I have all solved but one today: Q1b4q/2Pp2p1/3P1k1b/6pP/3p1pPp/3P1pBK/5P2/8 w - - acd 51; acs 3840; bm Qe4; c1 "#125"; c3 "Qe4"; ce 2030; id "yacpdb id 193611"; pm Qe4; pv Qe4; I guess that Qe4 is the right move, since the score is very high, but no full solution. Solved: 8...

Re: MRI - Match Result Inspector

Great tool! Some things i would like to see: Report: Window for`Drop` (able to find X score drop in Y plies). Show FEN positions in html report (easier to see/copy the FEN). ... The two points above exist already in Toms Game Analyser and it even has a GUI and eval graphs. http://talkchess.com/foru...

Re: hash collisions

I complained to the Stockfish group that badly formed EPD will cause Stockfish to crash and core dump heinously, eventually filling my disk drive with core files. Their response was: "Don't send badly formed EPD to Stockfish then." I guess we should all expect that the millions of EPD positions we ...

Emit fully decorated EPD (with all the analysis from the logs) for any of the unusual data points found (inverted score, sudden drop, etc.)
