The Chess Camel-Queen

Today few people from our chess club had a meeting in a cafe and played a swiss blitz tournament. I have played very few blitz games, actually I have just started. I won only one game because my opponent had no more time left, but I also had only 1 second left! In another game I lost although I had one more rook due to time again. And in the last one I did such a horrible mistake. Lost in calculating some movements sequences I placed my queen in the range of the enemy's knight. I did not see it!

Loosing a queen this way, is as if I am looking at a camel and I am unable to tell whether she is a camel or a dog. Or a desert's optical illusion. She is not even there!

Frustrating.
