I have a collection of checkmated chess positions, in FEN/EPD format. Most of the time, each of these positions contains some useless pieces, that I really want to remove, in the aim of getting cleaner schemes.
Then, I'm searching for a batch possibility to check if my whole chess collection is checkmate or not. Ideally, it would be a tool/solution using DOS/CMD, because I have to clean many FEN checkmates.
I've googled for various DOS chess tools, but in vain. I also searched to use some chess engines (under cmd), Arena/WinBoard, EPD2Diag, PGN-Extract, etc. but also without success.
Here are two examples:
[FEN "3q4/6b1/4k3/4r3/3p2Q1/B1N1R3/5R2/6K1 w - - 0 1"]
[FEN "1K6/1b6/1b6/1P6/7r/7p/7Q/4qN1k w - - 0 1"]
Here, it's obviously both checkmate for White, but knowing I have few hundreds of others, how can I get a DOS batch possibility to check all in once?
