BQ: Making the 5 point is obvious?

JSD > 4 only for the 4th play.

Have a couple of questions.

1. Please explain more fully the concept of putting pressure on the 17 point checker by moving up to the 23 point. I see now there is a direct 6, but notice that piece now has more pressure on *it*. I would expect an exchange of hits would not hurt White too much, so do not understand why putting pressure on the 17 is important.

2. Slotting the 9 point, with a view towards either extending the prmime or rolling it forward looked like good bet. I figured that if I made the 5 prime on the next roll, the position would be very solid, especially given the close race. So, don't see why this is the inferior play to the "pressure" play.

The score (after 0 games) is: phunktor 0, You 0 (match to 3 points)

Move number 3:to play 11
