As Marco shown LMR condition appears in only 3 lines in search.cpp. Finding them, even if you are unfamiliar with Stockfish code takes about 1 minute (supposing you have some chess programming experience, which is more than true in Ed's case).Sean Evans wrote:And you are 12-years old Peter?

And going one step further, would someone do it for me?
Seriously, I don't have MSVC and don't want to go through that. I exclusively have used the "Digital Mars" compiler in the past and that one is not compatible with MSVC and/or GCC source code.

I have an eng-eng match running now, SF 1.8 vs SF 1.8 (no LMR). Long time ago I did the stuff.
