Asso games definitely do not rely on tactical approaches. Perfectly known and tested counters do not work at all. I've been beaten twice by an inferior 4-2-2-2 hexagon with 4-5-1V and I can tell you that I can't remember another loss for me in this situation. Dominated both games but still lost. On the other hand, one of my mates drew twice while being dominated 10-20 on shots twice. Playing these asso matches looks like rolling dices finger crossed. Boring.
