IMHO, 19/10 would be a miserable move.  Far better, surely, is 10/4, 7/4.  We could only be hit with a 61 and even then would be favourite to re-enter, with the added bonus of a possible return hit with a 2.  Let's put him behind a 5-prime, that's got to increase our chance of winning this game and so the match.

19/10 is the "obvious" play - we've got him trapped, now bring our runners around. The thing is, we still trail by 24 pips, so we want to retain contact and moving our last sentry around to join the army means we won't have any contact if he leaps.

Making the 5-prime seems a lot better.  Yes, it gives him a 1/18 shot to hit, but we still have lots of counterplay.  The only thing I don't like about it is that it makes 5-1 play well for him when 5-1 is a disaster if we don't make the 4 point.

That said, we will likely be bearing in against his anchor and having a gap on the four point is not pretty.  I say close it now.

10/4 7/4

Since this seems decided, and I wont be here tonight, I have decided to move it along.
