Blog "Chess Engines Diary" - needs a new laptop for chess engine tests

♔ We use for testing only 2 old laptops:
1. Acer - Intel Core i3-3217U ( 5 years old)
2. Lenovo - Intel Core i7-4710MQ is over 3 years old (He works 24 hours a day)
♕♞ A modern laptop that will be designed only for chess engine tests costs (with software) about $ 1000-1200 (4200-4500 PLN). We will no longer invest private money, and chess engine testing costs are big. That is why we are starting the collection for the purchase of a laptop for testing.

♕ Our blog "Chess Engines Diary" is visited by around 2,000-3.000 users daily. If only everyone paid 1 dollar - we will pay the required amount in one day!

Stockfish 17121709 - new version!

Stockfish, chess engine UCI

Rating JCER = 3389

Make staticEval independent of the search path 

Current master can yield different staticEvals depending on the path used to reach the position. The reason for this is that the evaluation after a null move is always computed subtracting 2 * Eval::Tempo, while this is not the case for lazy or specialized evals. This patch always adds tempo to evals, 
which doesn't affect playing strength:
