In Response To: WI recube for match? (Stick)

I've noticed this year that people in general get a large lead and fail to cube when they should. These same people also don't recube for the match when they should. They're happy in positions like the one posted here, to bring it home safely and be up in the match instead of put it all on the line when they should. I've been trying not to miss cubes like this OtB and I'm happy to strain my arm patting myself on the back that I did cube this.

The score (after 0 games) is: user 4, gnubg 5 (match to 9 points)
