Wouldn't be surprise if this is a duplicate (related even more related), but:
Obviously there are two main ways to lose a game: Blundering it away in a single move or be slowly crushed by a better player without knowing what's happening.
We now have a giant database of games and engines that can tell us who is on top at any time in a game, and they could answer my question: which way is more frequent?
Very evidently, the answer might depend on ELO or ELO difference, so you can take that in account too.
