I'm writing an EPD (Extended Position Description) parser and I have a doubt about what numbers means at end of "predicted variation" opcode.
Look the follow EPD sample:
rq2r1k1/5pp1/p7/4bNP1/1p2P2P/5Q2/PP4K1/5R1R w - - bm Nxg7 BT-2630.1; ce 182; acs 0; acn 106652; pv 1.Nxg7 Kxg7 2.Qxf7+ Kh8 3.Qh7+ Kxh7 4.Rf7+ Kg6 5.Rf6+ Bxf6 6.h5+ Kxg5 (38.748) 112.9; c0 depth=8
As its possible to notice, the opcode pv
ends with numbers (38.748) 112.9
. That
I started from the article in the Chess Programming Wiki. There I found some related materials, like the PGN specification, that have a more elaborated EPD documentation an some links to EPD entries examples. However, I can't find any explanation about the meaning of the numbers.
Does anyone have some material with a more elaborated documentation about the EPD (or PGN) format?
