Firstly let me thank everybody who has visited this website in the last year and especially those who have consistently left comments on the positions. They help me to understand how players thinks about the game.


The website is about to be transferred from one domain host to another. This is necessary to bring the site up up to date as support for Adobe's Flash technology ceases next year and the current site is reliant on Flash. The site will look a little different when it transfers and it will render properly on tablets and phones, something that it struggles with at the moment.


In theory the transfer can take up to a week to do but we will see. Because of the transfer and because of the Christmas holiday season I will not post again until Monday 30th December when hopefully everything will be in good working order. If, for any reason, you cannot reach the site just keep trying! In January the webiste will be seven years old!


I wish every reader a relaxing and enjoyable holiday season wherever in the world you are.

Match Play. Red leads 2-0 to 7. How should Red play 21?


The solution to this problem will be published on Monday 30th December.

Money Play. How should Red play 43?


Without education from the bots we would just shuffle the outfield blots with something like 21/14.


The bots gave us a fundamental lesson in how to play these positions.


Red wants to build a full prime from his 11-pt to his 6-pt to force White to crack his home board, rendering it useless. However, Red is ahead of himself and he risks White keeping his timing for any number of different back games. The only correct play is 6/2, 4/1!! Not a move you would ever find without understanding the modern theory of back games.


If you have never seen this type of play before please make note of the technique and reuse it.

XGID=aBB-BBB-----cC---cbd-b--B-:0:0:1:00:0:0:0:5:10


Match Play. 0-0 to 5. Should Red double? If doubled, should White take?


This is already nearly a pass for White because of the gammon threat and so the position is highly volatile. Virtually any roll by Red followed by a fan for White will make this a pass so Red must double now. Not doubling is a triple blunder.


Because of the gammon threat which, if executed, gets Red to the Crawford Game White only just squeeze a take from this position.


For money, the take is much clearer although it is still a massive double for Red.

Money Play. Should Red redouble? If redoubled, should White take?


Red got a huge bonus when White passed his redouble. In fact, it is the redouble that is in question, not the take.


If Red rolls a six he will lose his market but if he doesn’t and White then rolls an ace things will get interesting. A third of White’s wins are gammons. He has a trivial take.


Practically this is a great redouble because many will misjudge the threats but technically this is a redouble by the narrowest of margins.
