Changes

1. New and bigger neural network made from 1.2 billion position analyzed with Benjamin 1.1, estimated elo gain ~60.
2. Search changes, estimated elo gain ~40-50.
3. NNUE tuner parameter in Engine Settings. Changing the default of 100% to 125 will make Rebel even more aggressive, 150 up to the point of reckless, values lower than 100 will change the playing style to be more moderate. We tested the value 75 and it gave an extra 10 elo but it was preferred to leave the value at 100 exactly what the learner had created to keep the original Benjamin 1.1 playing style.

• Fabien Letouzey for Fruit 2.1 
  

• Pawel Koziol for Growing Fruit
  

• Chris Whittington for introducing me into NNUE, providing me with the necessary tools and writing the NNUE code.
  

• Rebel 14.1 is released under the GPLv3 licence.
  

There are 2 versions of Rebel 14.1

1. Rebel-14.1-avx2  for modern computers
2. Rebel-14.1-sse    for somewhat older computers.

Use Rebel-14.1-avx2 wherever possible since it runs
considerable faster.

Thank you.
