maybe I'm missing something - we're playing with seasonal rules, which are designed not only for L + U...

Different templates are used for large maps (Spider, 8mm6, etc.). And in these templates, some of the rules differ significantly from those that everyone is used to when playing on regular SM maps. If you play 8mm6 with the mandatory rule of breaking through staggered guards, it will be "crazy," because there are so many guards that in some cases it is simply impossible to determine who is guarding whom and who needs to be attacked. There are many such differences, and if these templates are included in the tournament, it would be good to have rules that are specific to them!
