5.e5! and the Erigaisi–Laohawirapap Game: When the Italian Game Returns as a Club Player's Weapon

Move five. The white pawn advances from e4 to e5. In the playing hall, almost nobody notices the moment — a pawn push that occupies one square, captures nothing, gives no check. But if you replay the Erigaisi–Laohawirapap game through an analysis engine, you see something entirely different: after 5.e5!, the black knight on f6 must choose between retreating, advancing, or trading. Each choice opens a different door, and behind every door there is a trap. An important note first, so the reader understands the spirit of this piece: everything analyzed below rests on a single source — an opening lecture within the "60 Minutes" series, published under the label "Game of the Week #740." That source provides no ratings, no game result, no engine reference lines, no database cross-check. The source itself marks its information points as "source: none." That means you are reading an analysis of instructional value, not a verified news report. I will make clear where material is fact and where it is inference. The Italian Game begins with 1.e4 e5 2.Nf3 Nc6 3.Bc4. It is one of the oldest systems in classical chess, refined by generations of players to the point of apparent exhaustion. The Modern variation discussed in the lecture runs 4.d4 exd4 5.e5!. The interesting part: the same position can be reached from the Scotch Gambit via 3.d4 exd4 4.Bc4. That is transposition — when two roads lead to the same room. For club players this is a gift: you need not study two systems, only one position and two or three ways into it. I spent 32 years commentating on chess for VTC, and probably as many years sitting at the analysis board. My tracking experience points to a rule: openings come back to life not because they are strongest, but because they are easiest to remember while hardest to punish. 5.e5! sits exactly at that intersection. It asks the opponent a question as early as move five, while the player using it only needs a few repeating tactical motifs. There is a historical name attached to this line: Evgeny Sveshnikov. The lecture notes that he and other grandmasters frequently used the Modern variation with 5.e5!, and asserts the line produced very good results for those who played it. I emphasize the word "asserts," because no statistics accompany it. This is a point I will return to in the contrarian section. What actually happens after 5.e5!? White gains central space and attacks the f6 knight directly — Black's most important defender on the kingside in the opening. Black cannot ignore it. The knight must move or be protected, and every option leaves a trace. The lecture lists three main replies: 5...d5, 5...Ng4, and 5...Ne4. I will go through each in the manner of a coach — focusing on the question the move asks, not merely the move itself. The 5...d5 branch is the most principled reply: Black strikes at the center, opens lines, and pressures the c4 bishop. It is the defender's move, refusing passivity. But precisely because Black strikes the center, weaknesses appear around the king. White often responds by increasing pressure on f7 or bringing the bishop to b5 to pin and force the knight to choose its fate. The key in this branch is not material gain but tempo. White spent one move pushing the pawn; Black must spend one replying; and in that gap White can develop faster. The 5...Ng4 branch is purely tactical: the knight leaves f6 while attacking the e5 pawn. It is the kind of move that rattles beginners. On the surface it solves the problem — the knight escapes attack and creates a counter-threat. But a knight on g4 sits far from the center, and in many lines becomes a second target once White stabilizes the e5 pawn. I always tell my students: when the opponent replies with a move that both runs and threatens, ask where that piece will be ten moves from now. The g4 knight often has no beautiful answer. The 5...Ne4 branch is opportunistic: the knight jumps into the center on e4 and challenges White to trade. A classic psychological trap lurks here. White may be tempted to simplify by trading, but trading actually helps Black free the position and escape pressure. Conversely, if White keeps the tension, the e4 knight becomes an isolated piece deep in enemy territory. This is where "easy to learn" separates from "easy to play." These three branches form the skeleton of the Modern line. Notice one thing: all three are reasonable moves, and all three lead to positions strategically different in nature. That is why the line is both attractive and dangerous. Attractive because it offers club players a weapon usable in any game. Dangerous because if you only memorize moves without understanding the question behind them, you will lose precisely the games you thought you had prepared. I want to be clear about the "many traps" claim. In chess, a trap is not a miracle. A trap is the consequence of forcing the opponent onto a narrow road. 5.e5! creates that narrow road by constricting Black's space from move five. But a trap only works when its setter understands why the road is narrow. Otherwise the trap bites the setter — the literal meaning of "eating one's own piece." One concept deserves mention here: engine match rate — the percentage of a player's moves matching the engine's top choice. In this context the lecture provides no such rate, nor any ACPL, the average centipawn loss measuring move accuracy. For an opening analysis, the absence of both is a large gap. You can accept the idea, but you cannot know how well it withstands machine scrutiny. This is where I must raise a serious doubt, which leads to the entire contrarian section ahead. The story of 5.e5! is told as a discovery, a revival of a forgotten chapter. But the data to prove that revival is missing. One game is not a trend. One lecture is not a database. And an unquantified claim of "very good results" remains a claim. There are forgotten moves, but data never forgets them. The problem here is that the data has not been produced. We have a beautiful idea inside an unverified frame. I once believed in emotion, until a number knocked on my door at 3 a.m. For this Modern line, that number has not yet knocked. And while it has not, the right thing is to record the idea and suspend it as a hypothesis awaiting verification. Now consider the line's value for club players. The lecture calls it a perfect choice for amateurs, relatively easy to