Book: all engine use generic book “ProDeo.bin”-converted for Arena

NNUE-Engines:

• will follow TCEC … https://wiki.chessdom.org/TCEC_Season_20_Rules

Guidelines for use of NNUE at TCEC:

• NNUE code can be used and considered as if it was a library (even if it is not literally one)
• Custom modifications to the basic NNUE code are strongly encouraged,
• It should be considered rather like a starting point.
• All NNUE training data should be generated by the unique engine's own search and/or eval code.

• In the German chess magazine “CSS” (paper edition - year 2004/2005) the EGTB controversy was discussed.
• Those test-results said it is better to do without (the speed of an engine is slowed by 30 per cent when using them).
• Furthermore, not all engines use tablebases.
  

OpeningBook:

• All Engines use their own book if available (For Edition 6 there was own book only for Division A to C, others used Arena mainbook.
