Grant Hoffman recommends: 6/2

We need to just make either of the slotting plays 6/2 or 6/3 4/3.

I would probably make 6/2 then if we roll 62, at least we make the 2 point but this is not a big deal either way.

Neil Kazaross plays 8/3 6/4.

I simply cover my 4 point and slot the next point in line. I could run a checker to the midpoint in relative safety, but I think that would be a blunder when down a few pips.

  1. Chuck Bower says:

    Is our primary gameplan (there I go plugging Mary and Marty’s book again) blocking or racing? The answer tells you which point to make.

    • Mary Hickey says:

      In the book, though, we tell you the answer >>

      The bar point is best in case we get far enough ahead in the race to double. It makes a big difference what pip deficit will let him take. So yeah, go with our current lead by making the bar, and hope our lead continues to grow.

      Good to see you here, Chuck!

  2. gary oleson says:

    make the bar and stop to consider the cube

  3. Joshua Riddell says:

    I just bring four men down.

  4. Vinson Blanton says:

    13/10(4)

  5. Philippe Salnave says:

    Playing 13/10 blocks 5s but it is also hard to clear and 6/3 strips our 6 point. I think the bar is best since we are ahead in the race.

  6. Eric Stippler says:

    13/10(3) 6/3 The reason I like the (3) off the mid-point is that it does NOT strip it to 2 checkers. The solid 8-7-6 block is nice, but I want more flexibility to possibly build a broken five-prime in our outer board. The 4th move to build inside on the 3 equalizes our offense with black.

  7. Philippe Salnave says:

    Make the bar point

  8. Barry Murphy says:

    13/10(3) 6/3 – clear the midpoint to 2 to get off safely, make asset 10 point and make inner board 3 point.
