Re: Endgame tablebase generation for newbies

I thought having the King on c6, like so:
8/k1P5/2K5/8/8/8/8/8 w - - 0 1

would also force white to promote to a rook. And while it is faster (DTM2) - 1. c8=R Ka6 2. Ra8# , you can still safely promote to a queen after 1. Kd7 Kb6 2. c8=Q ...

pgn-extract can handle .ctg file ?
No, I don't believe so. I don't use chessbase, but from my understanding, ctg is a book file (analogous to polyglot bin opening books), not a database (cbh)?

Re: Pause calculation / analysis engines

I have never used it before, but I believe Komodo has an option to save Hash to a file to be able to load for later use.
I think in theory, this is what you are looking for?

Re: Utility to Convert chess Database to PGN Opening Repertoire

Same question ! is there a command line tool somewhere ? Since I posted this, I learned about using the --plylimit option flag from pgn-extract. In theory, you could successively use pgn-extract to first 1. Limit Ply (--plylimit), Remove All tags (--notags) 2. Remove Duplicates (-D), Add 7-tag Rost...

Re: mate in 3?

The fen you posted is wrong. You are missing the bishop on g5. It should instead be:

Kn5N/p1p1R3/r3b3/3p1kBp/1N1PrP2/3Qp1nP/2B5/6q1 w - -

For some reason, there are two boards on the website you posted, and one has the bishop on g5, and the other doesn't. That is likely the problem.
