It's way easier than trying to count each point that has checkers on it. Also, his system gives you both numbers which is important for close doubling decisions, (i.e. being up 9 pips is quite different if you have 90 pips to go instead of 110). One thing I do is 'keep' the first total counted on my fingers so I don't forget it when I'm counting the 2nd side. Left hand is 10s digit, right hand is 1s digit. Extend left to right one finger for one through five and 'retract' (leave all fingers out but tuck one in) for six through zero. ```
