My easy method to avoid mouse slips.

It's easiest to explain this with a diagram.

Say that you are playing the White pieces here and want to capture the Black Rook on e8, instead of clicking on the Queen and dragging it in a straight line towards the Rook, simply drag it in a curved path (as shown on the diagram). This way, if you accidentally let go of the Queen, it is much more likely that it will be judged as an illegal move, and the Queen will be put back to where it was so that you can try again. Voila, no more frustrating mouse slips that lead to losses!

This method works for other pieces too. Of course, it is best used in longer games when you have more time, as you don't care as much about moving the pieces further and costing valuable seconds.

Thanks. I had no idea that you could do that. I guess I'm just so used to dragging the pieces.
