    Sorry but my only candidate play is 6/2*(2) 5/1(2).
    Why is this play less tasty than those egregious Hershey
    bars they sell (or used to) in the US?

    There's no reason not to PoH, but then do you play 8/4(2), 5/1(2),
    or 10/6(2)? Making the 4pt clearly has the strongest upside, since
    leaving a gap on the 4pt is just asking for trouble later, but is
    it worth giving O four hitting rolls from the bar? Definitely,
    says XG. If we strengthen O's already formidable offensive position
    (see variant below) then XG says the decision is much closer, but
    it still favors 8/4(2).

    After 8/4*(2), the blitzing play is of course 7/3(2). This play does
    win more gammons and might be the gammon go play, but the downside is
    that it is committal---it sacrifices some of X's priming vig, while
    13/9(2) keeps both game plans open. Pursuing the blitz aggressively
    likely means leaving blots and shots in the next few turns, which is
    risky in light of O's strong board.

    The rest seems clear as we may want to/need to continue the attack and to do this diversifying our numbers (not duping sixes specifically) there is only one play.

    I liked peppering the outfield, but duplicating 6's is the problem.

    Re-making the eight point after the POH has it's merits, but with two
    runners to spring so does keeping the midpoint. I'll go for 16/6 since re-making the eight dupes sixes. Not sure.

    We want more builders in the zone. 13/8(2) is a candidate, but 16/6
    reduces O's return shots, and a builder on the 6pt is a bit more
    effective than a builder on the 8pt. Duplicated sixes play some role,
    but 16/6 would be XG's clear choice even without duplicates sixes
    (see Variant 2).
