I'll say it again: I realized that the original game mechanics were disrupted precisely in the last battle. Accusing me of cheating or deception is possible, of course, but I've never given any reason for it, and it's at least inappropriate of you to do so. The same applies to Cobra.

Although it's a bit late, I'm not accusing you of cheating or intentionally exploiting the game. I'm just saying that you immediately understood what actually happened (Red's double turn after actual contact). Okay, let's say you didn't realize that something like this couldn't happen in the original game (although I don't quite understand how you could miss that when you just saw an opponent appear, who immediately takes another turn and attacks you). In any case, you saw the opponent in time to make a decision, and the logic of the "Observe Hero" (OH) system on the site is described quite clearly. Perhaps the judges should have specifically warned players about the obvious possibility of such situations and the obvious way to resolve them (replaying Blue's turn). But that's for another tournament. Here, as Redwhite rightly pointed out, the players themselves took responsibility for playing with OH, they set the date themselves, and therefore they should monitor such situations themselves. Moreover, this seems to be the only situation that needs to be monitored manually.

In conclusion, the situation shows that it is not self-evident, and Blue should be given the legal right to disable OH at his own discretion, with a replay of his last turn, if he believes that the delayed information about Red's turn will seriously affect his decisions. Of course, this will add work for the Arbitration Committee (AK) in the question of "did he actually play differently, or did he just take the auto-move after losing?", but such a question will still arise with the current OH logic.
