Since you’re here...

... we have a small favour to ask. More people, like you, are reading and supporting our blog: "Chess Engines Diary". And unlike many other sites and blogs, we made the choice to keep our articles open for all, regardless of where they live or what they can afford to pay.

We hope you will consider supporting us today. We need your support to continue to exist, because good entries are more and more work time. Every reader contribution, however big or small, is so valuable. Support "Chess Engines Diary" even a small amount– and it only takes a minute. Thank you.

Chess engine: Stockfish 21100611 (Windows and Linux)



Stockfish - UCI chess engine, compiled by J. Oster
Rating CEDR=3517

Timestamp: 1633514013
Time-management fix in MultiPV mode.

When playing games in MultiPV mode we must take care to only track the best move changing for the first PV line. Otherwise, SF will spend most of its time for the initial moves after the book exit.

This has been observed and reported on Discord, but can also be seen in games played in Stefan Pohl's MultiPV experiment.
Tested with MultiPV=4.
