Blunder up on Lichess for a couple of hours

Post by algerbrex »

If anyone's interested, since I've exhausted my test queue for now, I've put Blunder up on Lichess for the afternoon, running the latest dev version, which should be around 2700 Elo at bullet-time controls: https://lichess.org/@/blunder_engine

Feel free to play it against your engine or play it yourself. Any feedback on the playstyle is of course appreciated and welcomed, since as I've pointed out several times before, I'm not a great chess player.

To keep game quality up I've limited it to playing 2 games concurrently, so if it doesn't respond right away, check back in a bit as its likely wrapping up some other games.

I'll likely have it up pretty late, probably until around: 11-12PM EST.

The top humans in bullet are clearly stronger than 2700.
The bullet leader is GM alireza2003 with rating 3302 so I wonder why the rating of blunder is so low(I cannot believe that it is weaker than humans in bullet time control).

Well, I think it has a lot to do with the available playing pool for engines like Blunder. If you look on somewhere like the CCRL, Blunder's rated close to 2700. And this is because of the playing field and the ratings of the other engines. But on somewhere like Lichess, the average rating of many bots, even bots rated 3000+ Elo on the CCRL like Zahak, are so low because of the lower ratings of the playing pool. So there aren't many rating points to gain.

Even for bots running Stockfish, which also skews many engine ratings to look weaker than they actually are, how many strong, titled players are playing them and giving them a chance to gain more rating? I'd imagine not many. As a matter of fact, I had the pleasure of an IM playing Blunder a couple of times, who was rated 3000+, and he off-handly commented he didn't play engines because he doesn't enjoy it. I don't think many of the strong/titled players on Lichess are interested in playing bots, especially with a lot of them just running Stockfish.
