We had a great turnout for the chouette today – 12 players over the afternoon, although no more than 10 at any one time. Newcomers Oggie, Oliver, and Nate had not done a chouette before, and so we set up a beginner’s table for $1\/point, and the main table went for their usual $5-10\/point.<\/p>\n

It occurred to me that a sport’s bar is really a perfect spot for the chouette, because they had about 7 different events on various screens, and it was totally not out of place for a table to suddenly erupt in a cry of joy and\/or despair. We had a lot of those for the backgammon games too, and more than once I found myself saying “all I need is a double <insert number here> or better…”, either to win or to save the gammon. I think I got my roll each time, too!<\/p>\n

This position came up in one game where Oliver was the captain, and we spent a solid 2 minutes debating.<\/p>\n

\"gnubg-danbu_21p_2018-03-17\"<\/p>\n

The debate was: 7\/3(2) or 24\/20(2). Turns out, we went with the wrong answer. Extreme gammon says it’s 7\/3(2), and by going with 24\/20(2), we made a -0.004 error. Which is to say, you couldn’t really go wrong with either of those plays.\u00a0 +0.934 equity or +0.930 equity – I guess one is slightly higher.<\/p>\n

I have a couple of other positions from my table where there was a doubling decision, but running them through Extreme gammon shows the answer we arrived at was not only right, but kind of obvious.<\/p>\n

Mark F sent me a couple of positions from the other table that were interesting.\u00a0Brown was the box in our chouette yesterday, with white on roll. There were four 4-cubes on White\u2019s side of the board. What is the cube action here? Note that brown has 8 checkers left on the one-point.<\/span><\/p>\n

\"Untitled1\"<\/p>\n

In the actual chouette, all four team members doubled to 8. The box took all 4 eight cubes. The box lost, and questioned his take. But it was a very easy take, and in fact, it would be a huge blunder to drop. In fact, it was not a proper double, and white\u2019s error was .045 by doubling (a fairly small error).<\/span><\/p>\n

Note that white will be very disappointed they doubled after white rolls a non-double and brown rolls any double. Also, if white rolls a 1 or a 2 (other than double-2), black still has a take next roll.<\/span><\/p>\n

 <\/p>\n

Later in the afternoon, another bearoff cube action came up:<\/span>
\n\"Untitled12\"<\/p>\n

After learning about the previous position through XG mobile shortly after that game, brown was reluctant to redouble. And he didn\u2019t double. But actually, it is a clear double. And a double-blunder not to double! Here, brown can be off in 3 shakes without rolling a double, whereas white needs four rolls unless he rolls a double. That\u2019s a huge factor. White barely has a take. The cube equity after white taking is .961, so it would only be a small error for White to pass.<\/span><\/p>\n

Lots of excitement was expressed about next weekend’s Portlandia Backgammon Classic, and I’m super pumped for it. Hope to see you there!<\/p>\n
