Chess 2 is a joke with an exponential punchline. The first punchline comes in reading the title. The second punchline comes in reading the rules.
The third punchline comes when you and your friends are all gathered together on a discord call for two and a half hours, crowding around a virtual chessboard like a bunch of grade schoolers playing trading cards at recess, goading your friends on the best strategic approach they ought to be taking, and you’ve all been arguing on whether the pawn ought to ride the king like a horsey for so long that you completely forget that you could have just gone ahead and taken the opposing queen three moves ago, using regular chess rules, you clown.
In this way, the biggest punchline of all is the one that this game places upon us. Chess 2 is a masterstroke, and we are all its fools.
