Guys, regarding my comment about using trucks to block, (agreed, probably an extremely rare ocurence), I think you maybe missing my point? I am trying to highlight that a hypothetical use of trucks (or anything else) in this context would be a reasonable tactic to use and not gamey play. Perhaps the tactic might prove costly but, if the manouvre ended up creating a win, why not do it?
My point is, some rules maybe cast in stone but there can be 'grey' areas that those rules push aside?
regards
Peter
