 - **3D chess**: [3D](3d.md) generalization of chess, possible are also other dimensions (4D, 5D, ... maybe even 1D?).
 - **antichess** ([suicide](suicide.md), ...): The goal is to lose all men or get stalemated, rules are a bit changed, e.g. castling and checks are removed and taking is forced.
+- **balanced alternation**: Variant proposed in one [game theory](game_theory.md) paper (along with analysis and evidence for the claim of course), attempting to minimize the white's first move advantage with only a very slight rule change: second and third half move switch their order. I.e. white moves first, then black moves TWICE, then white also twice, then the game continues normally.
 - **chess 324**: Chess with randomly modified starting position to prevent opening theory and draws, similar to chess 960. Here queens, knights and bishops are randomly shuffled in the start position with the condition that bishops must be on different color squares (no symmetry of position is required). Advantage against chess 960 is that otherwise the rules (i.e. basically castling) stay exactly the same, so basically any chess engine can also play chess 324 without modification.
 - **chess 960** aka **Fischer's random** (nowadays also "freestyle chess"): Starting position is randomly modified by shuffling the non-pawn rows (with these rules: king must be between rooks, bishops on opposite colors and black/white's positions are mirrored). The rules are the same with a slight modification to castling. This was invented by Bobby Fischer to emphasize pure chess skill as opposed to memorizing the best opening moves, he saw the opening theory as harmful to chess. Chess 960 is nowadays even advocated by some to become the "main" version of chess.

+{ I was thinking about a variant that would completely remove the white's first move advantage and here is my idea: let the players make the moves simultaneously. In real life this can be done for example by players writing the moves on a piece of paper, then revealing them. Of course we'd have to address conflicting situations such as both players moving their kings so that the new position would be illegal. Perhaps the turn would be successful only if the two moves performed in either order would result in the same, legal position. If the turn was unsuccessful, the attempt at a turn would repeat and let's say after 3 unsuccessful attempts the game would be a draw. ~drummyfish }
