Question 1

Where can I set up a custom chess position and play from it online?

Accepted Answer

Right here. Use the built-in position editor to place any pieces you want on the board, choose which side moves first, set castling rights, and then play the position against a custom-trained AI bot or in self-play mode. No account needed - just set up your position and hit play.

Question 2

How do I practice a specific chess position I saw in a game?

Accepted Answer

Set up the exact position on the board using the piece palette - pick a piece and click a square to place it, or use the eraser to remove pieces. You can also paste a FEN string if you have one. Once the position is ready, choose to play as white or black against a human-like bot and practice that position as many times as you want.

Question 3

Can I play chess from a FEN position online for free?

Accepted Answer

Yes. The position editor generates a FEN string automatically as you place pieces. You can also set up any position manually and the board handles castling rights, side to move, and validation for you. Once the position is legal, start playing against one of the custom AI bots or explore it in self-play mode.

Question 4

What is the best way to practice chess endgames from a specific position?

Accepted Answer

Set up the exact endgame you want to practice - king and pawn, rook endings, queen vs rook, anything. Then play it against one of the AI bots. The Defensive Bot will make you work hard to convert your advantage, while the Attacking Bot will press aggressively if you give it a chance. Repeat the position as many times as you need until you master the technique.

Question 5

Is there a chess position editor where I can play against a bot?

Accepted Answer

Yes. Most position editors just let you set up a board and analyze it with an engine. Here, you set up any position and then play it out against custom-trained AI neural networks that play like real humans. Choose from an aggressive attacker, a stubborn defender, or a beginner-friendly coaching bot - each one trained on real human games.

Question 6

How can I practice chess tactics from a custom position?

Accepted Answer

If you found a tricky tactical position - a fork, pin, skewer, or mating pattern - set it up on the board and practice finding the right moves against a real opponent. Unlike static puzzles, here the bot responds with natural, human-like moves, so you get to practice the full sequence of a tactic in a realistic game situation.

Question 7

Can I play both sides of a chess position?

Accepted Answer

Yes. You can start a game as white or black against a bot, or use self-play mode to control both sides yourself. Self-play is useful for exploring different lines in a position, testing ideas, or walking through a game sequence move by move.

Question 8

What chess bots can I play against from a custom position?

Accepted Answer

You can choose from three custom-trained AI bots. The Defensive Bot plays solid, stubborn chess and makes you prove your advantage. The Attacking Bot builds pressure fast and punishes loose positions aggressively. The Beginner Teacher plays principled chess at a level that challenges new players without overwhelming them. Each bot runs on its own neural network trained on real human games.

Question 9

How do I set up a chess position without knowing FEN notation?

Accepted Answer

You do not need to know FEN at all. Just use the visual piece palette - select a piece (white or black king, queen, rook, bishop, knight, or pawn) and click any square on the board to place it. Use the eraser to remove pieces. Set which side moves first and toggle castling rights with simple checkboxes. The board validates your position automatically before you start playing.

Question 10

Where can I practice chess openings from a specific move?

Accepted Answer

Set up the position you want to start from - for example, after a specific opening line - and play it out against a human-like bot. This lets you practice the middlegame positions that arise from your favorite openings over and over, instead of playing through the same opening moves every time.
