Bug: Spectators can see the arrows. It is a way of cheating.

i dont think its a bug for people who watch games like to see people do it. you cant have 2 open at same time on same account can they go and use something else yes. but for ffa show arrow stay the same but for teams it should be a option you can click to not show in settings

-1 Let the arrows stay for spectators! Barely an advantage, to know what move the opponents consider (if someone cares to "cheat"), as it's still a mind game with full information given. The arrows makes the games watchable. Without arrows, the games are not as fun as an independent activity.

If you have one account, you can't be on live chess in two browsers at the same time. Not even on another laptop. If you have more than one account, then you are already violating the rules.

I can have more than two windows open at the same time. once I was chatting in my clubs, playing a game, and watching a live stream on chessTV.

He means that you can't have two windows open that are BOTH on the live chess server. The server automatically cuts one of them off.

then this could tempt people to open another account

But then chess.com will find out and then close both of the accounts. They can find out by looking at the IP address. Who would do so much just to look at arrows anyway? Most don't even use the arrows.

This is intended and not a bug. If this proves to be too big of a problem, then I think they might get removed, but for now the arrows are there for the spectators to enjoy.

@Martin0, please look at https://www.chess.com/clubs/forum/view/suggestion-teams-mode-ui-improvement
battleMind24 promised to fix it at the beginning of November. It is time to fix it now.
"Yes, we are aware of this, we will implement features that will prevent users from abusing this. Right now it's not a problem as most team games are not viewable yet (ratings haven't caught up). I think a delay might help prevent this."
Now we can see team games in the Top Games list. There should be a noticeable delay for the spectators at least.

Thanks for that link @BabYagun, I remembered battleMind said something, but not exactly what or where. I really don't know more about this topic than you do. I stand with what I said though. It is not a bug, but might get removed since it can be abused.
Personally I like seeing the arrows as a spectator.

Being restrictive is not the way to go. I would rather not see my opponents' arrows anyways, since that wouldn't make it as fun while I'm playing. As a spectator though, it's so much fun to see both teams have conflicting ideas with arrows!

Even my partner's arrows sometimes distracting me too much, seeing my opponents arrows would be even worse, especially on another window... Also, another window most likely (3/4 chances) will be rotated in the wrong direction, so these arrows are pretty useless with the current time control.

1- I tried to go on Four player chess on two tabs because I couldn't get a game. When I put Four player chess on the second tab It disconnect the first tab cause it said it detected a second account.

Well, as battleMind24 said, it is possible to make a delay and show the game to spectators with that delay, and let them see all the arrows. But now it is a way to cheat.
The "full information" is not that full if you have limited time to think. And the current time control does not allow you to think deeply. If you see the arrows of your opponents you get their idea and spend your time to find a solution (attack or defense). If you do not see the arrows then you first need to understand the idea of their moves and then find a solution. When you have 10 seconds per move it is a big advantage.
Spectators can see the arrows. It is a way of cheating. People just open another browser window and spectate their own game to see the opponents' arrows.
Please hide the arrows from spectators. Thanks.
