If you're looking for a defensive system that will allow you to play strong chess openings without spending massive hours on rote memorization to counter the many of possible opening lines at white's disposal this old book, A Black Defensive System for the Rest of your Chess Career by G.M. Soltis may be for you. This focuses on defenses that have similar pawn and piece structures no matter what openings are used by white. i.e. The Caro Kann against e4 and the Slav against d4. GM Soltis Soltis shows that there are remarkable similarities between the Caro-Kann (to defend e4) and the Slav (to defend (d4), and that both systems can often evolve into similar or identical positions, thus enabling one to focus more of their time learning the familiar positions for both white attacks rather than two completely different defenses.

This is not a magic formula for success, but will allow you to play solid, time tested openings on the black side, saving time on your clock, and hours of preparation and study. Add this black defensive system to a asymmetrical opening by white with fewer mainline defences such as the King's Indian Attack, and you'll have a complete opening system that will serve you well for many years to come.

That book is at the used book store down the street.
2 dollars 🤔 maybe I'll check it out.

One plus for this approach is that although this is a classical approach the defenses are not as popular these days. That means it is quite likely your opponent will not the positions as well as you.

Looking at the masters rhp game explorer, it looks like h6 is the best reply.

I see you caught someone who played e6.

I hate playing against the advanced variation so quit playing the French.

On my database there are 1,969 games. The move, number of times played, average fide rating, and score to white was:

4. ... h5, played 1194 times, (2,317) 59.1%
4. ... h6, played 552 times, (2292) 59.5%
4. ... Qb6, played 110 times, (2430) 46.3%

@BigDoggProblem

Thanks. You are right I was thinking of retreating the bishop to h7 which according to the rhp game explorer is losing. According to the explorer black's best move is to retreat back to c8, d7 was good as well.

One has to be careful reading too much into results by percentage, for two reasons.

1) The cause of a loss could be a blunder after the opening.
2) A line can be thought good for Black, but then someone finds a strong novelty for white and renders the previous results less meaningful.

Edit: and there's also:
3) Some opening databases don't properly calculate th ...[text shortened]... results. In other words, you'll score well, as long as your opponent cooperates and keeps it a Caro.

@DeepThought

Why h5 instead of h6? Playing h5 just allowed white a nice place for his bishop.

Did not really work in that game. Thanks, at least now I see it prevents g4.
