||blitz standard benchmark
In no-anchor situations I use the a blitz standard benchmark position:
With a 3-point board against a 1-point board, one checker on the bar,
one blot in the board, and two attackers on the blot, it is double/take.
More is double pass, less is no double.
From there on I made up a few rules like:
- 3 extra attackers is almost an extra board point.
- 4 extra checkers in the zone (in the second quadrant but not attacking
the blot) is almost an extra board point.
- A 4-anchor is 1.4 board points.
- A 5-anchor is 1.5 board points.
- Both back checkers escaped is 2 board pointss
- This way I can calculate a lot of positions over the board towards my
When there is no checker on the bar, but one in the board, and one blot
somewhere else, then a direct shot on this blot calculates as a bar blot,
but with one exception: these threat doubles are never double/pass.
