Ukraine

Some think this current offensive is a diversionary move to entrench RuAF in spots and the main offensive will happen soon in another area. Interesting theory
I suspect after you damage infrastructure and leadership as much as they have, you make use of the inherent inefficiencies created. Forcing them to react across long distances makes sense in that regard. But I don't have all the intel to know if it's the best play.

I've learned from chess, don't make moves because you hope your opponent reacts in a certain fashion. Make moves which will force them to react how you want or at least not open you up to that same exploitation.

But this is real life. There are significant differences from a war to a rather balanced board game.
