Piece odd starting position

Does someone already build a pgn file for cutechess in order to run knight / bishop / rook / queen odds.
I guess the idea is to let the piece be captured by one of our knight and go back to starting position. Done for white then for black and use the book sequentially...

Re: A complete 2000 lines of code engine

Minic 1.19 is now released

I shall be a little stronger due to some history (included CMH) tuning
Some UCI fixes about pondering, but probably still not ok

Re: CMH question

In Minic, I was using a [Piece_with_color][to] history table I'm now trying a [color][from][to] history table and a [Piece_with_color][to][Piece_with_color][to] counter history table I wonder if I can use a combination of the 3 scores to build history score ... You're doubling the size of your CMH ...

Re: CMH question

Thanks. That's what I understood. But I still don't get why Xiphos is using index -1 in its stack (and not -2 for FMH). Because indexing starts at zero. CMH is i=0, and FMH is i=1. I think I get it now ! CMH is about a reply to an opponent move while FMH is about a continuation to our previous move ?

Re: A complete 2000 lines of code engine

Are you planning to implement ponder support, sooner or later? Well, I must admit I am not a pondering fan. I am more in the "give the engine all the threads" community. But in fact it is already here, but I still have to check it, I wonder if it's always working well (you will tell me !) ... In xb...
