5.e5! – The Modern Italian Game and Black's Three Response Doors

On the screen tracking the game between Arjun Erigaisi and Laohawirapap, there is a moment most viewers skip in a few seconds. After the opening sequence 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4, Erigaisi does not recapture the pawn as thousands of other games still do. He pushes the pawn to e5. Move five. A thrust so modest that, if you scan quickly through the analysis board, you would mistake it for the hesitation of a player weighing options. But I sat down and rewatched this opening three times — once tracking the tempo of moves, once observing the structure when White holds the initiative, once observing Black's response when forced to answer. That is the method I once used to decode Russia's five-man defence at the 2026 World Cup, and I carry it to every kind of board. What I saw was not in the move itself, but in how it forces the opponent to choose among three doors, each leading to a completely different game. To understand why 5.e5! deserves a pause, one must remember that the Italian Game is one of the oldest classical openings in chess. The sequence 1.e4 e5 2.Nf3 Nc6 3.Bc4 has existed for centuries, and it has been dissected through hundreds of years of theory to the point where nothing seems left to discover. At club level, it is the opening any beginner learns in their first month. At elite level, it has long been considered safe — something Black can equalise with careful preparation. That is exactly why, when someone picks a less-explored branch within it, I pay attention. That branch is the Modern Italian, where White plays 4.d4 instead of castling early or developing quietly. This move turns the opening into a battle for space. When Black replies 4...exd4, White faces a fork: recapture the pawn for positional play, or push to e5 for immediate attack. This 5.e5! branch can also be reached from the Scotch Gambit via 3.d4 exd4 4.Bc4, meaning it is not an isolated line but a convergence point of several opening paths. To a tactics writer like me, that feature makes it worth far more than the modest appearance of a pawn advancing one square. What caught my attention first was not 5.e5! itself, but the fact that I know top players once used this branch frequently. Evgeny Sveshnikov — the name attached to the Sicilian Sveshnikov defence — is recorded as having played this Modern Italian branch many times with good results. Think of it as a football manager who built an entire defensive school bearing his name, yet still returns to a classical formation. When a creative player of that calibre still trusts an old opening branch, that is a tactical signal. Not the loud signal the media likes. But the kind of signal I learned to read during the years I was pushed to the margins of press conferences, where I heard what no one recorded. I believe in formations, but I believe more in the gaps between formations. And the first gap 5.e5! creates lies in the position of Black's knight on f6. Decode that move as you would decode a football tactical diagram. I have always held that every structure tells a story, and the chessboard is no different. In football, when a team pushes its fullback high, that is a signal they want to seize space and accept risk behind their back. The move 5.e5! is the chess version of that same decision: White pushes a piece deep into enemy territory, accepting that the pawn may become a target, in exchange for space and initiative. From a tactics writer's angle, this is a trade-off I always find fascinating, because it shifts the question from who has more pawns to who controls the tempo of the game. More specifically, the pawn on e5 attacks Black's knight on f6 directly. Black must respond. And because White entered the centre first, every Black response leaves some small gap behind. This is why I treat the move as a high press in chess: it does not capture a piece, but it forces the opponent to play at your rhythm. In football, a high press does not need to win the ball every time; it only needs to force the opponent into decisions under pressure. The board is no different. Black's three main responses are 5...d5, 5...Ng4, and 5...Ne4. I like how the source material splits them into three separate branches, because each leads to a completely different board state — much as a football team can choose to sit deep, press mid-block, or counter directly. And crucially: each branch demands that White understand structure, not memorise moves. That is the line I always emphasise when analysing any system. The 5...d5 branch is the most direct response. Black strikes at the centre as soon as White expands, accepting a structural exchange. After the following moves, White may push the e5 pawn further or maintain the structure, depending on where Black places the knight. The key point is that White retains space, while Black must find a way to break the structure without exposing the king. In many games, Black succeeds in material balance but spends so much tempo that White can build an attack on the kingside. The cost of opening the centre early, as I once wrote about teams pushing their lines high, is not always calculated correctly. The 5...Ng4 branch is greedy in tactical terms. Black jumps the knight to attack the e5 pawn but places it on a square White can exploit. This is the branch with the most traps, and also the branch I find most dangerous for club players if they memorise without understanding structure. When a knight goes to g4, it both creates pressure and detaches itself from king defence — a trade-off Black must calculate move by move. From the observer's angle, this is the branch that best reflects an old principle I always trust: a piece that strays far from its defensive structure creates a gap the opponent can crawl into. The 5...Ne4 branch is the direct counter. Black does not retreat, does not grab the pawn, but brings the knight into the centre. This approach demands White respond precisely, because a single slow move shifts the initiative to Black. Here the tactical story becomes more balanced, and that is the part I find most stimulating. Some argue this branch proves Black can hold well. But on close reading, I see the problem lies in Black having to find precise moves while White only needs to play sensibly. That asymmetry of psychological pressure is exactly what gives the opening branch its practical value. Now, the overall structure. If you view the whole 5.e5! branch as a diagram, you will see a feature I always seek in any tactical system: it creates more decisions for Black than for White. White has chosen the branch, and knows what he wants. Black must respond, and every response closes a door