Two Knights Attack, Mindeno Variation, Exchange Line

With 4...Bxf3, Black resolves the tension created by 4. h3 at once rather than retreating with 4...Bh5, which leads to sharper and more theory-laden positions. The price is the bishop pair, but Black keeps a compact, healthy pawn structure and avoids the forcing lines in which the h5-bishop can be harassed by g4 and Ne5. The position after the capture is a transitional one: White must recapture, and almost every game continues 5. Qxf3, developing the queen with gain of time. The alternative 5. gxf3 is rare, damages White's kingside structure, and scores poorly in practice, with Black winning a clear majority of those games.

After 5. Qxf3, Black's usual choices are 5...e6 and 5...Nf6, completing development behind the d5-pawn and relying on solidity to offset White's two bishops. The resulting middlegames are positional rather than tactical. Engines assess the line as roughly balanced, and in online play the results are almost evenly split between the two sides.
