How should White play 22 here: It is good not to weaken your board, so you consider 13/7 13/11: This is the best of the moves that give up your midpoint, as it slots your 7 point. I have heard good players advocate giving up your midpoint in these situations, to avoid the awkwardness of you rolling 61 next roll. While that number would be awkward, if you kept your midpoint, then Black’s 61 and 11 force Black to break their 5 prime. Black rolling 62 would force Black to play 13/11 13/7, enabling you to hit with 61 next roll. It is worthwhile keeping your midpoint, so you consider 6/2 5/1: The idea is that you will be able to rebuild your board in the future, but you have reduced your board to a 4 point board with 2 blots. You can do better than this by playing 5/1(2): After this move you still have a 5 point board but with only 1 blot. It will be easier to make a 6 point board after this move, and you have retained your midpoint. This is the correct move. ...
