This should work.

Blue 66: 13/7(4)
White 11: 24/22 13/12*(2)

Blue 44: B/21 7/3*(3)
White 11: B/24 13/12(3)

Blue 66: 24/12(2)
White 66: 24/18*(2) 18/12(2)

Final pipcount: Blue 133 White 134

Bravo, Michael!

Here is a replay with diagrams:

	163
Blue will play 13/7(4)	167

White will play 24/22 13/12*(2)	163
	143

	159
Blue will play Bar/21 7/3*(2)	155

White will play Bar/24 13/12(3)	162
	139

	158
Blue will play 24/12(2)	139

White will play 24/18*/12(2)	158
	115

Final Position	134
Blue is ahead in the pipcount	133

I just noticed that, for the record, I need to modify the caveat slightly, as shown in bold below. (Otherwise, there is a twin solution with Blue's last move being 21/3 8/2.)

Each side plays three times. Blue gets hit twice; nevertheless, in the resulting position -- in which there is no blot in the outfield nor in Blue's inner board -- he is ahead in the pipcount.
