Re: Raid
Sad, sorry! 
I wanted to see what's new in Raid and I can't find anything. Only one code in the search was not taken from "Stockfish dev by Stefan Geschwentner" but the old line was kept. I don't know why I should use Raid? The author should (this is my opinion) tell people that Raid = Stockfish dev, and that the only thing implemented is the Polyglot book and the Sugar AI learning file. And this is not the author's own work, but copy & paste from SugaR AI. Compare yourself, I have attached both search.cpp files:

Raid v2.78i_X is 99,999% identical in search to Stockfish dev, Author: Stefan Geschwentner Date: Sun Oct 8. The only difference is in Step 20 (search.cpp) where RAID prefers an older Stockfish dev. entry, see at the bottom.
STOCKFISH DEV:

Simplify collection of bad moves for history updates.

SF Gschwentner:
// If the move is worse than some previously searched move, remember it, to update its stats later
if (move != bestMove && moveCount <= 32)
{

capturesSearched[captureCount++] = move;
else
quietsSearched[quietCount++] = move;
