There are 2 types of hand :

• hands where the player was at showdown (SD, if he has the best cards, he wins. Otherwise he loses).
• hands where the player was not at showdown (WSD, if all other players fold, he wins. Otherwise he loses).
  
  

Net with showdown (Net SD) can be a sign of the following patterns :

• the ability to grow pots when the player has the best hand
• the ability to detect bluffs
• a tendency to be drawing dead
• a tendency to keep pots too small
  
  

Net without showdown (Net WSD) can be a sign of the following patterns :

• the ability to bluff a lot
• the ability to bluff in big pots
• a tendency to let bluff
• a tendency to play too tight
