It was tested again. The old engine passed STC https://tests.stockfishchess.org/tests/ ... 8fc7eb690c and failed LTC https://tests.stockfishchess.org/tests/ ... 8fc7eb690e

It confirmed that new patch is good, but personally I did not test it.

Test it you'll see for yourself

I have no time at the moment.

I don't like the new patch. It's just parameter tuning and in my opinion the new parameters are weaker. In any case, I can't handle it, I prefer to stick with the old parameters for my engines.

You and me both. But in one of my experiments i tried to tune them enough to get draws against stockfish 081023. I could only get 100 draws but winning is another thing. So i gave up on this patch. Its tiresome
