In Response To: 21S-43X question (Nack Ballard)

In reply to Nack's "Z or X" question, I would hitherto play Z in all three positions. I don't want to lose ground by getting hit back after 6/2*, and the loose hit on the two point also commits me to covering it when not hit.

I think X increases in value as White's offensive power increases. Having seen from the rollout that 21S-43[X=Z], the tempo-hit in 41S-43X must be better than 41S-43Z. After 41S, White is almost certain to make a good offensive point including better chances to point on Blue's split man, so taking that away has more value.
