DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

1. I couldn't find anywhere in the rules that opponents are OBLIGED to give each other passwords after the game.
I gave my password, but in return, I received nothing but insults.
How can I make my opponent give me the password to the save files after the game?

Of course, this isn't written anywhere, so you don't have to, as I see it. You can always say that you forgot and deleted the file with the password.

2. If both opponents want to start claiming towns FIRST, how do you determine who claims first?

If the colors are indicated in the draw, then the blue player starts claiming. If the colors are not indicated, then the order of claiming is determined by the draw.

3. Regarding auto-wins. What's the difference between a misclick and another click? In any case, it's a mistake. Why is it considered good sportsmanship to give an auto-win for a mistake?
A mistake is an element of ONLINE play. If you give an auto-win for a mistake, then it's no longer online, but offline :).

Isn't it hard to understand? A misclick is not a gameplay factor, but a random, technical one; it can happen to anyone. For example, I had a situation where the heroes in battle got stuck for a moment, and the grand units rushed to the middle of the field, or a hero from the chain rushed in the other direction due to a misclick. I always give an auto-win in such a situation because it can happen to me too, and I believe that I would also be given an auto-win.

But in chess, if you touch a piece, you have to move it - is that bad sportsmanship?

If the game is played in person, then of course, you touch it, you move it, because there is an opportunity to think about the move. In this case, touching a piece will be a gameplay mistake, not a technical one. But on the internet, misclicks often happen when the mouse slips, and the opponent puts the queen under attack. In such a misclick, I also allow the opponent to make a move.
