The Chess DAC is a large multi-player chess game where all players can play *both sides* of one large DAC-wide game.
Players bet on the winner (black or white) when they make a move. Each "turn" is an auction where people pay to move a piece. Which ever move has the largest balance is the move that is made. All funds contributed go into a winnings pot and give the submitter either "white shares" or "black shares".
When the game is "won" the pot is divided among the shares of the winning color.
This game as an interesting twist: you can bid on both sides and thus attempt to cause the other side to "make a mistake".
From a gambling perspective the outcome of the game is unpredictable and from a players perspective it poses new challenges. People can create "chess bots" and join a "team".
If someone is gutsy enough they can pay enough to win every auction and "control the game"... there can be many attempts to "game" the "game" and that all turns into user engagement. The game will have a relatively high "rake" which will make it unprofitable to control both sides with high bids and thus forcing people to "pick a side" if they want to win.
The color with less bids (fewer white shares or black shares) has a higher payout-per-share and thus the risk/reward of joining a losing side balances out and keeps the game evenly matched.
I suspect you will have to "pre-purchase" white-shares or black-shares prior to the start of the game and then use those shares to bid on moves in-game. This will prevent new bets from diluting old bets once the odds change.
