The Kadas Opening is an offbeat opening, named after Gabor Kadás. It starts the game with h4. It is also called the Desprez Opening.

Theory[]

The Kadas Opening has very little theory involved, and has some basic lines. After h4, black can play f5, and white's best option is to play d4, creating a Dutch styled opening.

Black could also play h5, which blocks the H pawn from advancing, but does very little in the grand scheme of things. White can counter by making an outpost on g5, if black plays Nf6 and advances the E pawn.

Bishop Outpost on g5

A good option is to play e5 as black, which exploits the fact that White hasn't tried to play in the center. If white continues to play on the sidelines, Black can play e4 and develop the minor and major pieces.

Another good option is d5, which also controls the center. If they are a weak player and they try to get their h-file rook out, you can capture it in a swift move.

If black plays c5, it has the ability to transform into a Sicilian Defense, and white can begin developing quickly.

Gambits/Variations[]

Black can play a rare gambit called the Schneider Gambit, which sacrifices a pawn with g5. It can be used to prevent a kingside castle, but it leads to a disadvantage for Black in the long run if they don't attempt to put pressure on the kingside.

The Schneider Gambit

Another variation is the Koola Koola, an offbeat attack that leads to no strategical advantage, and mostly played sarcastically.
