You'd have to make the points awarded differ with white vs black. World champs wouldn't have been a lot different other than it would end earlier. If you lose a game, you need to win a game to be even. That doesn't change even if you make it 100 points for a win. It would impact multi person events more, but not incredibly. I think some interesting options are things like .7 for draw and 1.2 for win as black. Other options are to make 3 move repetitions illegal (now they're a kind of zugzwang). Last option that I like would be to add a time penalty for drawing in future matches. I think chess needs to become less even, and you could do that in interesting ways if you were willing to mess with the time (or even who moves first) in future matches. Incentives to win now (vs maybe win later) should reward aggressive play early in tournaments and make players who are falling behind more incentivized to fight mid tourney.
