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!

Limit king ring to eight squares 

In current master the size of the king ring varies abruptly from eight 
squares when the king is in g8, to 12 squares when it is in g7. Because 
the king ring is used for estimating attack strength, this may lead to 
an overestimation of king danger in some positions. This patch limits 
the king ring to eight squares in all cases.
