Game in 10hrs

because very ezy game i love 4 players chess.

You don't need a computer to tell you that 4-Player Chess (4PC) is more than just twice as complex as its 2-player counterpart. The game of 2-player chess has been around for centuries, and it's been decades since us mortals could defeat the best of what computer engines can do. Stemming back to Kasparov's 1997 defeat at the hands of IBM's Deep Blue, man is no match for machine in one-on-one chess. So the question arises, how do engines perform in 4-player? The resources of the 4PC community are far less than what's available to the teams behind DeepMind's AlphaZero, Romstad, Costalba, & Kiiski's Stockfish, or Komodo, by Kaufman, & Dailey, although that hasn't stopped some AI-savvy programmers from building some very talented engines. Currently, there are 3 engines, each in various states of revisions and self-learning. As of yet, the engines are only learning how to play as teams. FFA and Solo are much less predictable, and the challenge of programming an engine increases exponentially as the element of luck and randomisation increases. These engines have the ability to host rated or casual teams games within 4PC, and will only ever be partnered with themselves. Aside from the fact that it's a bot controlling the moves instead of a human, the gameplay, rules, ratings and mechanics are the same as usual. The games hosted by the engines will be given a custom title (i.e. "Phoenix Challenge"), and are available to any player. If you see these games, and want the chance to play against an engine, join to try it out! Prior to any of these engines being developed, our very own developer from 4PC, @spacebar, created a two types of bots for testing purposes. These are the Mr.Random Bot and 4-Comfuter, which do not play games on their own, nor can they be invited to rated games. Let's meet the engines! Terminator by @Tony Programmed in C >10,000 lines of code Alpha-beta searching engine, similar to non-neural 2PC engines Comments from the creator: Its development started in March 2019, and the first version to play online was from October 2019. When the current version plays against the Oct-2019 version, it wins over 95% of the games, so it has improved a lot. However, it is still not unbeatable in games with human players. I think it's very likely that some other engine or engines will surpass TeamTerminator in 4PC teams strength in the future. @TeamTerminator1 @TeamTerminator2 Machina by @kooser6 Programmed in C++ 3174 lines of code Follows standard UCI protocol Comments from the creator: I am currently working with different pruning methods, and different depth extensions to get the strongest play. Also I just started working on a NNUE version of machina just like Stockfish NNUE. In the next couple of years you can expect a 3000+ rated machina. @TeamMachina1 @TeamMachina2 PhoenixZero by @omatamix Programmed in C 2513 lines of code Comments from the creator: PhoenixZero only has 110 thousand self-play games (compared to AlphaZeros 40 million). With 4 player chess being so complex, it might be a while before PhoenixZero becomes unbeatable. In the future I plan on building a computer which can train the AI’s network faster. I am currently working on making a MuZero implementation of PhoenixZero. @PhoenixZero1 @PhoenixZero2 A 4th engine, as a collaboration between @omatamix, @kooser6, and @GTSWPM150 is in the works, under the title of ZivaZero. One area of focus for this new project is openings, and in particular, discovering new, more dynamic teams openings. As of right now though, we'll have to wait in anticipation! Many thanks to the creators and collaborators on these projects, both for their investments in 4PC engine creation, and specifically for their contributions to this article. I'm sure I speak for all of us in the 4PC community, when I say we are excited to see what the future holds.

I think the current way it works with double check which includes a player that resigned/timed out is weird and should be removed. I saw a game where 2 players were remaining, but there was also a king left from a player that resigned. Normally trying to capture that king as quick as possible is a good idea, but it was a queen ending where the player with initiative could create a lot of checks against the enemy king which included double checks against both kings. After being behind almost 20 points the score lead quickly shifted and when he finally stopped giving checks and took the king the game was pretty much over. One more thing that is kind of unintuitive is that the double check does not count if you leave a piece threatening a king that left, but counts if you move a piece that was already threatening the king to another square that threatens the king. I'm overall not super enthusiastic of these rules since it really messes up the maximum score you can get, but at the very least I do not think double checks and triple checks should count the kings that has resigned.

