Ok, I'll give it a try without taking a look at any gnubg analysis. * Øystein Johansen <[EMAIL PROTECTED]> [070619 20:36]: > Hi all. > > I'm browsing through some positions in the benchmark database, and some > of the positions are really wired.

A few general considerations to the position: - o has three nearly dead checkers on his 2- and 1-point. - besides his 8-point o has a ultimate stripped position and will most likely leave shots within the next 3 or 4 rolls - getting hit is obviously not decisive - x has too many spare checkers on point 20/21 and will loose flexibility if only te checkers on the 15-point can move freely. - x first goal should be getting more control of both outfields before he hits a potential blot of o. - x should not consider covering the blot on his 5-point in the near future My first choice would be something like 20/14(3), 21/15 to switch some spares into o's outfield. In general I'd strive for a classical prime vs prime position (as x), because of the three dead checker of o. > +13-14-15-16-17-18------19-20-21-22-23-24-+ > | X | | O X | > | | | | > | | | | > | | | | > | | | | > v| |BAR| | > | | | 6 | > | | | X X O O | > | | | X X O O | > | O O | | X X X O O O | > | X O O | | X X X O O O | > +12-11-10--9--8--7-------6--5--4--3--2--1-+ > Joseph-ID: AEAADGLMDHPILNIBCABA > X to play 51. x should not hit the checker on the 22-point. That checker is badly placed at least for now. I'd either make the 12-point (17/12, 5/4) and wait for the remaining checker coming nearer to home or move 12/6.
