| White to play 2-1. |
Now it is correct to move both men from your bar point to your 6 and 5 points. You gain nothing by preventing Black from playing 6s, for he has no 6s to play other than those from your 1 point. The only numbers that can cause Black to destroy his board further are double 4s and 3s, and this will still happen even if you clear your bar point.
By entering your men, as you have, it is unlikely that you will be forced to leave a blot for several rolls, if at all.
To summarize: When it is possible to maintain comfortably a position that will cause your opponent to destroy or further weaken his threat, then you should do so. You should not when the gain is small and your risks are increased, as in the case of 14a. (By maintaining your bar point you are not causing any further deterioration of Black’s position, but merely extending the possibility of being forced to expose a blot — slight though it may be — as you attempt to enter these two men.)
