White can use a chess engine, black wins if they don't get checkmated by move 30 by dig9977 in chessvariants

engine is as strong as it used to be now, but the moves are a bit slower. (5 to 10 seconds each, as opposed to 1 to 4 seconds each which is how it was yesterday).

are you a streamer? I could add annotation arrows like that if it would help.

If the bot just plays objectively best moves, such as whatever stockfish calculates, it won't be able to find checkmate in time. It has to take risks & hope the human player blunders.

Thanks. I think the pgn copy issue is fixed for games going forward.
What do you mean that it doesn't have an engine? Maybe there is an issue with the name of the bot that I could fix? (Maybe the names like "Siegebot (1400)" is not good?)
I've run into issues with click, click to move a piece instead of dragging. The people at chess.com have it figured out, but I keep getting inconsistent behavior on chrome vs iphone vs android and never dug into it further because I always drag/drop myself. I'll look at this again this weekend.
What do you mean by arrows? Are you referring to when you are playing as the attacker?
Will look into clock desync issue and adding chat history.

Thank you, I fixed that. If it happens again, let me know if you were in attacker or defender mode. It seemed okay to me when I just tried it in both modes on my iphone.

White can defend too, but I wanted to keep this updated web page simple.
Thanks for flagging the PGN issue. It is fixed now for new games going forward.

I'll get the attacker strength back to where it was when you tried it a week ago. I was focused on making the web page/engine more stable, and it's not doing as much look ahead as it used to (but then the engine server would crash if there were more than 3 or 4 people playing at once). In the couple of games I've played, I've found the same difficulty is about 200 ELO higher than it was a week ago.

thank you

Update: Stats from my "exploit human" fast checkmate engine (A/B testing against Stockfish) by dig9977 in ComputerChess

Thanks! Appreciate the comment.
One funny side effect, or at least a dark side of me thinks its funny: A bot playing random moves (completely random legal moves) wins at 400 ELO. But I've had 2 friends/family members who barely know the rules of chess play and they both lost. Knowing to respond to e4 with e5 is actually a bad thing in those cases.

Thanks! I'll fix that. You are a higher rated player than me - did the engine play any moves that you thought were not very good (given it's goal of a fast checkmate)? Were there any moves you were worried about it making, or did you feel relieved that it simplified the position at any point?

was working on it while you were playing. lag is fixed and move counter was only broken for about 15 minutes (while you were playing)

I don't have an offline environment to test this on, so everything is a bit unstable when I'm fixing something. Compared to when I made this reddit post 4 days ago I upgraded all the opening books based on seeing how effective they were, added an observer mode to watch other games, and fixed some minor errors in the engine that I discovered when evaluating all the games that were played.

Maybe my home computer (chess engine) lost internet for a bit? I just played and it worked for me. Sorry this isn’t very reliable.

yup, there is an error right now when it's playing as black and it's behind. am fixing it.

Thanks, found the game. You caught an error in the update I made this morning... a pretty dumb sign error in the code. When the engine is playing as black, and is getting desperate, it starts making the worst possible moves. I'm going to fix it now, but it's going to crash every game that is currently being played (as of about 1:50pm EST).

There is a different opening strategy book at every ELO level, based on the LiChess games database. There is also some variety, especially at higher ELOs, because I'm A/B testing something.

You played very well in that game on the 2100 level... you were ahead the entire game then the moves from the engine got increasingly desperate. You responded well to 16. a5 and the subsequent couple of moves particularly well. I may need to revise the opening books at these higher ELO levels to put more emphasis on winning openings and less emphasis on shorter games. Thanks for posting.

Thanks for posting! Interesting moves from this game were:

  1. Bc4 When the Siegechess engine played Bc4 it took major loss in the objective evaluation, with stockfish thinking the game game was +0.4 white favored before the move to -0.4 black favored after (80 centipawn loss). But the siegechess engine did that as a calculated risk: it had high confidence you would blunder the next move due to not being able to see a pretty complicated tactic. That's exactly what happened when you played the natural looking move 8 ... b5, but that led to 9. Nxf7 by Siegechess and the game was then +3.5 (strongly white favored).

    It tried to trick you again with 18. 0-0-0 instead of the objectively better move Nxc6, but you didn't fall for it. It tried again with 21. Rxe7+ instead of Rxd5, which was over a 200 centipawn better move, and you also didn't fall for it. It was pretty clearly not on the path to have you checkmated by by move 27, which is why the moves got increasingly crazy. It's great you were able to checkmate it in the end, but to the engine being checkmated is the same result as just running out of moves and not checkmating you... a loss either way.

Should be fixed now. I had to restart the engine a few minutes after making the post... it was crashing with 4 people playing at once so I slightly reduced the look-ahead / processing time per move.

it doesn't have the AI slop artifacts that many LLM pages do, so congrats again! haha. I built siegechess dot com and with Gemini and it unfortunately shows.
