Four Player Chess Strategies

Always try to have flexible pieces. In good games, nobody loses on time, but unfortunately, only about 3/4 of games are "good." If something like this happens, you will have ample opportunity to go and take their king, while others might not. 

The thing I hate is whenever you push your queen pawn to try and promote it into a queen-pawn, the player that is next to go, often uses its queen pawn to stop your pawn or something.

Well moving your pawn to the center too early in the game is not the best idea. People on the side might try to checkmated you or take your pieces while you try to promote. One game a player got 2 queens but I pawn stormed the center while the other player were flanking him with knights and taking away files with their bishops and he was the first one to lose. Surprising now is'int it?

Personally, I don't prefer to exchange pieces at the opening. Even avoid offering exchange chance to your oppennents. I try my best not to attack any of my oppennents, because the situation is not very clear at very beginning. Local fighting between you and one of your oppennets will only lead the other two oppennents prepare more to fight. And we are not really ready to fight. It is a bit similar to appeasement. Moving out too earily strongs pieces like queen or bishops is not a good idea for me.
In middlegames, my principle is to attack the stronger oppennents and try to balancing the whole game. Because coperating to checkmate a weaker oppennent will probably let your allies get the 20 checkmate points. So I often withdraw my pieces before the oppennent will be nearly checkmated. It will be difficult to beat your ally after he checkmates and gets the 20 points.
Particuly, I don't even take the pieces back during the exchange offered by the weaker oppennent. Then he will realise we have the same target, the dominant oppennent in the game.
I try not to trap my piceces in a local fight, because this game board is so large that sometimes it is very hard for the pieces to reentry another attack. But of course, if I find out a checkmate in one step, I will do it to earn the points. Otherwise, I ignore the combinations and will never care about the kings in exile.

I just played a game of 4 player chess and it is so hard. 

any good strategies for diamond wall antichess?

getting ur queen out is only a way to lose it when you get checked

I like 2 fianchetto and goble up free peices, i do not trade bish for qween(do not ask me why, i just want advantage. and castels early, then i get the rooks and qweens 2 the center and push pawns, with the pawns supporting each other and rooks and qweens protecting them, why my opponents are focusing on each other, i just push pawns and win the game.

I have found that the opponent opposite of the board from you is your biggest ally. If they fall you have 2 opponents either side of you looking to take easy points and fending off 2 opponents is not fun.

Never castle 

For you it might be a strong difference plan but because in the castle the Queen of the other team in your Right side ( if you castle in Queen side ) and Left ( when you castle King side ) can play against you and when you busy different the other players can attack your smaller pieces. So remember when you castle take a Bishop or a Knight to go with you .

The player to your left is far more dangerous than the player to your right.

Is there a rule that if you completely strip your opponent of any material you get points?  Yesterday when I captured my onlybremaining opponent's last pawn-queen and bared him I suddenly got +30.  I was playing yellow and I was left one on one with green (the other 2 resigned and timed out).  I had king and queen, green had king and pawn-queen.  On this images pawn-queen checks my king, I put my queen between them, pawn-queen takes, then my king takes and my score suddenly goes from 37 to 67.  Is it because i bared my opponent, or is it something else?

I Usually push my center pawn to promote and then play defense

Excellent guide and suggestions, thank you very much.

move ur queens bishop pawns first then get ur queen out

How could i win in 4 player chess

Yesterday I discovered that if one opponent is under check from someone else and you move your pieces in a way that they can't escape, you get the +20 points for check-mate even if you didn't attack the king directly.
