61P-43U-43?

This one came up recently and I decided to do a 15K rollout. The funny formatting below is because I rolled out each move on a separate processor, with the same seed in each case.

My impression is that not too many people play 43U in response to 61P. I do because I'm rather fond of 43U in general, and also because there are many rolls that my opponent is likely to play incorrectly.

Unlimited game: tchow to play 43
