a modest 5 to 7 elo gain, but now with some of the HekaStockfish presearch code, modified, which I have labeled profound.
The profound (presearch) code does a much wider search early on - I offer two profound settings and they are both simply on and off switches.
As part of my testing , I had determined that the setting should be a higher value as the the time control increases this is done automatically by th e time control selected:
this setting is turned on by default for Honey BlueFish and Black-Diamond and off for Stockfish flavor XIr1 as that version always keep that in sync with cur-dev Stockfish functionally
option name Profound type check default true
the go infinite cand the go depth commands does not use a time control, so there is a second setting called :
option name Deep_Pro_Analysis type check default false which is always off by default.
It is to be used with 15 minute analysis . For longer analysis, say 1 hour , you might be better off using go movetime 3600000 ( or go mt 3600 , mt is in seconds . movetime is in milliseconds
You also now type 's' or 'set' to view all available command line terminal shortcuts
will create and start adding exe's to the release page tomorrow.# Black-Diamond-XI-r1
