Hi everyone.

Event chess is a chess variant invented by me. I made the variant about 7 years ago and it has become a variant I constantly revisit with my chess friends between rounds in a tournament. It is based on each player starting one event/game that will change some sort of rule to the game. This means you will go from a normal game to a combination of 2 events (since each player starts one event each). Since there are over 100 events available the possible combinations of events are over 10000, which makes each game very different from each other. Starting an event can pretty much be seen as the same as to start playing a new chess variant in the middle of a game.



You start by playing a normal chess game. There is only 2 additional rules.

1. Each player may once/game start an event during his turn before making a move.

2. A player may not capture more than 2 pieces that are not pawns before starting an event (This is to make sure both players need to starting an event quite early).


When starting an event a random number generator will be used (random.org is used in the forums). Then as long as the event meet the requirements (such as there being at least 1 knight when a rule change for knights is made) that event will start. If the requirement is not met, then get a new number and try another event until an event that fits the requirements is found. It is important that both players understand the new rules for the event. After making sure both players understands the new rules the player that started the event finishes his turn by making a move on the board.


If a chess clock is used it should be stopped when a player announces that he wants to start an event and the clock started again once both players understand the rules. It is ok to stop the clock if you have any question regarding the rules later in the game.


Currently I am the only one with access to the rules for all the events. This is an intended choice by me. The players are not supposed to try to take into account all the possibilities when starting an event, but rather adapt to them when the event starts. This said, some examples is posted at the end of this post. The advantages a player have when starting an event is that it is that players move. This means that player will be the first to react to the new rule changes and this can be an advantage. In general it is a good idea to develop pieces first and then start an event when you do not have a forcing move you need to play.


If someone wants to try this variant, then it can be played in the forums here at chess.com. Just find an opponent and I can set up the forum for you. I can also play if you want to play against me.


I want to add a reminder though that all events are a work in progress and all are not tested yet. Sometimes events get added, removed or changed and I constantly do this to improve the variants. I can not guarantee that all variants are good, but most of them have proved to be fun and interesting to me and my friends. Most games also tend to be decided by playing good rather than being lucky with the random event (although games being decided by luck has happened).
