King's Pawn Game: Wayward Queen Attack: what should White play?

In the King's Pawn Game: Wayward Queen Attack, the position arises after Black defends the central pawn with c6. White's premier continuation here is Bc4, which targets the vulnerable f7 square to set up Scholar's Mate threats while developing the light-squared bishop. This critical move holds an engine evaluation of -0.35 and overwhelmingly dominates practical play, appearing in 96.1% of the 12M recorded games in this position.

The Threat Created by Bc4

The development Bc4 fulfills the central tactical idea of White's early queen sortie, aiming both h5 and c4 at f7. From this position, White achieves a 53.0% scoring rate across 12M recorded games, capitalizing on the immediate mating pressure. An illustrative engine continuation demonstrates how Black parries the threat: Bc4 g6 Qf3 Nf6 Ne2 Bg7. After Black interposes with the pawn, White's queen retreats to f3 to renew the mate threat before transitioning into piece development.

Passive Alternatives and Retreats

Choosing moves other than the main continuation results in a loss of initiative and a worsening evaluation for White. Defending or developing quietly with Nc3 is chosen in 2.0% of games (238K recorded) and sees White score only 40.4%, leading to lines such as Nc3 Nf6 Qd1 d5 exd5 Nxd5 with an engine evaluation of -1.03. Similarly, retreating the queen early via Qe2 yields an evaluation of -1.03, illustrated by Qe2 Nf6 Nf3 Bc5 c3 O-O. An outright retreat via Qd1 scores just 35.9% across 43K games (-1.06 evaluation), while d3 drops to a -1.18 evaluation, as demonstrated in d3 d5 c3 Nf6 Qe2 Bc5.
