A complete guide to using chess solvers and improving your move-finding ability.
Finding the best chess move is the fundamental challenge of chess. Whether you're a beginner trying to avoid blunders or an advanced player calculating deep tactical combinations, understanding how to evaluate positions and find strong moves is the key to improvement.
Modern chess solvers powered by engines like Stockfish can find the objectively best move in any position. But more importantly, learning from these tools helps you develop your own move-finding intuition.
Our Chess Tools
A chess solver is a tool that uses a chess engine to analyze any position and find the best move. The most popular chess solver engine is Stockfish, an open-source engine rated over 3500 ELO — far stronger than any human grandmaster.
When you use our chess solver, Stockfish evaluates millions of positions per second, looking 20+ moves ahead. It considers every legal move, calculates the consequences, and returns the objectively strongest continuation.
Modern chess solvers like Stockfish combine two technologies to find the best move:
The engine builds a tree of all possible moves. From the current position, it looks at every legal move, then every response, then every response to that — going 20+ moves deep. This brute-force calculation with clever pruning (skipping obviously bad lines) ensures nothing is missed.
At the end of each search line, the engine evaluates the position using its NNUE neural network. This trained neural network has learned to judge positions by analyzing hundreds of millions of examples. It considers piece activity, king safety, pawn structure, space, and thousands of other patterns.
The combination of deep search and accurate evaluation produces moves that are virtually perfect — no human can match a modern chess solver at full depth.
When you use a chess solver, you'll see evaluation scores. Here's what they mean:
A chess solver is most valuable when used for learning, not just copying moves. Here's the best approach:
After playing a game, load it into our game analyzer. The solver evaluates every move and identifies your mistakes. For each mistake, study what you played versus what the engine recommended — and try to understand why the engine's move is better.
When studying chess positions from books or videos, use the solver to verify your analysis. Set up the position, guess the best move yourself, then check with the engine. This builds your pattern recognition over time.
Check your favorite openings against the solver. If the engine gives a poor evaluation to a line you play often, it might be time to find a better alternative. Use the solver to understand critical moments in your opening repertoire.
While chess solvers give perfect answers, developing your own move-finding ability is the real goal. Here are proven techniques:
Before looking for your own moves, ask: "What is my opponent threatening?" Responding to threats prevents blunders — the #1 way beginners lose games.
Checks, captures, and threats are forcing moves — your opponent must respond to them. These are often the strongest moves because they limit your opponent's options. Grandmasters always consider forcing moves first.
When there are no tactics, find your least active piece and move it to a better square. A piece that's doing nothing is like playing with a handicap.
Chess puzzles train your pattern recognition. Spending 15 minutes daily on puzzles dramatically improves your ability to spot tactics in real games.
Combining your own analysis with chess solver verification is the fastest path to improvement. Play games, analyze with the solver, learn from mistakes, and repeat. Over time, you'll find yourself spotting the best moves without any help.

A chess solver is a tool powered by a chess engine (like Stockfish) that analyzes any position and calculates the objectively best move. It evaluates millions of positions per second to find the strongest continuation.
Stockfish uses alpha-beta search (looking ahead many moves) combined with NNUE neural network evaluation (assessing position quality). It calculates millions of positions per second, pruning bad lines and exploring promising ones deeply.
+1.0 means White is ahead by roughly one pawn. -2.5 means Black is ahead by about 2.5 pawns. +0.0 is roughly equal. Scores above +3.0 usually mean a winning advantage. 'M5' means checkmate in 5 moves.
Yes! Use it for post-game analysis to find your mistakes, not during live games. Reviewing where you went wrong and understanding why certain moves are better builds pattern recognition over time.
Yes. Using any engine assistance during rated online games or tournaments is cheating. Chess solvers are meant for learning, post-game analysis, puzzle solving, and training — never during competitive play.
At full depth, Stockfish plays at 3500+ ELO — far beyond any human. Its move suggestions are virtually perfect. The accuracy depends on analysis depth: deeper analysis = more accurate but slower.
Stockfish evaluates 1.e4 and 1.d4 as the strongest opening moves, both scoring around +0.3. 1.e4 is slightly preferred. 1.c4 (English) and 1.Nf3 (Reti) are also excellent. Avoid 1.f3, 1.g4, or 1.h3.
Yes, but strategically. Play your games without engine help, then use the solver afterward to review mistakes. This 'play then analyze' cycle is the fastest way to improve at chess.
