Did people try replacing LMR by pruning

[Michael Sherwin]

Stockfish 1.6:

Code: Select all

// Move count based pruning
          if (   moveCount >= FutilityMoveCountMargin
              && ok_to_prune(pos, move, ss[ply].threatMove)
              && bestValue > value_mated_in(PLY_MAX))
              continue;

I am glad to see that the idea survives!

Toga used this general idea also - that was the first place I remember seeing it. But I have not found it useful, myself.

I believe that my testing of it and posting about it precedes its use in Toga!
