Gambitly

Gambitly is a chess opening trainer built on what players really do. It measures traps, mistakes and openings on 86 million rated games from a single month, then lets you practise them at your own rating. It is for club players and improvers who keep losing the same way in the first ten moves.

Why trap lists can mislead

Opening books often list famous traps, but they rarely say how often anyone falls for them. A trap that wins in a textbook may almost never work against real opponents at your level, and a quiet mistake may cost many players points every day. Gambitly ranks 22 classic traps by how often players really fall for them, including the Fried Liver Attack, Scholar’s Mate, Fool’s Mate, the Englund Gambit, the Stafford Gambit, the Vienna Gambit, the Blackburne Shilling and Légal’s Mate. You can see the fall rate in four rating bands.

Learning a trap properly

Replay every trap move by move, with sound. Then switch roles and set the trap yourself: you play, and the opponent falls in. Each trap has a short “why”, explaining why the move is a mistake and how it is punished. Knowing the punishment matters as much as knowing the trap, because opponents do not always walk into it the way the book says.

Common mistakes from real games

The app lists 68 opening mistakes found from engine scores in real games, ranked by how many players make them. Each one is a puzzle. Your opponent has just gone wrong, and you have to find the move that punishes it. This is good practice for a common situation: noticing that the other side has slipped.

Studying any named opening

Gambitly includes 1,784 openings and variations, from the Sicilian and the Caro-Kann to the London System. For each, you see win, draw and loss rates by rating and by time control: bullet, blitz, rapid and classical. Explore move by move to see how often each reply is played and how it scores at your level. This helps you choose a line that suits how you actually play, rather than one that looks good only at the top.

Practising against realistic replies

In practice games, your opponent answers with the moves players at your rating actually play, as often as they play them. Every move you make is scored against what players at your level achieve with it. Over time you learn the replies you are likely to meet, not just the main line.
