Red is in a good shape, having trapped a white's checker behind a 4-pt prime and having 2 anchors in white's board. But does that justify a double now? Yes, because white's chance for escaping is limitted and on the other hand there's a decent chance that white may leave some other shots soon. Thus red might well lose his market by delaying.

PS: I did a mini-rollout and to my astonishment, not doubling become a more serious mistake .06
