The 3rd stage of the annual John Van Caneghem Tournament (2007).

I think if there isn't a topic like this, it should be created! Solving interesting problems will appeal to everyone! This will improve our skills!

That's actually a good suggestion... :) I would just suggest formatting it a little differently - like it was done on the League back in the day. It's a shame that topic didn't continue...

The essence is quite simple:

A Blitz Tournament is held, where the tasks are not to complete a map, but to win a single battle. For example, three to five save files are posted, each with its own set of conditions. A deadline is set for solving them, and the results are summarized in a single table. The winner is determined by two criteria: the number of remaining units or the amount of remaining mana... The winner of each save file provides a detailed description of the battle. Well, and the winner of the tournament is the player who takes first place in the sum of all battles, which is generally understandable... :)

This is for those who are bored waiting for the opening of a new tournament...
And for general development... :)

And then you can post the descriptions in the School of Mastery.
