5.e5! and Erigaisi's Teaching Game: When the Italian Game Returns to Club Players

I remember the night the analysis room lights were still on. After the fifth move of the game between Arjun Erigaisi and the Thai player Laohawirapap, the board settled into a position I had seen hundreds of times but only truly understood after sitting with it long enough. 5.e5! — a pawn push that looks unremarkable. But if you have played club chess for more than ten years, you recognize it at once: this is the move of a winner, not of a performer.

In the annals of chess, sometimes a single pawn push is enough to open an entire new chapter. This does not happen often. Opening theory is a slow current — major shifts require many years to take root in competitive practice before becoming standard. But when a variation thought to be dormant returns to the big board, it brings a question every club player must face: do they have enough patience to learn it properly?

That day I sat in the stands, never knowing I would step onto the field through words. I came to chess as a player, then an organizer, then a writer. Across more than thirty years, I learned one thing: the moves that look simplest often carry the most questions. 5.e5! belongs to that group.

The Italian Game — a classical opening and its twenty-first-century return

The Italian Game is one of the most classical openings in chess. It begins with three moves: 1.e4 e5 2.Nf3 Nc6 3.Bc4. In the nineteenth century it was the chief weapon of every attacking player, from Paul Morphy to the Italian romantics. In the twentieth century, as opening theory developed toward rigidity and precision, the Italian Game was pushed to the second tier. It came to be seen as a classical but insufficiently sharp opening for top-level play.

Then the twenty-first century arrived, and the Italian Game returned. Not through the romantic combinations of the nineteenth century, but through subtle transformations in pawn structure and piece deployment. Elite grandmasters — from Magnus Carlsen to Fabiano Caruana — began using the Italian not merely to avoid Spanish theory, but as a genuine attacking weapon.

The modern variation I want to discuss today follows the path: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4 5.e5!. This is the Modern variation of the Italian Game. It can also be reached from the Scotch Gambit via the move order 3.d4 exd4 4.Bc4. This transposition matters more than its appearance. If you are a club player already familiar with the Scotch, you can enter the same position without memorizing any new opening system. That is the practical advantage the source article emphasizes.

What happens on move five? After 4.d4, Black replies 4...exd4 — trading the central pawn. Instead of recovering the pawn with 5.Nxd4 (the main Scotch line), White plays 5.e5! — pushing the pawn to attack the Black knight on f6 while seizing central space. This is an asymmetric act. White is not trying to balance material. White is trying to seize space and tempo.

This move was once controversial in chess magazines of the 1980s and 1990s. Some analysts argued it was too greedy — White pushes a pawn to e5 without enough piece support, opening strong counterplay for Black. Others, including Evgeny Sveshnikov, argued it was a deeply strategic weapon that had been undervalued. According to the source article, Sveshnikov and several other grandmasters used this line frequently and achieved very good results.

I should be direct: I do not have a database to verify that claim of very good results. It is recorded opinion, not verified statistics. I am not saying it is wrong. I am saying that if you intend to use this variation as a weapon, you must verify it yourself with an engine and a database before adding it to your arsenal.

Black's three replies — three strategic philosophies

After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4 5.e5!, Black has three main replies covered by the source article: 5...d5, 5...Ng4, and 5...Ne4. These are three different philosophies for dealing with an attacking pawn push. Each line opens its own training garden, and club players need to understand the ideas before memorizing the moves.

Line one — 5...d5: central counterplay through structure.

This is the most classical reply, and the one many Black players choose by instinct. Black pushes the d-pawn from d7 to d5, trading to open the d-file and create space for the pieces. In principle, Black is trying to re-establish central balance after allowing White to occupy space with 5.e5!.

But there is a paradox in this line. After Black has already given up the central pawn on 4...exd4, playing 5...d5 means Black admits a new pawn must compensate. White, meanwhile, already holds a spatial advantage on e5. If White plays accurately, White can pressure the d5-pawn and the f6-knight simultaneously — two targets in the same area. That is a basic principle of chess tactics: two targets attacked at once are stronger than two attacked separately.

The most important thing in the 5...d5 line is tempo. White does not need to score material immediately. White needs to sustain pressure and force Black to choose among several equally uncomfortable defensive options. In modern chess, sustained pressure is far harder to handle than a combination that can be calculated a few moves ahead. That is why this line troubles club players facing well-prepared opponents.

