Grant Hoffman recommends:

We should play 13/9 13/8 here, which makes our 8 point and goes for a priming game.

Although Neil has the better prime, we have only one checker behind his prime but he has three checkers behind our potential prime. Some players underestimate the value of having more of your opponent’s checkers behind your prime.

Neil Kazaross plays 23/15.

It is important for me to try to escape with a checker and also aim at my needed 9 point.

Comments

  1. Jeff Spencer says:

    Why not just pick and pass? 13/10*/4.

  2. Philippe Salnave says:

    Having a hard time finding the right play, I finally voted to make the 3 point. 24/21 13/7 is one of my candidates bearing on the 5 point.

  3. Karl Sours Karl Sours says:

    A 5 of 6 prime should do the trick. 9/3 6/3

  4. gary oleson says:

    make our 3 point. Neil’s position will be hard to improve upon and we should make another board point with this opportunity. we should have time enough to escape. we have spares to play from the mid point it will be difficult to hold our last checker with only 12 checkers available on his side of the board.

  5. Ben Elliott says:

    24/21 13/7.

  6. Ed Rozmiarek says:

    I was tempted to run out 24/15, but that’s just likely to get sent right back. I chose to send a checker back with 13/10*/4.

  7. Eric Stippler says:

    Considered bringing builder to the bar point and advancing to the edge of NK’s prime, but hitting on the 10 and bringing the same checker to the 4 is awfully strong.
