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 16061598b - new version best chess engine

Don't insert pv back into tt 

This code was added before the accurate pv patch, when 
we retrieved PV directly from TT. 

It's not required for correct (and long) PVs any more and 
should be safe to remove it. 

Also, allowing helper threads to repeatedly over-write 
TT doesn't seem to make sense(that was probably an un-intended 
side-effect of lazy smp). Before Lazy SMP only Main Thread used 
to run ID loop and insert PV into TT.