Line two — 5...Ng4: the audacious reply.

The move 5...Ng4 sends the Black knight diagonally from f6 to g4, stepping out of the e5-pawn's attack while applying pressure to weak squares around the White king. Black is betting that keeping a piece active matters more than keeping a tidy pawn structure.

This is also the most punishable line if Black is not well prepared. A knight on g4 sits on the rim of the board, vulnerable to moves like h3 or other White pawn advances. If White can force Black to trade the knight on g4 under unfavorable conditions, White gains a clear spatial advantage and a healthier pawn structure.

But if White mishandles it, the g4-knight can become a sharp attacking spearhead. In many club games I have seen White players surprised by variations arising from g4 — variations not written in books. That is why I recommend: if you play 5.e5! as White, study the 5...Ng4 line before any other. It is the line your club opponent is most likely to choose when they want to improvise.

Line three — 5...Ne4: the pragmatic reply.

The move 5...Ne4 brings the Black knight into the center, attacking the d2-pawn and controlling important squares. Black plays by the classical principle: when pressured, occupy the center before retreating. This is the most professional reply of the three, and the one experienced players choose.

The paradox here is that when the Black knight stands on e4, it is both spear and shield. It attacks, but it also blocks some White pieces. If White trades accurately — usually by preparing supporting moves first — Black loses its most active piece and falls into passivity. Conversely, if White hesitates, the e4-knight can become a fulcrum for a large counterattack.

In all three lines, one principle is common: White does not need to win tactically. White needs to win on tempo. This matters more than any specific move. Because at club level, most games are decided by who sustains their tempo longer — not by who memorizes more moves.

Tactical motifs — patterns to understand, not to memorize

Any variation described as trap-rich shares a common feature: it contains traps for both sides. This is what club players often misunderstand. They think trap-rich means a line I will win if my opponent does not know it. But reality operates the other way: if you play a trap-rich line without understanding it, you are the one most likely to fall into traps. Because you are entering terrain you do not fully know.

In the 5.e5! line, one of the most common tactical motifs is Black trading the knight on f6. When the Black knight leaves f6 and the White pawn advances to e5, the pawn structures of both sides change. White can open the e-file for the pieces, but Black can also open the f- or g-file. The battle does not take place on the physical board. It takes place in the minds of the two players, each trying to predict the other's tempo.

Another motif I often see in club games: White pushes the pawn to e5, Black replies 5...d5, White plays Bb5 to pin the c6-knight, and Black must choose between trading pieces or continuing development. If Black chooses wrong, Black's pawn structure becomes unbalanced and White can attack the center with advantage.

But here is the point I want to stress: these motifs are not formulas. They are patterns to be understood, not memorized. If you learn them as formulas, you will win some games and lose others without understanding why. If you learn them as patterns, you can adapt to any reply your opponent makes.

Evgeny Sveshnikov and the story of undervalued lines

Evgeny Sveshnikov (2026–2026) was a bridge between Soviet theory and modern chess. He is famous for the Sicilian Sveshnikov — a line he developed over decades and that is still played at the highest level today. But Sveshnikov was also a man eager to explore lines few others played. If he truly used 5.e5! as a long-term weapon, that is a signal the line has more strategic depth than its surface suggests.

According to the source article, not only Sveshnikov but several other grandmasters used this line. But the source article provides no specific names, no specific game counts, no specific win rates. That is what you must note when reading. In chess, claims that many grandmasters have played something can be true anecdotally but cannot serve as a basis for judging a line's strength.

What I can do is look at the strategic logic. If a line has been used by many grandmasters across different decades, it usually has a core strength independent of era. With 5.e5!, the core strength is this: it forces Black to choose first. White asks the question, Black must answer. In chess, forcing the opponent to choose first often brings psychological and time advantages.

My experience of watching — from the stands to the analysis board

In over thirty years of watching chess, I have seen many undervalued opening lines become formidable weapons after a prominent player added them to their arsenal. In 2026, while covering the Women's World Cup in Le Havre, I learned a lesson I apply in chess as well: the true value of a moment is not in its statistics. It is in its capacity to open a new angle for those watching.

With 5.e5!, I see something similar. The Erigaisi vs Laohawirapap game carries no significance in the FIDE rating list or any qualification path. But it has educational significance: it shows a classical line still has vitality when placed in the hands of a young, bold player. And in the chess world, a line's vitality — not its player count — is the indicator of its future.

