Free pieces: teaching children to ask "Who's watching?"

10 November 2026 · 2 min read · The ChessMons team

In the first months of chess, most games are not decided by clever plans. They are decided by pieces left where they can be taken for free. A knight wanders forward, nobody guards it, and a moment later it is gone. The good news is that one small habit fixes most of this, and children as young as three can start practising it.

Two questions before every move

Teach your child to ask two questions, out loud at first:

  • Who's watching my piece? Before moving, look at the square the piece is going to. Can any of the other side's pieces capture it there?
  • Who's guarding it? If the piece can be taken, is one of my own pieces ready to take back?

If a piece can be taken and nobody guards it, it is a free piece for the other side. That move needs a second think.

Tip: make it a game. Before your child lets go of a piece, say "Who's watching?" together, and point at every enemy piece that could reach the square.

Turning it around: spotting free pieces

The same two questions work in the other direction. After the other side moves, ask: is any of their pieces standing where I can take it, with nobody guarding it? Children love finding a "free snack", and it trains them to look at the whole board instead of only at their own pieces.

Start simple. Set up a board with just a few pieces, leave one of yours unguarded, and ask your child to find it. Then swap roles and let them set the puzzle for you.

Keep it light

Young children will still leave pieces hanging, and that is completely normal. The goal is not perfect play but a growing habit of looking before moving. Praise the looking, not just the result: "You checked who was watching. Great thinking!"

How ChessMons helps

In ChessMons, Professor Tock watches for exactly this moment. When a piece moves to a square where it can really be lost, the square turns red and every piece that could take it gets a pair of eyes. Your child can see who is watching, think again and choose a safer square. Takebacks are always allowed, so a mistake becomes a small lesson rather than a lost game.

In the How to Play lessons and Practice, the early puzzles are all about taking free pieces and keeping your own safe, so the habit grows a little every day.
