Hmmm... I can make another homeboard point. Or I can anchor and make the 10 point. Or I can anchor and hit on the bar point.
At anything other than DMP hitting seems clear. But being 22 pips up in the race and with gammons not counting perhaps a quieter play is called for...
I'll dismiss making the 3 since that leaves the blot on the 10 exposed. So, which is better: hitting or making the 10?
Let's see if some math helps: I figure 24/22 13/10 gets me to about 65% GWC. If I hit and anchor then I have a 50% chance of being hit (18 return shots). If I'm hit back, it looks close to even, maybe a slight edge to me because of my anchor. So, figure that hitting risks ~15% GWC.
OTOH, if I'm not hit, my GWC range from about 65% if the Herd anchors on the 4 to ~90% if the Herd dances. Figure about 80% on average. Which means that hitting risks 15% to gain 15%. Hmmm...well that little exercise didn't tell me much.
Aw, who am I fooling here? Everybody knows that I'm going to hit. (c:
And now that I've made my decision, I can back it up with some post-hoc reasoning: After the re-hit, the Herd has three blots to aim at while I have an anchor. Thus I'm probably more like 55% when hit, so the risk is less than what estimated above.
