3. dxe5
[edit | edit source]White accepts the free pawn. This comes with tempo on Black's knight, so Black's must decide where to move it.
3...Ng4 is the mainline Budapest. This saves the knight and prepares to recapture the pawn. The next few moves revolve around the defence of or attack on the e5 pawn. After 4. Nf3, the Adler variation, White usually can't bring enough defenders so allows Black to take the pawn back and prioritises their piece development instead. Alekhine advocated 4. e4, giving the pawn back immediately without a fight. In the mainline, 4. Bf4, the Rubinstein variation, White does have the choice of hanging onto the pawn, but only if they decide it is worth having doubled c-pawns themselves.
The alternative is 3...Ne4, the Fajarowicz variation. Black sees no urgency in recovering the pawn and would rather prioritise activity.
