The General
The Wicket Keeper is the engine room of the fielding side. It requires the highest level of concentration, agility, and glove-work precision.
Stay low until the ball is released. Your weight should be on the balls of your feet, ready to explode laterally in either direction.
Always catch the ball with 'giving' hands. Move your hands back slightly upon impact to dampen the force and prevent fumbles.
Blind Catches: Have a partner throw balls from behind a screen. This forces you to react instantly to the ball's trajectory as it appears.
