Don't Want Or Need 7pt Here

My guess is 15/9 10/4. This play prepares to kill Black's 6s, thereby helping White to crash. This play also makes it easier for Black to bear in safely.

These are difficult plays, defending against a backgame. XG frequently tells me I have seriously screwed up in this kind of position. I may not be the only one who fails to understand some of the concepts involved here.

Although it is usually correct to make points in order in front of an opponent's anchor, I believe this position is an exception.

Black has no spares on his 22pt or 23pt, so making the 7pt does not really block anything except 44 and 55. The 7pt can be tough to clear in this position because you cannot play 4s and 5s from the 7pt.

Black would like to kill his 6s, but since he cannot do so on this roll, he can prepare to kill his 6s next turn by playing 15/9 10/4. This play increases the chance that White will eventually crash while Black will not have to play a 6 if he rolls 66 65 64 63. If White hits with 53 or 43, Black will have all kinds of returns.
