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!

Use a fraction of king danger in endgame score 

When SF has an attack on the opponent king in one flank, the huge 
midgame -> endgame gradient of the tapered eval prevents us to properly 
evaluate neutral exchanges on the other flank as the current king 
danger score is a pure midgame term. This may affect SF's ability to 
switch to defense in some positions. We add a small contribution 
of the king danger to the endgame score to limit this effect.
