    Clearly not. I don't even know if I hit at dmp which means here it would be suicidal.

    Hitting isn't the only tactic to contain a straggler; you can also try
    to rely on outfield coverage. The outfield coverage here after bar/17
    is pretty good. On the other hand, if you hit and are hit back, then
    O's strong board means you're going to be in big trouble.

    In the variant, I have weakened O's board to the point where XG hits,
    despite the increased risk of losing a gammon.
