So best idea... Move Q(4,7293696964969649169`6391649126969)
4-Player Free-For-All Infinite Bulldog Event Nuke Paint Capture the Flag Chess!!!

Here's a different orientation for free for all
(I've updated the description board, was originally the Morgarten setup)

I like the second orientation and your proposed rules. Events shouldn't be allowed to be used right after another event to prevent confusion and let the first one gain traction.

Lets add some bulldog pieces to fix that, I'ma add witch & time thief, any other bulldog pieces anyone'd like to play with?

If we do do events since I am not Martin I only have 25 events at my disposal to choose randomly from.
The title says it all! This game was HolographWars idea. Your goal: BLOW UP (or just plainly capture) all the other flag holders (if you can find them
)!!! The bombs start on the queens, and the queens move normally! Players are: HolographWars, thegreatauk, SuperSam1, and rychessmaster1.
We can discuss rules before beginning. Here's an idea, instead of exploding everything in a 3x3 box, there will be a paint explosion, coloring everything in radius the color of the player with the bomb carrier, without destroying any pieces! Therefore transferring control of the pieces over to the player who had the bomb holder! And you can only use each bomb once, and when it's used it respawns somewhere random on the map in a 34 block diameter! And if you capture (or get control of) all 4 flags you win!
The bomb explodes only if the bomb holder captures a piece. If the bomb holder itself is captured it will not go off, but will be transferred to the capturer! On your turn, after you move, you may choose to pass the bomb to any adjacent piece (even opponent pieces). A piece may only hold one bomb at a time! A piece can hold both a bomb and a flag simultaneously.
Board before adding witch & time thief:
Board after adding witch and time thief:
Pawns promote if they can manage to move 8 squares beyond the front rank of pawns! (so for example, blue pawns promote at rank 10)
Who goes first will be chosen randomly and play will go clockwise!
Here's Capture the Flag rules:
If the flag holder is trapped in a box (i.e. can't move an infinity distance in ALL 4 directions) for say... 4? rounds, then that player is considered captured & illuminated! Of course this rule doesn't apply to pieces that can't move as far as they want (knight, hawk, pawn...)
Custom Events rules:
You may, at any time start an event! You are limited to 1 event (1 per person), and the event will last the entire game! The event is chosen at random and will change some rule about the game - a full list of all events I will be using can be found here!
If a player has not used their event and they die, their event is immediately called! And at the time there are only 2 players left, any events that still remain will instantly be called! (This will make it a little more intense for the last 2 people)
The Time Thief's special move would only undo 1 person's move (i.e. the move made by the piece the time thief captured), it would be a pain to the other players for time to rewind up to 3 moves ago.
