Adapted from Myungwan Kim 9p:


  • Take the corners
  • Enclose, approach, or invade the corners
  • Extend to the sides

Middle game

  • Attack your opponent’s weaknesses
  • Defend your own weaknesses


  • Who’s got more stones?
  • Who’s got more liberties? (Capturing race scenario)

Attacking: Know why you are attacking. Set the aggressiveness of your moves appropriately.

  • You can get benefit elsewhere while attacking
  • You can kill outright

Invading: There are a few ways to save your stones. In order of preference:

  • Counterattack. Disconnect and capture your opponent’s stones. Look for crosscut opportunities. Be aware of capturing races.
  • Make a base. Make territory while living.
  • Run into the center. Connect to your other stones.
  • Live inside, either by making two eyes or maybe seki.

Common kyu-player mistakes

  • Not thinking. Think 3 seconds at minimum before playing a move. You will catch a high number of your mistakes this way (it’s too easy in online games not to spend 3 seconds!).
  • Focusing too much on one area. Don’t follow your opponent blindly. Always look for ways to take sente.

Becoming dan level

  • Read. Always read 3 moves: your move, your opponent’s likely response, and how you will respond next.
  • Always look for weaknesses in your opponent’s stones
  • Try to make your stones globally efficient. Try to make your opponent’s stones inefficient.

Difference between territory and influence

  • Territory is cash, worth the same in the beginning the game as at the end of the game.
  • Influence is an investment for the future. It might not be useful near the end of the game, but it’s more valuable earlier in the game.

Making a Move

  • Evaluate your position. Are you winning or losing? Play more aggressively if losing; play safely if winning. Where are you strong or weak? Where is your opponent strong or weak?
  • Generate candidate moves
  • Read through the likely outcome
  • Evaluate the outcomes
  • Compare the outcomes
  • Choose the move that will let you win
