This question began an interesting discussion on handicaps for engines that play against GMs:
This led me to wonder, are there differences in handicaps in terms of how we measure advantage?
For instance would a material advantage be preferable to space or tempo advantages?
Not sure what the success metric would look like, but i'd like to see the mean permutation on what degree of material advantage places the odds 50/50 for engine vs GM. Then compare that board layout to what tempo advantage would be needed to place the odds at 50/50.
Perhaps if we don't have engines that emulate GMs, we can just use lichess records?
