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 16041611 - best chess engine

Stockfish - chess engines UCI

Previous version chess engine Stockfish 

Author compilation -

Fix last search info carried over to mate position 

When starting search in a mate or stalemate position, Stockfish does not 
even care to reinitialize and start worker threads. However after search 
all threads are checked for the best move. 

This can lead to bestmove and info beeing carried over from the last 

Example session: 

setoption name threads value 7 
go movetime 4000 
position startpos moves f2f3 e7e5 g2g4 d8h4 
go movetime 4000 

Actual output is like (almost always): 

bestmove e2e4 
info depth 0 score mate 0 
info depth 20 seldepth 29 multipv 1 score cp 28 [...] pv e2e4 
bestmove e2e4 

Expected output / output after fix: 

bestmove e2e4 ponder e7e6 
info depth 0 score mate 0 
bestmove (none) 

Resolves #623
