The Hippopotamus Defense
Your first moves in chess are one of the most crucial. These moves decide how the rest of the games plays out. This means that you need to have a strong opening. There are many famous openings like the Sicilian defense, Ruy Lopez, Queen's Gambit, etc. The Sicilian defense has an incredible success rate, the Ruy Lopez destroys the opponent's pawn structure, and the Queen's Gambit take control of the center of the board. The center is the most important place on the board.
What about the lesser-known openings? Some less popular openings can be very deadly if you don't know how to counter them. One of these less-known openings is the Hippopotamus Defense. The Hippopotamus Defense behaves like a hippo, waiting under the water until the right time. Black has to wait until they move most of their pawns to the third rank and most of their pieces to the second rank. This lets Black set up a defense such that Black can flexibly adapt to whatever White throws at them. This opening really got popular after Boris Spassky used this opening in the 1966 World Championship against Tigran Petrosian.
