The Grob
The Grob is a bad opening (about the worst) for 2 reasons.
1. It does not lay a claim to the center
2. It weakens the king side (you cannot castle short anymore).
Best openings (especially for beginners) are either e4 or d4 openings. Both directly lay a claim on the center and allow fluid development of pieces.
Thank you but I don't like these basic openings but if they're the best im going to have to give them a try.
Chess is for humans in many ways a concepts (and calculation) game. The 3 main concepts of the start of the game are 1. Develop your pieces and 2. Control the center. 3. Find a safe spot for your king
Good openings adhere to these concepts bad openings don't. The Grob for example sins at least against concepts 2 and 3. Complex (but correct) openings like the English or the Reti do not sin against these rules but it asks a lot more from the player to keep to the concepts.
Openings like e4 and d4 offer more guidance on how to conquer the center and develop and are therefor generally better at least until you have a strong grasp of the principles