When the cheers fell silent, I finally heard the true breathing of the game. I wrote that line in a piece about the 2026 shutdown, and it still holds in chess. In a game with spectators, moves are obscured by crowd emotion. But when you sit alone analyzing with the board, you see what actually happened. 5.e5! is a move that appears most beautiful when analyzed alone.

The empty corridor of 2026 taught me that the field never dies, it only waits. In chess, opening lines are the same. Some lines are forgotten for years, then return in a small game at some open tournament, then spread through databases, then become standard. 5.e5! shows signs of a line waiting for its moment.

The question of the easy-to-learn claim — a counterintuitive angle

This is where I must say what I believe but not everyone wants to hear: the easy-to-learn claim attached to any opening line is the most suspect claim in chess analysis. No opening line is truly easy to learn. Some lines are easier to remember, but none is easier to understand once an opponent deviates from the book.

The source article says 5.e5! is perfect for club players because it is relatively easy to learn and trap-rich. I understand the logic. White has a clear plan: push the pawn, seize space, attack. But I want to point out three problems that claim overlooks.

The first problem is time pressure. At club level, you have no team of assistants or engine to help during the game. If you study the line for twenty hours and your opponent studies it for five — but your opponent understands the strategic ideas better — you can lose despite superior memorization. Easy to learn never accompanies easy to understand.

The second problem is two-way traps. The trap you think you are setting for your opponent may be the trap you are walking into. In the 5.e5! line, if you attack too fast without maintaining your pawn structure, you can be counterattacked on the very file you opened. This has happened to many club players without being recorded in any database.

The third problem is engine verification. Without engine evaluation, without database data, the claim that Black struggles to equalize is a reasoned opinion, not a proven fact. I am not saying it is wrong. I am saying it needs verification before you add it to your arsenal.

Tactics resemble people: you must know who you are before you try to become someone else. And in chess, knowing who you are means knowing how deeply you understand a line — not how well you have memorized it.

Of course, I do not deny the value of 5.e5!. I only want to place it in correct context. This line is stronger than many others at club level — but strong for strategic reasons, not theoretical ones. That is an important distinction. Because theoretical reasons can change when engines update. Strategic reasons endure longer.

How to study this line in practice — a suggested process

If you are a club player and want to add 5.e5! to your arsenal for the annual season, here is the process I suggest based on my experience watching and analyzing.

First, install the line into a personal database. Do not rely on memory. Human memory is unreliable in an opening as branching as this one. You need a notes file you can access quickly during post-game analysis.

Next, play the line against an engine in self-play mode, taking both sides. You need to see how the engine handles the 5...d5, 5...Ng4, and 5...Ne4 lines. Do not only look at White's best move. Look at Black's best move — because those are the moves you will meet in real games.

After that, play the line yourself from both sides in at least twenty rapid games. This is the only way to move from theoretical understanding to intuition. When you have played enough, you will begin to see the right moves without thinking. That is when an opening line truly becomes yours.

Finally, play the line in at least one real tournament before trusting it fully. Tournament pressure differs from analysis pressure. What you understand in the analysis room can vanish at a board with a clock running. Only a real tournament can tell you whether 5.e5! suits you.

A progressive conclusion — the question left behind

In chess there are two kinds of players. The first studies lines to win a particular game. The second studies lines to understand a truth about the board. The first wins more games in the short term, but the second improves faster over the long term. Both deserve respect — but only the second truly matures in this intellectual sport.

5.e5! belongs to the group of lines meant for players of the second kind — those willing to spend time understanding why a pawn push on move five can matter so much. Because what this line teaches — tempo, space, sustained pressure — applies not only to the Italian Game. It applies to every opening, every system, every game. Once you understand tempo in this line, you will see it everywhere: in the Sicilian, in the French Defense, in every game you play.

Signing a contract is black and white on paper, but staying is a matter of the heart. With openings, the same is true. Memorizing a line is black and white on paper. Understanding it deeply enough to create within it — that is a matter of the heart.

So the question I leave for you, Vietnamese chess players seeking new weapons for the annual season: are you learning 5.e5! to win a game, or to understand a truth? The answer will decide whether this line remains in your arsenal a year from now — or only until your first win. And if the answer is truth, then this line never grows old. It merely waits for the next generation to learn it again, in their own way.
