One of the most amusing Chess variants I learned as a kid is the one where white gets the full complement of pieces, and black gets only a king, with the proviso that black gets two consecutive moves and can move through check on the first move. This means that black can capture two pieces in a single turn. While white still wins with optimal play, less experienced players playing white will get absolutely wrecked.
