Chess takes more than the mind to play
Nothing to loose! In my tough chess competitions I always remember my dad's advice "Just play chess". There is a time when you have literally no chance but motto "Never give up!" is spinning in your mind. My dad repeated several time play until last pawn, last soldier, last chance...
I was youngest in our chess team and have lost majority of the games in Kharkov (Ukraine) but our chess coach Odeev Ahmet give me a present a chess set signed "For willing to win!". This was remarkable gift from Ahmet and I played and analyzed game with the chess set many years. Thanks Ahmet for being my coach !
