It doesn't exactly take a rocket surgeon to see that priming wins more
games while blitzing will win more gammons. The question is whether the
additional gammons are worth it.
XG says no by a wide margin. I opted to blitz here, as did some pretty
good players (e.g. NeilKaz), but the additional gammons are just not
worth it. Not sure how to judge these adequately, and since I mostly
play short matches where doubled gammons are worth considerably more
than for money I tend to err on the aggressive side.
I don't think the simplistic "just make the DMP play" is applicable to
enough positions to use it regularly, although it works here.
In the variant, I've moved O's checkers on her four to the six and
changed it to 5a5a match play. This makes blitzing a small error
according to XGR+++.
