What is a good counter to the Van't Kruijs chess opening?

A good counter to the Van't Kruijs opening (1. E3) is to occupy the center early with 1...e5. This move establishes a strong pawn presence and allows for quick development of pieces. Following up with moves like ...Nf6 and ...d5 can help to challenge White's position and create opportunities for active play. Alternatively, 1...c5 can lead to a Sicilian-type setup, aiming for counterplay on the queenside.
