How fast do beginners get checkmated? 4.5 million games, counted

Lichess publishes every rated game played on the site. We read the start of the September 2026 file: 4,537,081 rated games at bullet, blitz, rapid and classical speeds. For each one we noted how it ended and on which move. A game counts as an early checkmate if it ended in mate on or before move 15. Each game is placed by the average rating of its two players, so a 900 against a 1100 is a game between players rated 1000.

These are Lichess ratings, which run higher than chess.com's. If you play on chess.com, read the bands about 200 points lower than your own number would suggest.

Under 1000, 1 game in 17 is over by checkmate before move 15. By 1400 to 1600 it is 1 in 53, and at 2000 and up, 1 in 150. No band breaks the pattern: every 200 points of rating makes an early mate rarer.

Slower games are not safer. Under 1000, an early mate ends 1 rapid game in 13 but 1 blitz game in 19. Part of the reason is that beginners play on to the end: 41% of rapid games under 1000 finish in checkmate of any kind, against 17% at 2000 and up, where a lost position is usually resigned.

Count the early mates under 1000 by the move they came on and one stands out. Move 4 has 1,186, far more than move 5 with 699, and no later move passes it until move 11. There is one reason for that spike, and every chess coach has seen it.

Counting every move order of it, Scholar's Mate ends 1 game in 550 under 1000. At 2000 and up it ends 1 in 51,700: nearly a hundred times rarer. It is a trap that works on people who have never seen it, and almost everybody sees it eventually.

Not every trap is a beginner's trap. Some need the victim to know just enough to take the bait.

Between players under 1200, White gives mate by move 15 in 1 game in 33 across all openings, and Black in 1 in 54. Some openings sit far from those averages, in both directions.

1.e4 e5 2.Qh5 and the Bishop's Opening both end with White mating by move 15 in 1 game in 12, nearly three times the usual rate. In the Two Knights Defence it is Black who is mated quickly, in 1 game in 19. At the other end, the London System is the quietest way to start a game as White: White is mated that fast in only 1 game in 130.

We have marked the openings where an early mate is at least one and a half times as likely as usual, for either side, as essential for beginners. They are the ones to learn first, whether you want to play them or just survive them.

If you are under 1000, most of your early losses come from the same few patterns, and the commonest go through f7 or f2, the pawn only the king defends. Before every move, look at what the opponent's queen and bishops are aiming at. Learn the defence to 2.Qh5 and 2.Bc4: …Nc6, …g6, …Nf6, in that order. It takes ten minutes, and it takes Scholar's Mate off the board for good.

How this was counted: the first 1.5 GB of the Lichess database file for September 2026, every rated standard game in it with both ratings, nothing filtered out by result. A game is an early mate if its last move gave checkmate on move 15 or sooner. Whole games are only recorded when they ended in mate within ten moves and happened at least 20 times.
