In Poker, a good player is called "shark", and a bad player is called "fish".

Since poker is a pure skill game (no luck decides on the success in the long run), the sharks win the money from the fishes. So the sharks "eat" the fishes.

 A shark:
- Plays regular poker
- Learns from his mistakes
- Reads poker strategy articles and books
- Plays to earn money
- Plays with rakeback
- Creates his own strategies
- Sees poker as 100% skill game
- Always wants to improve his game
- Watches his oppenents
- Is a winning player!
- Doesn't go on tilt, because he knows that luck will change
- Plays concentrated
- Plays aggressive

  A fish:
- Plays for fun
- Doesn't care about his mistakes
- Thinks poker is luck
- Hunts for bonuses, but don't care about rakeback
- Is a loosing player!
- Only cares about his own cards
- Is not patient, he wants fun and therefore action
- Don't understands any poker maths
- Overplays suited cards and draws
- Goes on tilt fast
- Is on telephone etc. while playing poker
- Plays passive
