Announcement: Official release of Pedantic 0.3 is now available
I am happy to announce that the first official update to Pedantic is now available. Pedantic 0.3 is a UCI engine that I have tested in both Arena and CuteChess. This release is estimated to be stronger than v0.2 by about 214 Elo which results in overall playing strength of about 2687. I am looking forward to seeing how close my estimate is to the one CCRL eventually calculates.

This version includes the following updates:

• It is no longer mandatory to pass the argument "uci" in order to use Pedantic in a chess GUI. This should alleviate issues where GUI does not provide a method to pass this argument.
• The option MaxThreads has been removed from Pedantic's configuration. This option (or the more standard Threads option) will be re-enabled when Pedantic supports SMP.
• Static Null Move Pruning (Reverse Futility Pruning)
• Internal Iterative Deepening
• Enhanced time management (results in stronger performance)
• Enhanced static position evaluation (2x2 king buckets, enhanced king safety and stronger center control)
• Faster search (shorter time to depth)
• Will now used PEXT/PDEP instructions to enhance move generation if available on the user's system.

Download Pedantic 0.3.

The program shows us a self-mate for black?

From the UCI documentation:
* score
* cp <x>
the score from the engine's point of view in centipawns.
* mate <y>
mate in y moves, not plies.
If the engine is getting mated use negative values for y.

Showing a +M8 at depth 19 indicates that black is being checkmated, not white. Your FEN shows it is white's move. Am I missing something?

Did this position happen while you were in the middle of a game or were you analyzing the position? If from a game, to you have the PGN? I'm not producing the same output starting from your given FEN.

[chessica]

I use Arena, setup position, then analyse

#14 only move Kc3 solves the mate in 14

What is your cpu?

Intel i7-12700K 16GB memory all settings for Pedantic default (other than no Own Book). Concurrent games 6 but Ponder is off so with 8 performance cores should be not an issue.
