And what if the opponent started developing incorrectly, so by week 1 day 3 cannot break through this block with acceptable losses?.. ) Is only the current breakability of the block considered? (I mean this: is the gr gbls and wolves tactic really a viable Citadel tactic in the first 2 weeks?..*scratchinghead*) And are acceptable losses 1/3 of the army as Pasha wrote?

I have not yet arrived at a clear understanding of the block criterion by which one can restart.

My current thoughts on the possibility of such a restart.

1st option: a block that is unbreakable under any circumstances on the turn for which a block-related restart can be taken.
2nd option: a block that is breakable, but the Army that remains gains nothing from it (since there are no prospects of recapturing anything using the remnants of the Army, reaching another respawn, or rebuilding).
3rd option: only the 1st Option.
4th option: something else entirely.
