@mhouppin I think this PR is related to my PR in Official_Stockfish.

• Fix PvNode bug on qsearch function when alpha == beta - 1 official-stockfish/Stockfish#4575

Can you share your opinion with us in the Marco repository?

• Prevention alpha == beta - 1 in qsearch function for PvNode mcostalba/Stockfish#324

Thank you very much

@mhouppin I think this PR is related to my PR in Official_Stockfish.

No. This has nothing to do with the PR you made on SF's repo. You're literally commenting on a two-year old PR for no reason.

Can you share your opinion with us in the Marco repository?

No. I have other things to do than to engage in random discussions with trolls on the Internet. You already know what I think about this, I already commented on this PR 4 months ago: official-stockfish/Stockfish#4575 (comment)

This is the third time you ping me out of nowhere, and I am really starting to lose patience. If you keep doing this I'll just block you. Please just stop.
