Center Game: von der Lasa Gambit: what should White play?

In the Center Game: von der Lasa Gambit, White faces a critical decision regarding how to develop the kingside while Black holds a temporary pawn advantage on d4. The most effective continuation according to engine evaluation and master-level practice is Nf3, which prepares for kingside castling and exerts immediate pressure on the center. This move is chosen in 56.1% of recorded games, maintaining a nearly equal evaluation of -0.07.

The primary continuation with Nf3

The move Nf3 is the standard response in this position, appearing in over 783,000 recorded games. It serves the dual purpose of developing a minor piece and preparing to challenge the d4 pawn or support an advance to e5. The main line typically proceeds with Nf3 Nf6 e5 d5 Bb5 Ne4, where White seeks to disrupt Black's coordination in exchange for the gambited material.

Alternative development via Ne2 and Nh3

While Nf3 is the engine's preference, Ne2 is statistically the most frequent choice in the database, played in 70.0% of games (approximately 10,000 instances in this specific subset). This move aims for a different setup, often leading to the sequence Ne2 Nf6 Nxd4 Nxe4 Bxf7+ Kxf7, which results in a highly tactical position where Black's king is displaced. Another alternative is Nh3, played in 50.0% of the remaining sample, which avoids blocking the f-pawn but carries a lower engine evaluation of -0.87.

Strategic considerations for White

White's strategy in the von der Lasa Gambit revolves around rapid piece activity to compensate for the missing pawn. Moves like Nd2 and Qd3 are rare, each appearing in only 0.1% of games, as they are considered less efficient for maintaining the initiative. The placement of the c4 exerts significant pressure on f7, a recurring theme in the tactical lines following Nf3 or Ne2.
