Yes, after the match you can tell them. But what about during the match? Does this fall under OA? If not, should you tell them?

In match, all players can show his hand… its legal show a counterspell in hand to duress your oponent ^_^

In this case, the “unconscience” part of the player want show it ^_^

Playing with your hand revealed is a legal but poor strategic move, so we should not intervene. I'm really not sure whether I'd assess outside assistance if a spectator pointed it out mid-match, though.

During a match, I would say that it 100% is OA. I believe the meaning of the statement you quoted in your previous post on the previous page is basically that a player is responsible for making a reasonable attempt to hide their hand, but if outside forces deem that reasonable attempt to be not enough then it is the responsibility of the judge and TO to rectify the so that the reasonable attempt is sufficient.

For example, two players are playing a match in a particularly fancy conference hall. The conference hall, because it is fancy, lines its walls with mirrors. Player A is playing against the wall, Player B, the opponent, is sitting facing the wall. Player A is holding their hand such that Player B can't see it from the front, but if Player B is looking in the mirror, they can see Player A's hand clearly and easily. In this situation, I would say Player A is making a reasonable attempt to not reveal his hand to Player B, but due to outside forces Player B can see Player A's hand anyway. In this case, the tournament staff (TO, judges, etc) should step in to block the mirror in some way so as to not reveal Player A's hand to Player B.

So I still have not gotten a satisfactory answer. Everyone is talking about what should be done before or after the match, which is helpful information, but wasn't my question. I'm asking about this situation DURING a match. If a spectator tells them, is it OA? If not, should the judge tell them or is it up to the player?

It's also possible that the next sentence- “players may choose to reveal their hands or any other hidden information available to them”- covers this.

I would argue that, by separating the two sentences, you've lost the context - and leads to the questions you asked. The first quote, about preventing hidden info from being revealed, applies to things like your library, cards that were exiled face-down, etc.

Isaac, I think you HAVE received all the information you need - at least, if you pay attention to posts from the ‘O’fficial sources - to arrive at the answer you're seeking.
