Re: Nice EG fortress

I'm not necessarily saying that I trust engines in this kind of study, but 12...Ne8 seems quite inferior to other moves. Every engine I tested shows the score going from at least -8 for Black to near draw with that single move. [D]7k/4N1nq/8/7p/5BbP/8/2p2N2/2K5 b - - 0 12 It's likely that other move...

Re: Rebel Book Draw?

FWIW, I tested several engines on the position before White decided to repeat: r2qr1k1/1bp1bppp/p1np1n2/1p2p3/3PP3/1BP2N1P/PP3PP1/RNBQR1K1 w - - 5 13 The scores ranged between a few cp either side of 0.0 up to +0.5 for White, with the best move being either Nbd2 or a4. Therefore, Black agreeing to r...

Re: Rebel Book Draw?

This is a very well known variation of the Ruy Lopez, even very strong human players repeat moves at this position sometimes. If white wants to win he has to break this repetition, and play something else than Ng5. I guess the human playing white was just satisfied with a draw. When a book is based...

Re: Rebel Book Draw?

Yes, that is what the log file shows. But I definitely said something incorrect. This is the ProDeo book. I assume my implementation is correct, however, in that I simply send a FEN to the book code and if it returns a move I play it. Perhaps I should be checking for repetition moves returned from t...

Rebel Book Draw?

Today, Myrddin played six games on ICC against a human rated ~2150. Myrddin won five of the games, but one was a draw. The curious thing is that all of the moves Myrddin played in that draw were from the Rebel "mainbook" book. [Event "ICS rated blitz match"] [Site "chessclub.com"] [Date "2018.10.02"...

Re: Mediocre engines (like mine) v GMs

It's not often that I get to see Myrddin (CCRL rating 2390 on one CPU) play against strong humans. Thankfully, ICC gave me a free membership for a couple of months. There have been five games against humans in the GM category, and Myrddin easily won all of them. I still find this amazing, but perha...

Re: Mediocre engines (like mine) v GMs

FWIW, this was the most interesting (i.e. closest) game: [Event "ICS rated blitz match"] [Site "chessclub.com"] [Date "2018.08.31"] [Round "-"] [White "Atlus"] [Black "MyrddinComp"] [Result "0-1"] [WhiteElo "2511"] [BlackElo "2372"] [TimeControl "180"] [Annotator "19... +0.79"] 1. e4 e5 2.

Re: In Praise of The King

From the image, and the personality name, I can see that you're using a custom personality. Did you choose the settings yourself?
