I thought I would share this personal anecdote just in case anyone was interested or curious.
This last January I competed in the Florida Class Championship and won my section. I happen to work with a lady who is a Master Hypnotist (she's now retired, and works for Disney part time, for fun mostly).
I was curious, so I asked her if she thought hypnosis could help my chess, as I really wanted to win my section. Her response was very interesting. She said:
*All hypnosis is self-hypnosis; some one may act as an aid, but you can only be hypnotized by yourself.
*It is not so much a TV-style trance state as it is a clearing of the mind and focus.
She paused, and then said "I don't know much about chess, but try this: instead of looking three moves ahead, only look two."
I took her advice, and concentrated on looking two moves ahead very accurately. The result was very interesting. I went 4.5/5 and tied for first, and in 3 of my 5 games, I won major material in less than 20 moves.
The funny thing was that, in each game, I won the material with two move combinations, but they weren't "obvious", in that I had to show my friends the combos, even though they weren't deep. Basically, I learned that people hang material all the time, and I wasn't looking hard enough.
As an aside, one of my friends remarked that I "played like Fritz", but I don't know if there is a connection there.
I'm curious to know if anyone else has any experience, or any thoughts at all positive or negative.
