Strangely here, latest releases of Stockfish (+zysygy) don't find Rc8+ in less than a minute.
If you play the move then the engine will immediately see its strength though.
Earlier release (14/01/2014) spotted the move.
[D] k2N4/1qpK1p2/1p6/1P4p1/1P4P1/8/8/8 w - - [/D]
Same here with Nc6 (Stockfish likes Nxb7 with 0.00)
Any reason why?

My copy of stockfish detects Rc8 on depth 15. I don't have any problem with that.

Whoops. Nc6 is not detected, not even on depth 48 or so.
But when i try this move for myself it detects its usefulness quick as a flash.
Therefore this is really notable, i think.

Re: Test suite for Stockfish
This failure is related to null-move pruning. The latest Stockfish with null move search disabled finds the move almost instantly:Andre wrote:

Same here with Nc6 (Stockfish likes Nxb7 with 0.00)
Any reason why?

Latest Stockfish with null-move pruning disabled:Andre wrote:[D] rk1b4/p2p2p1/1P6/2R2P2/8/2K5/8/5B2 w - - [/D]
Strangely here, latest releases of Stockfish (+zysygy) don't find Rc8+ in less than a minute.
If you play the move then the engine will immediately see its strength though.
Earlier release (14/01/2014) spotted the move.
Any reason why?

Re: Test suite for Stockfish
Maybe an idea is for SF to run a very quick search with null-move pruning disabled...then switch null-move pruning back on.
That way it won't miss these type of positions.

Re: Test suite for Stockfish
I think Uri Blass experimented quite a bit with how/when to best utilize null-move pruning. Perhaps he will reply and elaborate.voyagerOne wrote:Maybe an idea is for SF to run a very quick search with null-move pruning disabled...then switch null-move pruning back on.
