Indian Defense: Budapest Defense, Adler Variation trainer

Back to the opening, all openings to practise or my repertoire

Type a move and press Enter: e4, Nf3, O-O, or from and to squares like g1f3 (e7e8q to promote). The board is also played with the mouse.

Practise the Indian Defense: Budapest Defense, Adler Variation

The Adler Variation of the Budapest Gambit is 1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 4.Nf3. Play White's moves of the line from memory — 1. d4 Nf6 2. c4 e5 3. dxe5 Ng4 4. Nf3 — and the trainer plays Black's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Indian Defense: Budapest Defense, Adler Variation page, or pick another opening in the opening trainer.
