Computer Moves for me automatically, and moves wrong!

https://lichess.org/zuU1fL50/white#16 On the very next move #17, the correct move is QxH8, but the computer, without my input, move QxG6, a fatally inferior move. This happens to me about once a week, where the computer moves my piece in response to a capture. Sometimes, many times, it makes a rationale re-take, but obviously in this case it did not.

So you're saying you're just sitting there looking and all of the sudden this move appears on your screen?

So you've got your computer to make moves for you? You're cheating with a bad engine?

You made a premove. You can turn it off if you want. https://lichess.org/account/preferences/game-behavior
