5.e5! – When Classical Theory Becomes a Weapon: Decoding Italian Game Modern Through the Erigaisi Game

The first thing I did after reviewing the Erigaisi – Laohawirapap game was to open my old Excel sheet. I created that spreadsheet in 2026, on an evening in Nizhny Novgorod, after discovering that France's midfield re-pressed just 5.2 seconds after losing the ball, compared to the tournament average of 7.8 seconds. Chess is not measured in seconds. It is measured in moves. But the principle is identical: a small decision on move five can shape the structure of the entire game behind it. The move 5.e5!. Seen for the first time, it looks simple. It looks like a hasty pawn push by a young player eager to attack, eager to raise everything, eager to create pressure before the opponent can breathe. But if you sit down at the board, reopen the game, and log every Black option, you will find this is not a hasty pawn push. This is a system. Built over decades by names like Evgeny Sveshnikov, and now returning to the elite board through Erigaisi's hands. That is why I am writing this piece. Not to teach you an opening move. But to show you what happens when classical theory is re-read with fresh eyes – and what happens when we confuse "having learned" an opening with "understanding" it. To understand 5.e5!, you have to understand where it was born. The Italian Game – 1.e4 e5 2.Nf3 Nc6 3.Bc4 – is one of the oldest openings in chess history. It appeared in the 16th century in Italian manuscripts, and for much of the 20th century it was considered "out of ideas" as elite theory shifted toward the Sicilian, the Ruy Lopez, and other closed, harder, more complex systems. There is a small point I want you to notice before we go into technical detail. The "Modern" variation of the Italian Game with 4.d4 is not a 21st-century invention. It has existed for a long time. But this time, it arrives from a different road: the Scotch Gambit. If you play 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4, you are in the Scotch Gambit, and the opponent can transpose into the same position with 4...Nf6. Chess is like that – one position, two roads, and sometimes people arrive by a road others never thought of. Why does this matter? Because it says something about modern elite opening play: the value of unpredictability. When every 2700+ player has already prepared twenty-five moves of the Najdorf and the Berlin, a game can be decided not by who understands chess better, but by whether your opponent has ever seen this position in his preparation file. The Italian Game Modern is one of those lands few walk through. Not because it is weak. But because it is so classical that people forget it is still there, still waiting, still capable of being used as a weapon. Evgeny Sveshnikov understood this earlier than most. Throughout his career, he was not only famous for the Sicilian Defence that bears his name. He was also one of the most frequent users of the Italian Game Modern at the highest level. When a Grandmaster chooses an "old" opening and persists with it across decades, that is not conservatism. It is a declaration: I believe in this position more than I believe in trends. And chess history shows that such declarations are often right. And here is what I want to add about history. This opening is not a new phenomenon. What Erigaisi did was simply to play it at a moment when everyone had forgotten it. In chess, sometimes the greatest value of an opening lies not in how strong it objectively is, but in how well your opponent knows it. This is a principle elite players grasp better than anyone: surprise has its own value, and the greatest surprise sometimes comes from the most familiar things. Erigaisi, far younger, probably did not think much about history when he chose this move. But his game against Laohawirapap is a reminder that theory does not die. It only waits to be re-read. Now let us go into the game. And I will not narrate every move in chronicle style. I will do what I always do when I analyse: open the board, set a symbolic stopwatch, and measure. After 5.e5!, Black has three main replies. Not three out of countless. Three. Because other moves either give White a clear space advantage with no compensation, or lead to positions where White fully controls the tempo of the game – one of the most basic principles of opening play. Option one: 5...d5 This is the most "by-the-book" answer. Black counterattacks the centre just after White has pushed the pawn to e5, attacking the f6-knight. Black's idea is very natural and very logical: if White pushes the pawn to e5 to attack, then Black will open the centre to punish that greed. This is the way any player learns to play chess from the earliest days: attack the centre when the opponent overextends. But here is the key point I want you to remember. After 5...d5, White does not need to defend the e5-pawn at all costs. White plays 6.Bb5!, pinning the c6-knight, and more importantly, attacking the very f6-knight that the e5-pawn is targeting. The position becomes a race between the two sides to determine who controls the central squares, and who develops faster. Black has a d5-pawn in the centre, but that pawn lies in the sights of White's undeveloped c3-knight, and White's e5-pawn controls f6 – where Black's knight has just left or will have to leave. This is where you have to sit down at the board, because nothing more you read can replace doing the calculation yourself. I will tell you this from the experience of someone who has logged thousands of games across many events: the difference between a 2200 player and a 2700 player in this position is not in knowing the right move. Both know the right move when they see it. The difference lies in understanding why that move is right – so that when the opponent deviates from theory by one move, one still knows what to do. 5...d5 is not a trap in the ordinary sense. It is a psychological trap: it makes Black believe he is counterattacking, while in reality White is directing the story. And once Black believes he is attacking, Black will play attacking moves – when what the position actually demands is defensive precision. This is the most subtle trap in chess: not the one that makes you lose material immediately, but the one that makes you believe a false story about your own position. Option two: 5...Ng4 Here everything becomes harder. Black does not counterattack the centre. Black attacks the e5-pawn directly. The knight jumps from f6 to g4, aiming straight at the