Multiple Valid Strategies

MoveEvalStyle / Strategic Idea
d4+0.58Classical Dominance: Occupying the center to restrict Black's pieces.
h4+0.43Aggressive Flank Attack: Probing the kingside to weaken the g7's shelter.

Different paths, same destination: While d4 is the most principled and popular choice (found by 37% of players), the engine also loves the spicy h4. Your choice is the solid, positional foundation of the opening, whereas the alternative seeks to create immediate chaos on the kingside. Both are objectively excellent!
