Posts from Let's talk about our Red Rush strategy...

3.1. Red-rush is prohibited: the player playing as red is prohibited from attacking on the first day of the week with reinforcements purchased on that day:
a) on the blue Castle (even if the Castle is not guarded);
b) on blue heroes or guarded mines, if the presence of reinforcements can affect the outcome of the battle or losses in the battle for either player.

The concept of red-rush does not apply when the heroes of opposing players are on opposite sides of the Portal or Underground Gate during an attack, if red cannot see where the blue hero is.

Clarification 1. Reinforcements are considered to be:
troops that appear at the beginning of a new week in the dwellings of the player's cities (villages) or in cities (villages) of a human or computer opponent captured on that day;

Clarification 2. The following are not considered reinforcements and can be used without restrictions:
troops not purchased in the previous week;
troops from neutral cities and villages captured on that day;
troops arriving with purchased heroes and heroes from freed prisons;
troops from Outer Dwellings ("caches") and troops from Summoning Portals;
troops from Pandora's Boxes, Griffin Conservatories, Serpent Nests, Seer Huts, Refugee Camps.

Clarification 3. It is allowed to upgrade any troops.

Clarification 4. If it is impossible to distinguish old troops from reinforcement troops (mixing in a hero or in a Castle), it is considered that reinforcements are lost in battles with neutrals. Until the reinforcements are mixed with old troops, they are considered reinforcements, regardless of the losses of the old army. *

Clarification 6. In a game involving more than two human players, the rule applies consistently to other colors (blue-rush, brown-rush...).
In a game with player alliances, reinforcements also include the reinforcements of the ally. **

I reread the rule and realized that I put the checkmark in the wrong place. I am voting for points 2, 4, and 6.

It turns out that I voted for the ban on Diamond... It was a misclick, if that's the case, I'm for unbanning everywhere.

Why does red get such an advantage? Explain. It's a different story in the trading phase, where red pays.

5.1. The so-called "red rush" is prohibited, meaning that a player playing with the red color is not allowed to attack on the first day of the week with reinforcements purchased on that day:
a) on a blue Castle (even if the Castle is not guarded)
b) on blue Heroes or guarded Mines, if the presence of reinforcements can affect the outcome of the battle or losses in the battle for either player.

To ensure that the opponents are on a more or less equal footing, either allow Blue to buy out the growth (which will appear in the Castle, not in the mine), or have both fight without growth, or Red must ensure a chain of supply for its growth (i.e., first capture a Castle, and then transfer new troops there).

So, does PP remain forbidden for HL+U? How do you deal with the blue color in the late game then?

actually, what are the advantages of blue besides replenishing mana and the ability to attack with an increase on the first day of the week, on top of your already purchased increase? (considering that this is quite problematic on XL+U) And what's wrong with attacking on the first day after collecting from hidden locations and portals? The main advantage still lies with red.

I raised the issue of red rush, and I believe that my question about red rush remains unanswered.
I wasn't asking why it was banned, but why it was banned in this particular way.

It is not yet clear what exactly prevents blue from defending cities if they are valuable to him.

And if blue defends, then red can no longer attack with an increase. Why should additional difficulties be created for red?

Firstly, the goal - "to give blue the opportunity to buy out the increase" - is a dubious goal. Whether or not blue will have such an opportunity should depend on how the opponents played up to that point.
But with the current wording, where there is a special approach to cities, it turns out that blue may not defend cities at all, and red must still deal with chains.
And if he doesn't figure out the chains, he won't be able to, for example, take an empty intermediate city with his last hero in the chain and settle there with an increase. And blue will strike back precisely with an increase.

In general, I already wrote that this is a matter of tactics. Banning/allowing rush attacks changes the game, and that's it. You need to clearly know how the rule is formulated and think about how to benefit from it.
