I have the same experience with my level of play on chess.com - there are bad days when it feels like my hand is playing and some good days when I feel more like my head is playing. Not sure what external variable it is related to. In any case, you can play me if you befriend me there first ("Losna1", Losna - one, not Losna - capital i). I am 1400 on 10" time control, not much fun if you are more than 200 points far from that...
