yeeeeeech!

What's the least bad move here?

He'll likely point on our head again if we enter with the four, but I don't think I'm in the mood to give him any more blots to aim at and there's nothing to do with the four if we enter with the one.

Bar/21 24/23 is awful, but it may be the least awful.  I'm open to other suggestions...

Exactly what I think. Ugly, but I won't leave extra blots for him to hunt.

Coming in on the 4-pt would give him 10 shots that both hit and cover.  Then moving up to the 23-pt would give him a couple more.  Double 2s and 4s would be particular devastating, putting both our back men on the bar, against a 3 or maybe even 4 point board.  An ace point game is rarely ideal but, under the circumstances, I think a more pragmatic move would be bar/24, 13/9.

I think we officially are in trouble here, but, again, cuz of the score, we cant get hurt too badly.

At this point I prefer to play with an anchor in his board, so my play is Bar-24, 13-9 It's true he has another blot to fire at, but its a 6 thats duplicated by the blot on his bar point.

bar/24 13/9 for me too, otherwise we stand to be hammered in the zone where surfers dread; the waves keep coming; you recover only to be smashed again. yes we need his 4 point, but we might need another stone back there, to get it

Entering on the 21 and slotting the 5-point comes out on top.  Now that's a bot move if ever I saw one.  The Herd's move is a close second, with the other vote-getting play not far behind that.
