Win With The Caro-Kann by Sverre Johnsen and Torbjørn Ringdal Hansen
Gambit Publications Ltd
Price €25,45
ISBN (13 digits):

The famous chess author Grandmaster Torbjørn Ringdal Hansen and companion chess trainer Sverre Johnsen, provide the reader of this book
with original move to move ideas and highly instructive model games.
This book reads easy and the suggested repertoire lines run in big lines as:The Korchnoi Variation:1.e4 c6 2.d4 d5 3.Nc3 dxe4 Nf6 5.Nxf6 exf6 {50pages}and as second alternative line the so called Bareev,Capablanca Variation:1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Bf5 5.Ng3 Bg6 6.h4 h6 7.Nf3 e6!?
This relatively new move is known as the Bareev Variation and is one of the key moves of this repertoire book {good for around 55 pages of highly instructive text!}
In the Advance Variation black goes for the move 3….c5 but as second alternative the rare and never seen move 3….Qc7!?
Interesting enough we see the Queen’s move Qc7 also back in the Exchange variation,1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Bd3 Nc6 5.c3 Qc7!
This move forces white to find a plan B as Bf4 needs extra preparation.
In the Panov Attack we see the move order 1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nf3 g6!?
And as second choice simple take the pawn with 4.c4 dxc4!
The move from Goldman 1.e4 c6 2.Nc3 d5 3.Qf3 is as we an learn from both auhors not such a good move,although it has been played by some strong players.
Again it is all well explained.
Included are al kind of rare second moves but 2.Ne2 scores best and  was even played by Kasparov and Short,when they where teenagers.
Torbjørn Ringdal Hansen & Sverre Johnsen,do do not only bring you back in the time with Horatio Caro and Marcus Kann,but both old masters could never have imagined so
seen such a hypermodern study on there Caro-Kann!
Conclusion: Highly recommended also for the more experienced player!

Komodo Dragon 2 comes with a number of engine variants. The standard version offers maximum playing strength. For analysis with multiple variations, on the other hand, the “MCTS” version is recommended. In addition, this version offers an exciting feature: you can have the move that offers the best chances from a practical point of view displayed in the analysis. The standard version, on the other hand, always expects the best possible play from the opponent, and that is therefore clearly the first choice, especially in correspondence chess. In addition, the engine can be switched to the variants “Attack”, “Beginner”, “Defence”, “Endgame” in analysis and in the game. Includes current Fritz 17 program interface and six months ChessBase Premium Account.
On the site I did find the following information:
Dragon 2 is a huge strength improvement over Komodo 14.1, the last pre-dragon release, about 210 elo in standard mode, at CCRL blitz time control on one thread based on 10,000 game direct matches. With four threads, the gains were 198 elo in MCTS and 184 elo in standard mode. The improvement is due to the embedded neural network providing much more accurate evaluation and also in some sense gaining an extra ply or so of search by “seeing” some tactics that a normal eval won’t spot. Our testing also shows that Dragon is especially strong in Fischerandom (960) chess, which was confirmed when Dragon won the TCEC FRC 2021 championship. Dragon also won the 2021 TCEC Swiss championship (normal chess). We believe that Dragon will play in a more human-like style than standard Komodo since it relies on learning what actually works in games rather than just on pre-assigned values for eval terms.
Although Dragon 2 is only slightly stronger than the initial dragon version in standard mode, the MCTS mode when running under Windows is dramatically improved, about a hundred elo. Also the MultiPV play of standard mode is dramatically improved from the initial dragon release, again by about a hundred elo! Based on our testing, we now believe that Dragon 2 in standard mode is the strongest engine for analysis on most computers when displaying more than four lines of play at once. A new feature with Dragon 2 is “MCTS Optimism”, which allows the user to make Dragon “trust” its own judgments more while being less confident in predicting the opponent’s moves. Other features added since Komodo 13 include Armageddon mode, more levels, Personalities, and Auto-Skill. Standard mode is usually the stronger mode objectively, while MCTS mode is usually better at setting problems for human opponents as it does not assume perfect defense. Skill levels have been adjusted to use the Dragon NNUE without much change in the strength of a given skill level; we think this makes the skill levels more "human-like".
Conclusion:My first conclusion:Thrilling to play with!
