How the Decoder Works
Enter the moves
Paste the opening moves from your game. You do not need the full game. Six to twelve moves is usually enough to identify a trap.
Get the match
The decoder normalizes your input and checks it against every known trap line. If a match is found you get the trap name, the correct move order, and the refutation for the side that got trapped.
Learn the pattern
Each result includes a short pattern tip. These tips help you spot the setup before the trap fires, even when the move order shifts slightly.
Why club players keep losing to the same traps
Most intermediate players know the names of common traps but forget the exact refutation under time pressure. You might remember that Scholar's Mate is bad but still play the wrong reply on move four. This decoder gives you the exact move in seconds so you can check it between games. The pattern tips are the real value. Once you understand the tactical idea behind a trap, you start to see it coming in different openings. The Fried Liver, for example, relies on a knight sacrifice on f7 to expose the king. That same idea shows up in the Two Knights Defense and even in some lines of the Vienna Game. Learning the pattern once saves you from losing to it five different ways.
The hit log keeps track of every trap you have fallen into. Over time you will see which traps catch you most often. Focus your study on those first. A player who keeps losing to back-rank mates should spend ten minutes on rook endgames before drilling pawn structures.

Common Mistakes When Studying Traps
- Memorizing moves without the idea. You will forget them in a week. Focus on why the trap works. What piece is overloaded? What square is weak?
- Only studying your own games. Review master games that use the trap. See how strong players set it up and how defenders avoid it.
- Ignoring transpositions. The same trap can arrive from different move orders. Learn the key position, not just the move sequence.
- Playing the trap yourself without knowing the refutation. If you try to spring a trap and your opponent knows the refutation, you are the one who loses.
- Not reviewing your hit log. The log is useless if you never look at it. Spend five minutes before each study session reviewing your recent hits.
