doubles (a 4-4 and a 5-5). It's a surprisingly common error. Many of the games that I've analysed show good play apart from a failure to take the best advantage of doubles.

The bad luck that Walter is referring to is me being hit and sent to the Bar 11 times. And with that last hit I was on the Bar for 13 straight rolls despite the 4-point being open the whole time. Odds of 10,000 to 1 or something. Walter was very hospitable though, and I got very drunk for free in his bar. ;-)
Walter vs playBunny

All that being hit forced my own play somewhat and I made 1 Doubtful move and 1 Bad one. Overall I was judged as "Advanced" (which is the category below "Expert").

Revenge is not happening yet, either, as that dice guy is still working overtime creating doubles for Walter, lolol. He won our last Best of Three and is looking to take this next set, too. [I say that hoping to provoke Fate into doing something before it's too late. ;-)]
