With Blue's pipcount being 9(1) and White's being 8(2), Blue trails by 5 pips (one shy of a super-pip or supe). That should tell you all you need to know.

Nack, could you please demonstrate to us why this is all you need to know with a few more examples. Ie., what would the count iindicate to you at 7:3 and 4:1? 2 and 3? 2 and 3:3? 2 and 3:7? Can 3:7 actually happen or is it impossible to go Iover x:6?

At 7(3) and 4(1), the difference is 3(2) or 20 pips.
At 2 and 3, the difference is 6 pips.
At 2 and 3(3), the difference is 9 pips.
At 2 and 3(7), the difference is 13 pips.

You would apply these counts to the board position the same way you would apply them in traditional pipcount. It is one of the factors that might sway you to double or not, take or not, or to gravitate towards a bold or safe checker play.

The only examples listed above for which you might want to know the total are 2 vs 3(3), a 9 pip diff; and 2 vs 3(7), a 13 pip diff. The leader is at 2, which is 12 + 90 = 102 so those come to counts of 102 - 111 and 102 - 115.

Later on, I'll show you what to do if you want to save the conversion step to trad, but conversion isn't that hard, it's only for the leader's count, and the main point is that most of the time you have no need to convert -- only in a fairly tight range of differences and mainly for straight races.

There is no special problem with using "3(7)" in place of the usual "4(1)" (same count). In fact, for some people it's a cute little trick to change 4(1) to 3(7) on occasion. Say you end up with counts of 4(1) and 2(4) and it's not obvious to you that the difference is 9. If you convert 4(1) to 3(7), then it's easier to subtract 2(4) from it to get 1(3), which is 9. In case you have that stumbling block, though, it won't last long :)
