    The candidates I would consider are 13/7(2), 8/2*(2), 13/10(2) 8/5(2),
    and 23/20 13/10 8/5(2). Making the 5pt seems better than making the
    bar point, since it gives us such a strong board as well as a solid
    four-prime. But I'm tempted to PoH. It puts O on the bar against a
    four-point board, and gains a tempo that O might otherwise use to do
    something useful (e.g., escape or make a point). We don't have much
    ammunition for a blitz, but this could turn into a blitz, and even if
    it doesn't, I think the gain of time is useful.

    The combination of what looked like an underpowered blitz and having three back checkers was enough to steer me away from the PoH play. I played 23/20 13/10 8/5(2), but that really cedes a lot. Your point about tempo is on the mark, Tim.
