The Traxler Counter-Attack (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5) ignores the threat to f7 and counter-threatens f2. Instead of defending, Black plays 4...Bc5 — one of the most audacious moves in chess.

The Traxler (also called the Wilkes-Barre) is Black's aggressive answer to the Ng5 attack on f7. Instead of playing ...d5 (the standard response), Black plays 4...Bc5, threatening Bxf2+ and ignoring the Nxf7 threat. If White takes on f7, Black gets a devastating attack. The resulting positions are incredibly sharp and tactical, with both kings potentially in danger. It's an excellent surprise weapon.
The Traxler Counter-Attack is named after Czech priest and chess player Karel Traxler, who introduced the audacious 4...Bc5 in a game against Karel Reinisch in 1890. The line is also known as the Wilkes-Barre Variation in the United States, after the Pennsylvania city where it was analyzed independently. For most of the 20th century, the Traxler was considered a dubious novelty, something that might work once in a casual game but would not survive serious scrutiny. Its reputation improved when analysis showed that after 5.Nxf7, Black's attack is genuinely dangerous and may even be objectively sound with correct play. The line has gained enormous popularity in the internet age, particularly at the club level and in blitz, where the shocking nature of 4...Bc5 catches opponents off guard. Modern engine analysis has confirmed that the Traxler provides legitimate compensation for the sacrificed material, making it a respectable surprise weapon at all levels.
The Traxler is a pure counter-attacking concept. Instead of defending f7 after 4.Ng5 (the standard response is 4...d5), Black ignores the threat entirely and plays 4...Bc5, threatening Bxf2+ and creating an immediate crisis. White faces a critical choice: take on f7 (entering Black's prepared complications) or play more cautiously. After 5.Nxf7 Bxf2+ 6.Kf1 (or 6.Ke2), Black sacrifices material for a massive attack on the exposed White king. The key idea is that White's king cannot castle and Black's pieces develop with tempo toward the attack. If White plays 5.Bxf7+ instead, the game is less sharp but Black can get reasonable play. The paradox of the Traxler is that the 'safe' option for White (not taking on f7) often gives Black an easy game, while the 'aggressive' option (capturing) leads to positions where Black is the one attacking. This psychological dynamic is what makes the Traxler so effective in practice.
Pawn structure is almost irrelevant in the Traxler because the positions are entirely tactical. After 5.Nxf7 Bxf2+, the position is completely open with pieces everywhere and both kings potentially exposed. If the game does calm down (which is rare), Black is typically down a pawn or exchange but has active pieces and attacking chances. The central pawn tension (e4 vs e5) usually resolves early through tactical means. In the 5.Bxf7+ Ke7 lines, the structure is slightly more stable but Black's king position means strategic considerations are secondary to concrete tactics.
The Bxf2+ sacrifice is the opening's signature move, forcing White's king to f1 or e2 where it becomes a target. After Kf1, Black follows with ...Qe7 threatening the knight and preparing ...d5 with tempo. The ...Nd4 fork idea is a recurring theme, attacking c2 and e2 simultaneously. If White's king goes to e2, the ...Nd4+ check combined with discoveries can be devastating. Knight sacrifices on d4 and f2 appear in many lines. The ...d5 break opens the center when White's king is still uncastled, creating tactical chaos. For White, the key defensive idea is returning material to consolidate, for example giving back the f7 pawn to get the king to safety. The Nxh8 retreat looks tempting but often leaves the knight trapped.
The Traxler does not have famous practitioners at the elite GM level since top players rarely face 4.Ng5 in serious games (they prefer 4.d3 or the Giuoco Piano). However, the line is enormously popular among club players and online streamers. Eric Rosen, GothamChess (Levy Rozman), and other content creators have featured the Traxler extensively. At the correspondence level, the Traxler has been analyzed in great depth and shown to provide genuine compensation.
The Traxler is a focused opening with a relatively small number of critical lines, making it efficient to study. Start with the two main branches: 5.Nxf7 (the most common) and 5.Bxf7+ (the safe option). In the 5.Nxf7 lines, learn both the 6.Kf1 and 6.Ke2 responses and the correct attacking continuations. The concrete variations are essential here since one wrong move can turn a winning attack into a losing position. Practice calculating the tactical sequences until they become automatic. The Traxler is perfect for spaced repetition drilling because the critical moments are concentrated in moves 5-12 and you need instant recall of the correct continuation. Openings.gg lets you import the key Traxler lines and test yourself on exactly these critical decision points, which is much more efficient than replaying full games.
Modern analysis suggests the Traxler provides genuine compensation for the sacrificed material, especially after 5.Nxf7 Bxf2+. It may not be fully equal with perfect play from White, but the practical difficulties White faces make it a legitimate weapon. In correspondence chess with engine analysis, the Traxler holds up surprisingly well. It is certainly more sound than its reputation suggests.
The Traxler can be fun for beginners who enjoy tactical, aggressive play, but it requires precise calculation in the critical lines. If you are willing to study the key variations (there are not many), it can be an effective weapon. It also teaches important attacking concepts like piece coordination and king safety. Just do not rely on it exclusively since it only arises after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5.
The simplest way is to not play 4.Ng5 at all. After 3.Bc4 Nf6, you can play 4.d3 (the quiet Italian), 4.d4 (the Scotch Italian), or 4.O-O. If you do play 4.Ng5, the critical test is 5.Bxf7+ Ke7, which avoids the sharpest Traxler lines while maintaining an edge. Many players simply switch to 4.d3 to avoid the Traxler entirely.
After 5.Nxf7 Bxf2+, White must choose between 6.Kf1 and 6.Ke2. After 6.Kf1, Black plays ...Qe7 and ...d5, building a strong attack against the exposed king. After 6.Ke2, Black has ...Nd4+ with dangerous complications. Both lines require precise play from White, and mistakes are punished immediately. Black often has enough compensation for a piece in these positions.
The Traxler only arises after the specific move order 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5, so it depends on your opponent playing 4.Ng5 (the Fried Liver setup). At club level this is quite common, especially among players rated 1000-1800. At higher levels, White more often plays 4.d3 or other moves, making the Traxler less frequently relevant.
4...d5 is the standard and objectively sound response to 4.Ng5. The Traxler (4...Bc5) is riskier but offers more winning chances for Black since it puts immediate pressure on White. Many players learn 4...d5 as their main defense and keep the Traxler as a surprise weapon for blitz or when they need a win. Both approaches are viable at the club level.
