Re: Solista CTG Books
NEW, 14 Feb 23: Solista Universal v1.6. + v1.6 extreme.CTG, ChessBase-Format (2 books in the package):
https://solistachess.jimdosite.com/books/
Solista Universal extreme.CTG:
Here are two books in one package (normal and extreme). This book is maximum fun. It plays all known openings, including gambits. But don't worry: all variants have been tested in engine tournament practice. The extreme book also plays very rare lines like 1.g4, 1.b4, 1.e4c5 b4, 1.d4Nf6 c4e5 ...and many more. In the case of moves such as 1.c3 or d3 or e3, a change of move is often attempted on the server, e.g.: 1.e3 e5 2. e4 --> you are playing with swapped colors. That's why I have such moves with a !? provided, which means that these moves are only played if the checkmark under "Tournament book" is deactivated. Otherwise, almost everything comes into play.

Re: Solista CTG Books
Stockfish has mastered the art of drawing even difficult openings!
My test on PlayChess is running. Today is the third day. All openings are currently drawn, except for 1.g4!
I find that 1.g4 is probably the weakest move known in known theory. Of the 4 games played, 1.g4 has lost three. I analyzed and improved a lot, but when Black plays 1...d5 no equalization is possible. Black retains a +1 advantage in each variant until the endgame and wins.
I'm so sorry, but I had to block this move.
But it is all the more gratifying that none of the other openings have lost! Every gambit is a draw, and all rare moves like 1.b4 are also a draw. Everything is a draw for Black too, even after 1e4 g6 or 1.d4 d5 c4 e5 or 1.d5 Nf6 c4 e5. The test continues. I will make all games available for download. My engine plays with 8 cores.

Re: Solista CTG Books
It has really become very difficult to win. Many variants with a pawn up, Stockfish values between 0.00 and +0.50 and a few more +0.70. All this does not win! Without NNUE it would look very different. Some people have tested Stockfish on the server without NNUE, and there have been many loses. Today I finish my test on PlayChess and will report about it. So far only 1.g4 has lost. I could also test 1.f3 to see if that's really weaker than 1.g4. But f3 is nonsensical and without logic.

Re: Solista CTG Books
I updated my universal + extreme book:
https://solistachess.jimdosite.com/books/
This books are maximum fun. It plays all known openings, including gambits. But don't worry: all variants have been tested in engine tournament practice. I played with the extreme book in autoplayer mode on PlayChess.com for three days, and improved all the variants! The hardware had 8 cores. Only 1.g4 had lost. All other variants, which are declared as weak, received a draw! If you absolutely want to play 1.g4, you have to deactivate the tournament book in the extreme book options. Then will all as "!?" marked variants played.
The weakest opening is 1.g4. If black correct 1...d5! plays, then white cannot get an equalizer. In all variants, Black retains a +1 advantage into the endgame.
I am surprised, that not other variant has lost! Every game played with 1...g6 ended in a draw too! All gambits also drew.
I consider the Budapest Gambit difficult to defend, but it managed to draw in the test. An interesting variation (Berlin Defense) begins after the following moves:
DIAGRAM
1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. d3 Bc5 5. Bxc6 dxc6 6. O-O Bg4 7. h3 Bh5 8. g4 Nxg4 *
Stats in the Universal Book:
Why does White win so often? This is where Stockfish seems to misjudge. Far into the middlegame, an advantage of +0.50 is assessed for Black. Then Black (especially in the blitz games) tries to avoid a draw and overruns the position! White just has to wait. My few games with black on PlayChess.com ended in draws.

The variant with 8.- ..., Bg6; 9.- Nxe5 instead of 8.- ..., Nxg4 was already played in 1992 by not top players (probably with a transposition according to 365Chess):

A shallow analysis of SF 15.1 likes 16.- ..., h5 proposed by Mikhalevski two years ago:GM Victor Mikhalevski wrote:The game Giri, A - Tari, A, 83rd Tata Steel Masters Wijk aan Zee 2021, featured an aggressive setup against the Anti-Berlin with 6...Bg4, which was tested a couple of times by the World Champion.
Giri met the text with the principled 7.h3 Bh5 8.g4 Nxg4 9.hxg4 Bxg4 10.Be3, and Tari followed his countryman with 10...Be7. Next, Anish improved White's play in Nakamura, H — Carlsen, M 2020 with 11.Kg2!, instead of 11.Kh1?. Black's first reaction, 11...f5!, was correct, but after 12.Qe1! Bxf3! 13.Kxf3 f4! 14.Bd2 g5! 15.Bc3 Bf6 16.Nd2 he first played the inaccurate 16...Qe7 and then after 17.Rh1 h5 18.Ke2 he committed a mistake, 18...g4? This led to a risk-free position for White, which he led to a win with a series of interesting manoeuvres. Good opening preparation and clever maneuvering allowed the Dutch GM to win comfortably. Black can improve his play by means of 16...h5, when he seems to have sufficient compensation for the sacrificed piece. This means that the line with 6...Bg4 is perfectly playable.
