This collection has 49K games with human players 2530+. Most games are from from 1998 to the present. Deleted are blindfold, blitz, simultaneous, draws thru 20 moves, wins thru 30 moves, duplicates/twins and "[FEN" positions. I suggest using at least 6 occurrences of a move before including it in your book. It will make your book smaller but on the other hand the chance of a serious book error is less. I also recommend to NOT use book learning if more than one engine is sharing the same book.
