French defense, fantasy gambit

WhiteNEW

Who wondered what the fantasy would do against the french defense ? Let's find out in this gambit line which goes against every principle of the french defense for black. Be warned, this opening is hard to play and may transpose into a lot of lines. Prepare yourself to learn a few openings while learning this one.

French Defense

Black

The French Defense aims to challenge White's central control immediately, typically leading to closed positions, unbalanced pawn structures, and strategic counterattacks on the queenside.

The Kerkhof Attack - exd4

White

A great opening all the way up to 2000+ Elo-rating. It's a very simple opening that largely bypasses the middle game.

The Kerkhof attack -Nxd4

White

This opening is for players up to 2000+ Elo rating. It requires very little theory and relies on the key idea of pushing the d-pawn to d4 before the opponent expects it. It largely skips the middlegame struggle to transition straight into an endgame or winning position.

Modern Defence

BlackNEW

The Modern Defense is a coiled spring of hyper‑dynamic counterplay. Black invites White to build a center, only to strike back with venomous pawn breaks, fianchetto pressure, and piece activity that explodes at the perfect moment. This is an opening for players who trust flexibility over dogma, counterattack over symmetry, and precision over panic. The Modern doesn’t fight for the center early — it lets White overextend, then tears the structure apart with …c5, …e5, and the deadly …f5 thrust. If you like setups that feel calm on the surface but hide tactical violence underneath, welcome to the Modern Defense.

What is the Opening Trainer?

The Chessigma Opening Trainer is a free chess opening trainer that teaches real repertoires move by move. Pick a course, play your side's moves on the board, and the board answers back with what opponents actually play at club level. A coach explains the idea behind every move as you go, and when you miss one, you replay the line until it's automatic. Each course also comes with a written guide covering the main variations, typical plans for both sides, and the traps worth knowing.

Which opening should you learn first?

With White, start with the Italian Game if you like open, classical positions, or the London System if you want one setup that works against nearly everything. With Black, the Caro-Kann is the most dependable answer to 1. e4, the Sicilian Defense is the ambitious one, and the King's Indian Defense handles 1. d4. Gambit players should look at the King's Gambit or the Fried Liver Attack.

Frequently asked questions

Is the Opening Trainer free?
Yes. Every course is free to start: the opening guides are free to read and the first lines of every course are open to everyone, with no account needed. Signing in saves your progress, and a Supercoach subscription unlocks the full line set of every course.
Which chess opening should I learn first?
Pick one opening for White and one for Black and stick with them. For White, the Italian Game or the London System give you a clear plan from move one. For Black, the Caro-Kann against 1. e4 and the King’s Indian Defense against 1. d4 are solid, teachable systems. One well-drilled opening beats five you half know.
Can I train openings as Black?
Yes. The Caro-Kann, French Defense, Sicilian Defense, Scandinavian Defense, Pirc Defense and King’s Indian Defense are all taught from Black’s side of the board, anti-White-system courses included.
How is this different from watching opening videos?
You play every move yourself. The board answers back with the opponent’s most common replies, a coach explains the idea behind each move, and when you slip you replay the line until it sticks. Recall practice beats passive watching for openings, which are mostly pattern memory.
What happens when my opponent leaves the main line?
The courses spend most of their time on exactly that. Each one covers the sidelines and the punishing replies to common mistakes at club level, not just the theory line a grandmaster would play against you.
