Answers.Body: <p>Since you answered my comment that you don't drink water, sodas or eat snacks during games, maybe you should give these a try.</p>
  
  <p>Drinking water is very important since it keeps your body (and your brain) hyrdrated, keeping the electricity flowing and helping you focus.</p>
  
  <p>Snacking and drinking soda can give you some carbs for bursts of energy. Several chess players eat pieces of chocolate to give them some energy.</p>

Answers.Text: I would add that you should get up and walk around once or twice during a game, if time permits.  And definitely engage in some physical activity between games.

Body: <p>It used to be a common problem for me to have very high calculating ability for the first few matches, and then I would make tons a blunders when I play the 10th or more. While for the most part memorizing lines, and having tactics become more inherent is allowing me to play more games, but I still can’t command the high level of analysis I would of at the beginning of the day.</p>
  
  <p>So how do I keep from my brain exhausting?</p>

  It used to be a common problem for me to have very high calculating ability for the first few matches, and then I would make tons a blunders when I play the 10th or more. While for the most part memorizing lines, and having tactics become more inherent is allowing me to play more games, but I still can’t command the high level of analysis I would of at the beginning of the day.
  
  So how do I keep from my brain exhausting?
