The 8th stage of the annual John Van Caneghem Tournament (2008).

Well, I agree that I knew about the map longer than others, but if anyone thinks that I won solely because of that, let them say so directly and without any hints!

Indeed, let them say so. I don't think so. My words should always be taken literally, not interpreted for hidden meanings. If there are any doubts, maybe it's worth clarifying them in a private message instead of just ranting here? But it's not difficult for me to give a clear answer here as well. I read your Walkthrough and think it's better than mine; I'm even considering trying to complete this map in 6 days now. The 7-day limit doesn't seem so obvious anymore.

Thirdly, learn to lose and stop making excuses about it being just a fun game!

You're judging by yourself. Take a look at the discussion of the 5th stage of the World Cup and read it. There, the organizer gave the task of quickly building a Grail structure, but he didn't take into account that it requires a level 15 city (i.e., on that map, no earlier than day 12). And the Grail itself could be taken on day 10. When the trick with the level was revealed, I didn't try hard and spend 2 days gathering parameters; instead, I simply built the structure on day 12 and sent the save. Wolf64 won that tournament, who managed to take the Grail only on day 11. But for some reason, when I honestly said that it was possible to act one day faster, and therefore have more parameters later, he didn't start shouting all sorts of nonsense about learning to lose, but instead expressed regret that I wasn't in the mood to properly replay the already completed Walkthrough. Because, indeed, you can play not for the win, but for the sake of the game itself.