e5-pawn, forcing White to make a decision immediately – with no time to develop calmly. This is where players new to the opening usually make their first mistake. They defend the e5-pawn with 6.h3 or 6.Bf4 or 6.Nc3, and they keep the pawn structure – but they give Black time to develop, and more importantly, they lose the attacking momentum that 5.e5! created. In chess, a pawn on e5 is not just a pawn. It is a blade pointed at f6, and if you withdraw that blade to protect it, you have lost its reason to exist. The sharper idea is to understand that the e5-pawn sometimes does not need defending in the ordinary way. It needs to be used as bait to pull Black's pieces onto squares where they will be exploited ten moves later. If Black greedily takes the pawn, White can open diagonals and files with tactical blows that ordinary players do not see before move thirty. This is what I want you to engrave: in the Italian Game Modern, the value of the e5-pawn does not lie in the pawn itself. Its value is the tension it creates – a tension Black must resolve, while White is already prepared with an answer to every possible resolution. That is the principle of every good attacking opening. You do not attack to win material. You attack to create uncertainty, and to control how the opponent resolves that uncertainty. I have reviewed the Erigaisi game many times. What caught my attention was not any specific move, but the tempo. Erigaisi was not hurried. He did not attack crudely. He placed tension on the opponent, then waited – waited for Black to choose a direction, and then exploited the asymmetry that choice created. That is how a player who truly understands the position plays. Not attacking. Sowing tension. Option three: 5...Ne4 This is the most counterintuitive option, and also the one I believe many club players do not prepare thoroughly enough. Black brings the f6-knight to e4 instead of g4. At first glance, a knight on e4 looks powerful – it sits in the centre, it attacks c3 and d2, it is an ideal outpost. But it is also a target. It is attacked by... which move? And this is where you realise that 5.e5! does not merely attack the f6-knight. It creates a network of attacks that Black must pass through node by node, and every node costs something. What happens if Black plays 5...Ne4? White can play 6.Bd5 or 6.Qe2 or subtler moves depending on the specific structure, and in every case Black must calculate continuously with high precision. One wrong move, and the knight on e4 is trapped, or Black's pawn structure collapses, or White gains a strong centre with tempo. This is why I emphasise 5...Ne4: it is the typical "all or nothing" option in elite openings. There is no peaceful draw here. Black either finds a very narrow path to equality – a path even 2700 players must calculate carefully – or is strategically crushed. And in practice, at club level, the rate of "being crushed" is far higher than the rate of "finding the path". This is what I want to say overall. When an opening produces three main options and each demands high precision from Black, then it is not an "easy" opening. It is a hard opening – but the difficulty lies on Black's side, and that is the entire idea behind 5.e5!. Before moving to the rebuttal section, I want to add one aspect that most analyses overlook: the psychological factor in the tournament hall. I have sat in many commentary rooms, watching many players in tense situations. When Black meets an opening he knows is dangerous but does not remember precisely, he will play slower, more hesitantly, and be more prone to calculation errors. 5.e5! does not only attack on the board. It attacks the opponent's clock. And in modern chess, where both sides have supporting tools and thorough preparation, time is the real strategic weapon. Everything on the board is data waiting to be read – if you are willing to sit down. The original article said the Italian Game Modern is "perfect for club players" because it is "relatively easy to learn" and "contains many traps". I understand the logic behind that claim. But I do not agree with it – not because it is wrong, but because it is insufficient, and in chess insufficiency is often more dangerous than being wrong. An opening that is "easy to learn" is one you can learn the first five moves of in one evening. An opening that is "easy to understand" is one you understand in... how long? A year? Ten years? I have tracked and logged thousands of games over more than forty years, and I still learn something new about positions I thought I understood. Chess knowledge is not a pond you drink dry. It is a deep well, and each time you lower the rope, you pull up a new bucket. The real danger of a "trap-heavy" opening is that it creates an illusion of strength. You learn five moves, you win three games at a club tournament against opponents playing classical theory, and you believe you have mastered the opening. Then you meet a well-prepared opponent who plays precisely, and you do not know why you are in a worse position after fifteen moves. You have nothing to blame, because you never truly understood the position. You only remembered it. This is the core distinction I want to stress: between remembering an opening and understanding an opening. Memory can be broken by an unexpected move. Understanding can adapt. If you want to learn the Italian Game Modern, learn it as a dialogue with the board, not a list of moves. Learn all the main options – 5...d5, 5...Ng4, 5...Ne4 – and ask yourself why each leads to its own strategic consequence. Learn the typical positions ten moves after the opening ends. And accept that you will lose many games before you win one with genuine understanding. There is no shortcut in chess. Only shortcuts salesmen trying to convince you there is. I no longer believe in miracles on the board; I only believe in the silent hours spent sitting before a position. The Erigaisi – Laohawirapap game will be forgotten in a few months. Games come and go, and the chess community's memory is shorter than we think. But the question it poses will not be forgotten: do we play chess with memory or with understanding? The answer lies in no opening. It lies in no book, no course. It lies in the number of hours you sit quietly before the board, reopening each option, re-measuring each line, and asking yourself what you are really seeing. Chess does not reward the one who remembers most. It rewards the one who understands deepest. 5.e5! is a move. But it is also a question you must answer yourself.