1. What happens if Player 1 moves so that Player 3 is now in discovered check from Player 2? Can Player 2 take Player 3's king and get the points, and Player 3 is just dead? 2. What happens if Player 1 uses his rook to pin Player 3's king on the back rank, and Player 2 brings his rook down to do the two-rook checkmate? Who gets the points? Player 2, since he's the one who actually put the king in check? 3. What happens if Player 2 moves a piece so that Player 3 is now in discovered checkmate from a Player 1 piece? Who gets the points? Player 1 for being the one threatening the king, or Player 2 for making the move that resulted in the checkmate? These sorts of questions are part of the reason we always allowed leaving yourself in check and moving into check in our three-handed chess game, and someone had to actually capture the king to kill you. That's not the only way to solve the problem, but it's an easy way. And in our three-handed version where you took control of the pieces of the person you killed, it sometimes resulted in interesting strategies when people would intentionally leave themselves in check to force another player to bail them out; that strategy wouldn't usually work as well in a points-based system, though.

I'm seeing a new bug that I think is different from the disconnect bug that others are reporting. I've been playing 4-player-chess for a number of months, and this bug just started in the last week or two -- I think it coincides with the release in which we had to agree to new terms of service or rules about teaming. Anyway, the bug symptom is as follows: You are playing, your turn comes, and you make your move, but the client doesn't recognize the move, and your clock continues to tick as though you have not moved. You get no message about disconnecting, and it appears as if you are still fully connected. It feels as if the client side code is getting confused when the mouse moves a piece and then abandons the move (such as moving to an illegal square) and then tries again, or holds the move for a couple of game cycles before completing the move... as one might do when thinking about the move. To be clear, this is happening to me mostly in games in which there appears to be no disconnect issue.

my teammate (flower3oclock) last move that was not in check gave up the rook.

Everybody. The last solo Wheel of Fortune has got only... 2 games, 2 games ladies and gentlemen. And sometimes normal Wheel of Fortune got 300< games! lol. So, a friendly reminder. Hope you guys enjoy playing Wheel of Fortune and the solo one, it's not bad

So just today, I noticed in game, my moves do not register correctly during a specific time. I played 2 games and noticed this happening in both. One was a 4min FFA, the other was a Chaturaji. What it is: When my turn is next, and I left click and hold a piece, and hover it over a square that I want to move to (during another players turn) ..., and then once it is my turn, and I then release the left click, my move will not register at all. It will send the piece back to the original square. This loses time and has never happened before. I only noticed this today. I have restarted and reconnected and it still happens. What it is not: 1) Pre-moving. When completing a full pre-move, the pre-move does register correctly and fast, as soon as it is your turn. 2) Moving normally (if you have not clicked a piece yet until your turn) - Once it is your turn, and you have not left clicked, you can normally move a piece, after the previous player has moved and your time is activated. - Any insights? Is this a bug, or an I missing something in a specific setting? Thank you

https://www.chess.com/variants/4-player-chess/game/54740247 This is an interesting game where I get destroyed by having my opposite playing a horrible opening where none of his pieces had any meaningful development AND passed up more than one opportunity to win material. The player to my right sacrificed most of his material to take me out. It did not work out for either of them. The player to my left won the game, as I thought would be the case. Maybe I am too conspiratorial, but everything just went against me in that game and yellow and green destroyed any chance of winning that game. Any thoughts?

Is there a way to find 4pc games that were played on the old server (pre-merge) or have they been deleted into the ether?

so y'all like 4 player chess right? y'all heard of "anarchy chess"? well over decided to mash the 2 together in this form here https://www.chess.com/forum/view/general/anarchy-chess-chaos-edition come along and join the fun and chaos here comrades > : )

https://www.chess.com/forum/view/off-topic/anarcy-chess-form-game?page=1#last_comment I want this to get more publicity, go do stuff
