A THREAD FOR NEWCOMERS!

Thank you, brother, for the help. But it turns out I already know all this. (well, except I haven't used item 4) I thought there were some other tricks here. Still, thanks for the info. And slow roads — what are those? Are they depicted on the map as dirt roads?:) Tell me about restarts. In what cases is it taken? And when is it mandatory?

More details on item 4.
3 examples, from simple to complex.
1. You arrive with a hero at a Castle, to restore mana, as experienced players say "to spend the night". In the army: Titans, upgraded Nagas, Gargoyles, upgraded Gremlins. You are sure that no one will attack the Castle on the turn change. You move everyone except the Titans (they have the highest speed among this group) to the Castle garrison and press the end turn button. When your turn starts, you take everyone back and continue moving.
2. Moving with two heroes (usually one scouts, collects resources and such, while the other fights). Before the turn change, IF YOU ARE SURE NO ONE WILL ATTACK YOU (!!!!!) you designate the hero who needs to advance further the next day and give all his troops except the fastest ones to the second hero.
3. A technique used in Heroes 2 by vbn and me (Van Cunningham - Season 7 of 2007) as far as I remember: on the turn change, an enemy hero attacked you. After several rounds of battle and waits, the following situation arose: you have, say, 1 unupgraded Golem, 51 upgraded Gremlins, Gargoyles, unupgraded Nagas. Only your turns are left, everything happens after the wait. And you DELIBERATELY attack the enemy's last stack with the Golem so that the Golem dies. Then you kill it. The point of sacrificing the Golem is so that "in the morning" (the moment your turn begins) your hero moves further (the Golem has a speed of 3, while the upgraded Gremlins have 5!!).

Restart (experienced players sometimes say "rest") — this is a concept from online play. Like "the cards are dealt" — that is, you start — you see what and how. Bron without Basilisks, Gunnisson without the Ballista, and other such "pleasures" — a reason to consider a restart. A large number of shooter guards with a poor respawn (without caches, crypts, and other "goodies") — that is also a reason to "ponder the eternal."
As for mandatory restarts — that depends on the specific rules of a specific tournament ...
