Bishop's Opening: Philidor Counterattack: what should White play?

In the Bishop's Opening: Philidor Counterattack, White reaches a decisively winning position where the tactical breakthrough Qxe5+ is overwhelmingly best. This check claims the undefended e5 pawn while simultaneously creating a double attack against the king on e8 and the rook on h8. Engine analysis assesses this capture at +4.41, giving White a decisive material advantage across the 79,271 recorded games featuring this board state.

The tactical refutation with Qxe5+

Black's move with the pawn to g6 attempted to harass the queen on h5, but it critically overlooked the defense of the center. By playing Qxe5+, White captures a central pawn with check and exploits the compromised diagonal leading toward the corner. Because Black must address the check to the king immediately, the corner rook on h8 is left unprotected and cannot escape capture on the following turn.

Illustrative engine continuation

The primary engine line demonstrates how the tactic unfolds: Qxe5+ Qe7 Qxh8 d5 Be2 Be6. Black minimizes further damage by blocking the check with the queen, allowing White to capture the trapped rook with h8. Even after Black attempts to contest the center with pawns and develop minor pieces, White safely preserves the bishop and remains up a full rook for negligible compensation.

Inferior queen retreats

Retreating the queen concedes all opening initiative and hands Black the advantage. Moves such as Qe2 (evaluated at -0.26), Qd1 (evaluated at -0.66), and Qf3 (evaluated at -0.69) fail to punish Black's tactical oversight and allow the second player comfortable piece activity. The passive Qh3 drops the evaluation to -1.40, as seen in the line Qh3 d5 Qc3 Bd6 exd5 Nf6, where Black readily seizes the central files. Only Qxe5+ capitalizes on the position.
