Suppose a game is played, until checkmate, between players of unequal strength, say 1800 vs 2800. What would be the average number of moves be for, say, 1000 games? I also ponder 2000 vs 2800 and 2200 vs 2800? for any time control.
I was thinking to pitch two computer engines, but I could not find any computer vs computer online. Then I tried myself (1750) vs Stockfish level 20. On the 5th attempt, I lasted 40 moves, much longer than Iexpected.
Edit: Edward: Good point, likely knowing I can't win vs machine I was just exchanging all the way, don't remember any more. DM: I was thinking checkmate, as different players will resign at different times. There is question on this site, "Can you resign if your opponent has only king?". Apparently - yes?! Mike Jones: This would be good test likely, though I'm not sure with such discrepancy in rating how many games are there. And I'm not in possession of any. Thank you all.
