The Clemenz Opening arises after 1.h3 and falls under ECO code A00. This move contributes nothing to development or central control, but it can function as a waiting move — though 1.Nf3 serves that purpose far more effectively. One minor benefit is that it preemptively prevents ...Bg4 pin ideas from Black. A well-prepared White player who knows the theory from both perspectives can sometimes leverage the ambiguity of this move. While certainly inferior to mainstream choices like 1.e4 or 1.d4, 1.h3 is not outright losing, and transpositions into other systems are occasionally possible. Most players prefer to use their first-move advantage more constructively, which explains the move's rarity. Black can simply respond by occupying the center or developing pieces, taking advantage of the tempo White has spent. With 3.2 million Lichess games across all rating levels, it is a moderately popular opening.
