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!

Unsafe checks 

Introducing a new multi-purpose penalty related to King safety, which 
includes all kind of potential checks (from unsafe or unavailable 
squares currently occupied by some other piece) 

This will indirectly detect and reward some pins, discovered checks, and 
motifs such as square vacation, or rook behind its pawn and aligned with 
King (example Black Rg8, g7 against Kg1), 
and penalize some pawn blockers (if they move, it allows a discovered 
check by the pawn). 

And since it looks also at protected squares, it detects some potential 
defense overloading. 

Finally, the rook contact checks had been removed some time ago. This 
test will give a small bonus for them, as well as for bishop contact