learn. I think that is half true. The true half: the move sequence is short, the motifs repeat, few lengthy variations must be memorized. The other half: precisely because few variations must be memorized, players slip into overconfidence. They think they understand, when in fact they have only memorized. That is the line's biggest trap, and it is not on the board. It is in the player's head. Let me return to the Erigaisi–Laohawirapap game as teaching material. It was chosen as "Game of the Week #740," meaning it belongs to a very long numbered series. Such series usually serve education more than reporting. They do not narrate results; they point to a reusable idea. Here, that idea is 5.e5!. One regrettable fact: the source gives no result, no time control, no tournament. For a game used to teach an opening, the time control matters surprisingly much. In blitz and rapid, trap-rich lines like 5.e5! are far more lethal, since opponents lack time to find accurate defenses. In classical chess that lethality drops, because opponents can sit and calculate. Missing time-control information prevents a fair judgment of the example's persuasiveness. The same applies to the two players. If Erigaisi is Arjun Erigaisi — the Indian grandmaster — he is among the world's top players, and his choice of 5.e5! would carry signal value: the young elite are returning to sharp Italian systems to avoid the vast theory of main lines. If Laohawirapap is a lesser-known Thai player, the game is more illustrative than elite. I say "if" because the source confirms no identity, rating, or nationality. This inference should be treated as a hypothesis of medium confidence only. Another issue: the source provides no reference lines for 5...d5, 5...Ng4, 5...Ne4. So the conclusion that "Black struggles to equalize straightforwardly" is a reasoned opinion, not a proven evaluation. In modern chess, the gap between "reasoned" and "proven" is the gap between a good lecture and a tournament preparation file. There is a line I always use when teaching openings. The transfer market does not buy the past. It buys what the data has forgiven. Chess is the same. An opening does not revive because Sveshnikov once used it. It revives because modern engines find no clear refutation. If they find one, the line is forgiven in reverse — discarded. And this is my central contrarian point. The "relatively easy to learn" claim hides a technical truth. Trap-rich lines are the hardest to learn, only in a different way. They do not require memorizing thirty moves. They require understanding why an apparently harmless move can win. That is a far harder kind of understanding. Club players can memorize three main branches in one evening, but to play them correctly in a real game they need dozens of practice games. Between memorization and real play lies a danger zone. That is where players make the right move without knowing why, and are punished by an opponent who makes the wrong move but knows why. I have watched many such losses in amateur events. The trap-setter loses the trap. The shallow preparer is beaten by the deep preparer. Another warning concerns timeliness. The source does not assess time sensitivity, offers no current event context, and has no specific date. For an opening lecture that is not too serious. But for a sports news piece it removes an important layer: how often this line is played, by whom, and how frequently in the past six months. From that angle, I rate the competitive value of this content three stars out of five. Enough to bring into a club-level tournament hall. Not enough to overhaul your entire opening repertoire. And it carries almost no value at elite level, where everything must come with databases and engine evaluations. There is another nuance worth adding. In chess people speak of the revival of classical openings. Often there is no revival at all. There is rediscovery. A line that has existed for centuries is one day seen with different eyes. When 5.e5! appears in a modern game, it is not born. It is only remembered. If I had to compress the value of all this into one sentence, I would say: this is an invitation to learn a sharp Italian system, accompanied by a verification request the invitation has not yet fulfilled. So if you want to bring 5.e5! into your arsenal, here is the sequence I recommend, based on my own opening-preparation experience. First, open an engine and check the three main branches. Do not trust feeling. Trust the numbers. Second, classify the three branches by strategic nature, not move order. The 5...d5 branch is Black fighting for the center. The 5...Ng4 branch is tactical counterplay. The 5...Ne4 branch is opportunism. These three demand three different kinds of response and cannot be merged. Third, play at least ten games per branch against real opponents, not machines. Machines give you scores. People give you clock pressure. And in trap-rich lines, clock pressure is the decisive variable. Fourth, record your losses. Not to regret. To find the pattern in your own errors. If you only want to understand and follow, not play, then I suggest tracking a single signal: how often 5.e5! appears in elite games over the next six months. If it appears repeatedly at the 2700 level, the line becomes a trend. Black will then find an antidote, and the value of this lecture will be confirmed or refuted. Conversely, if six months pass with no such games, then what we are reading is a beautiful chapter forgotten once again. One line I save for the end. When the stadium is empty, the true value of a person begins to speak. In chess, when the stands fall silent and only the board and clock remain, the true value of a move begins to speak too. 5.e5! is such a move. It is not loud. It merely asks a question. That question, to this day, still lacks a data-confirmed answer. And that is why I keep this game in my mind, like a melody whose closing chord has not been found. For a club player, that is not bad at all. Sometimes the unverified chapters teach us the most about verifying ourselves. I light a candle for data. But I always let the flame of emotion illuminate the question. Because chess, after all, is a human game before it is a game of numbers. Remember this if you bring 5.e5! into a game next week: you are not playing a move. You are asking your opponent a question. And the best question is always the one whose answer the asker does not yet know — but is well prepared to handle every reply.
