The Exchange Line is 4.h3 Bxf3, where Black answers the question at once and takes the knight. White must recapture right away, choosing 5.Qxf3 for quick development or 5.gxf3 for a stronger grip on e4, and Black then builds the ...e6 and ...Nf6 chain against the two bishops.

Key ideas for both sides
White
- Take back 5.Qxf3, the engine's first choice, then Be2 and a d3-d4 plan with the queen eyeing d5 and f7.
- The 5.gxf3 option keeps the queen home, supports e4 with the f3 pawn and prepares d4 and Qd3.
- Never skip the recapture. The engine shows 5.Be2 losing heavily after ...Bxe4, because the f3 bishop escapes with a pawn.
- Against a later ...c5, be ready to open the center while your bishops are the stronger minor pieces.
Black
- Against 5.Qxf3, play ...e6 and ...Nf6 so d5 is protected twice and the queen hits only pawns.
- Use ...Nxe4 to trade pieces in the center if White spends time on d3 and d4, as the first engine line shows.
- Against 5.gxf3, strike with ...c5 after ...e6 and ...Nf6, hitting d4 while White's king is uncastled.
- Put the dark bishop on d6 or b4, where it does the work the traded light bishop cannot.
Plans and pawn structure
After either recapture, Black has a sturdy chain on c6, d5 and e6 and no light-squared bishop, while White has the bishop pair. With Qxf3, White develops smoothly with Be2, O-O and d4, and the queen adds pressure to d5, so Black must be careful about e4-takes-d5 tricks. With gxf3, White's kingside is broken but the f3 pawn holds e4, the g-file opens for a rook, and the king may go long after d4, Qd3 and Bd2. Black seeks ...c5 or ...dxe4 at the moment White's pieces are not ready.
