Well, not that few. That's interesting, actually. From 18, using Lc0 at temperature say 0.3 or 0.4, and regular Komodo (with variety) on say 4 threads (both engines randomize well and consistently), a 2-mover (4 plies) book can contain in excess of 1,000 unique, reasonable, fairly balanced positions, and that's not bad as an opening set.lkaufman wrote: ↑Tue May 14, 2019 4:30 amThe reason I don't like your Drawkiller openings (either for testing or to play myself) is that opposite-side castling is not the norm in chess. I'm sure they make for interesting games, but the emphasis on pawn-storms and direct attacks on the king makes it too different from normal chess for me. It's just not representative of standard chess, where positional play is critical. So far my tests indicate that the 18 positions from chess960 that allow normal castling on both sides are also much less drawish than normal chess, without the above objection. But, only 18 positions, too few!pohl4711 wrote: ↑Mon May 13, 2019 11:09 amHow about trying my Drawkiller openings?!Modern Times wrote: ↑Sun May 12, 2019 6:35 am Yes FRC is the prime candidate.
The 50 positions was from the Rybka forum more than 10 years ago:
"Stefan Pohl has created a set of 50 shuffle chess positions, which can be used as an opening database for testing. There are NO castlings possible, and the set does NOT contain any Chess960 positions. 50 positions allow engine matches with 100 games (with switching sides per position)."
Anyway I stuck with chess960.

They look like this: (Kings on opposite side of the board, Queens not on the same line, all non-pawns still on row 1/8. Only 5 of 16 non-pawns not on their normal position...
That gives very, very low draw rates...(nearly halved, compared to classical opening sets) take a look at the testing results on my Drawkiller-site. So, Drawkiller is much better, than FRC. And Drawkiller has much more different positions, than FRC.)
