Guilty Secrets

Have you got a guilty secret that you would love to share but probity, manners, or the local homicide laws prevent you from revealing to a soul?
 
Mine is simple and very satisfying.  I last used it in Tournament play in the Chess Monstathon by Brynmawr market.
 
Before each OTB match I like to take a big swig of fresh pig’s blood and just hold it in my mouth during the game. 
 
My opponent doesn’t suspect a thing.
 
I roll it around my mouth as it gradually cools to aid my concentration. 
 
It helps to calm me and keep me from a state of flummoxation under pressure.
 
When I win, which I usually do, I just look my opponent in the eye and swallow.  The sweet taste of success.
 
But that’s not the best bit of my delicious secret.
 
If I am in a hopelessly lost position (rare).  Just before the final mating attack I feign a huge sneeze and explode a bloody tsunami covering my opponent, the board and all of the pieces in a thick slick of what appears to be my own blood.
 
The game is usually declared a draw whilst I am whisked away in an ambulance for urgent medical attention.
 
I am usually discharged within the hour to go back and pick up my trophy.

Genius.

What are your guilty secrets?

lol genius 

I team up with a few parapsychologists : one behind my opponent, other to my right side, a third two blocks from the club house facing West and a forth near the favorite opponent´s female.

Funny, people spontaneously squirting blood in chess matches is rather close to my secret. I cannot say more.

Unfortunately you can only use it once per tournament otherwise people suspect.
