3 Practising protecting pieces

Move directly on the board to input a solution. Either click first on the start square and then on the target square. Or click on the piece, hold on to it, move it tot he target square and let go of it. The button ‘Left arrow’ takes back the move.
Start again
Firstly, after every move of your opponent check whether one of your pieces is being attacked. Decide whether you will protect the piece under attack or move it away.
