I tend to get these wrong a lot - often there's a bot move that I overlook, something like  24/16 8/4 6/2 that makes no sense to the human brain but appeals to the bot.

But my pedestrian sensibilities say make the 4 point, and then it's a choice between making the deuce, running with 24/16, or making the 18.

I don't think we want the deuce yet, 24/16 seems to just ask to be hit, and I really don't particularly care to hold the three point, so I'll make the bar.

22/18(2) 8/4(2)

The main idea here is to abandon the POS 3 point and make the much more desirable bar point anchor.  All the top four plays involve making the bar.  Once the bar is made, making the 4 is the next step, although making the 9 is not at all far behind (ie close enough that I won't trust gnu 0-ply)
