Counteract

Normally from columns: ends Trade and Split Counter Rotate, while the centers Counter rotate and "anchor the (new) trailing center for a Trade". That is, the new lead center does a Cross Run while hanging on to the trailing center. The effect of this is that the trailing center will do a U-Turn Back.