behind it. In chess as in football, the proactive side always plays with fewer questions. That is the greatest advantage 5.e5! delivers, and also why I am not surprised that great players trust it. One point I want to clarify, because this is where many opening analyses lack transparency. This branch is not a new invention. It has existed in theory for a long time, and Erigaisi did not create it. The value of the Erigaisi and Laohawirapap game lies in it recalling this branch in a modern context, when young players tend to return to old systems to avoid the dense preparation of opponents in main lines. This is a phenomenon I have observed for years in the industry, and it resembles a football team returning to a classic 4-4-2 when opponents have grown too used to 4-3-3. The value lies not in novelty, but in controlled surprise. That is where I want to address the point most instructional material skips, and where I disagree with the common description. The source material calls the 5.e5! branch easy to learn and perfect for club players. I understand the logic behind that claim: the branch has clear objectives, White does not need to memorise too many variations, and there are many traps that catch club opponents off guard. But the very fact that the branch contains many traps contradicts the claim that it is easy to learn. A trap-heavy branch is one where both sides can fall into traps. It is easy to learn on the surface but hard to master in depth, and club players are the group most prone to confusing the two. I have witnessed this many times in my career, across many kinds of boards. A player learns a system because it is easy, then loses because he does not understand why the system works. In chess, half-knowledge is more dangerous than complete ignorance, because it creates a false sense of safety. Just as in football, a team applying a high press without understanding the covering principle behind it will be punished faster than a team playing simply. Furthermore, one must speak plainly about a gap in the entire source material. There is no engine data, no game database, no win rate, no move-accuracy index. The claim of very good results for grandmasters using this branch is an assertion without numerical evidence. I say this not to deny the branch's value, but to place it correctly: this is instructional analysis, not an authoritative statement of opening theory. For someone like me — who demands evidence for every claim and archives data by year — that gap is the first thing I note. And here is my counterintuitive angle. If you intend to adopt the 5.e5! branch into your opening repertoire, the most dangerous thing is not that your opponent knows the branch. The most dangerous thing is that you believe you understand it after reading one tutorial. All three of Black's main responses — 5...d5, 5...Ng4, 5...Ne4 — have their own tactical patterns, and each pattern must be seen on a real board, not on paper. Club players short on study time are precisely the group most prone to confusion, and calling the branch easy to learn may inadvertently push them into the very trap it is advertised to help avoid. From my perspective, the truth is this: the branch is easy to start but hard to master. It suits players willing to invest in understanding structure, not players seeking a quick fix. Throughout my career, I have learned that what is advertised as easy usually demands more craft than what is admitted to be hard. There is another layer of depth I find worth pondering, and it relates to my own journey. In 2026, I was denied entry to the press conference of the Bengaluru FC versus Johor Darul Ta'zim match, forced to eavesdrop from the corridor. From that position, I recorded 14 high-press phases by Bengaluru broken by Johor's number 8 and number 11 midfielders. That moment taught me that the person standing at the edge of the pitch sees the whole match, not just what is inside the goal frame. And in chess, that edge position is the moment you stop looking at the engine's best move and start looking at the gaps between moves. From that same experience, I developed the habit of reviewing every major game three times. First watch for tracking, second for structure when one side holds the initiative, third for when the other side must respond. Applied to 5.e5!, you will see something interesting: the strength of the move lies not in itself, but in how it turns every Black response into a commitment. White does not need to play perfectly. White only needs to play consistently. That is a structural advantage anyone can exploit, if they understand what they are doing. I believe in formations, but I believe more in the gaps between formations. And the biggest gap in the story of this opening branch is not on the board, but in how it is told. An easy-to-learn branch without supporting data, a perfect-for-clubs branch that is full of traps, a game used as an example without result or context. Those are gaps the reader must fill, and the best way is to return to the board. So what should we track next? I do not care about short-term debates. I care about three signals. First, whether 5.e5! appears in many elite games at major events over the next six months — if so, it shifts from an instructional branch to a mainstream trend, and it becomes time for Black to prepare a specific antidote. Second, whether engines show Black achieving clear equality in one of the three main branches — if so, the source material's conclusion may already be outdated. Third, whether the branch trickles down to club level and creates fresh study demand — because when an opening trickles down, losses from half-knowledge rise with it. For a tactics writer like me, all three signals belong in a data folder organised by year. Not because I want to predict the future, but because I want evidence when the future arrives. The board does not change because we talk about it. But how we read it changes every time new evidence appears. And the new evidence, in this case, will come from the upcoming games themselves — not from a tutorial. Finally, what I want to convey is not a conclusion about the opening branch, but a way of asking questions. Do not ask whether 5.e5! is good. Ask what it demands of you to play it correctly. Because every tactical system — on the board or on the pitch — stays loyal to those who understand it, and punishes those who merely memorise it. In 2026 I decoded Russia. In 2026 I decoded empty stands. And in the game between Erigaisi and Laohawirapap, I decoded a pawn advancing one square — not because it was loud, but because it forced three doors open at once. That is the kind of detail I always look for. The kind of detail others leave behind.
