4. Nxf7!? - Pusab Countergambit
The Pusab Countergambit is a variation of the Stafford Gambit, which is a line in Petrov's Defense¹². The sequence of moves is as follows:

'''1. e4 e5 2. Nf3 Nf6 3. Nxe5 Nc6 4. Nxf7'''

In this sequence, white sacrifices a knight on f7 to capture the pawn, leading to an exposed black king¹². This gambit is known for its ability to generate traps, despite being disliked by computers¹².

After 4.Nxf7, black's king is forced to move, and white can gain a tempo by attacking the black king. However, this also leaves white's knight vulnerable and potentially trapped behind enemy lines¹².

Despite the risks, the Pusab Countergambit can lead to complex and interesting positions. It requires precise play from both sides, and a single mistake can lead to a quick defeat¹².

According to lichess.org, white has a win rate of 53% in this line¹². This suggests that while the Pusab Countergambit is risky, it can be effective if played correctly¹².

Remember, chess is a game of strategy and every move has potential consequences. It's up to the player's judgment to decide whether a move aligns with their overall game strategy. The Pusab Countergambit offers an aggressive and tactical approach to the game, but it also requires careful planning and execution¹².
