Use the centre to gain time
In this sample, Black accepts the pawn with 3...exf4. White pushes 4.e5, attacking the knight on f6. The lesson then shows how Qe2 renews that threat and Nf3 prevents the annoying queen check on h4.

2. Nc32... Nf6After 2... Nf6If the logical response ♞g8-f6 is played, we apply our Vienna Gambit — playing f2-f4, heating things up in the center of the board
3. f4






























After 3... exf4White to move. At the board3... exf4After 3... exf4Capturing the pawn with ♟e5xf4 is already an inaccuracy, allowing us to push ♟e4-e5, attacking ♞f6. Attack!
4. e54... Qe7After 4... Qe7Another option is defending ♞f6 by pinning along the "e" file. We respond symmetrically with ♛e2, renewing the threat to capture the knight
5. Qe25... Ng8After 5... Ng8We play ♞g1-f3, preventing the annoying check ♛h4+. Our plan is simple: seize the center, regain the ♟f4, and develop a serious initiative, confidently exploiting Black's lag in development
6. Nf36... f6After 6... f6Black might try to undermine the center instead of developing with ♞b8-c6. In this case, we capitalize on Black's neglect of development by attacking with ♞c3-d5!
