9s also make a good sidecount playing 9 v. 7, i.e. double when 9s are rich.

Some systems sidecount 10s simply because they are so important in so many plays.
Very interesting first post bigedge.
Also 12 v2 in monster counts, adjusting insurance decisions when playing halves, etc.
Look forward to further posts.
