Kim Myungwan, Korean 9d professional, dropped by Harvard and MIT's Go clubs this past weekend to scout out the collegiate Go scene. He gave a short review of a game between Evan Cho, a former Korean insei, and Ryan Li, recently minted 1d American professional. During his review, he applied general principles of Go to make comments on the players' moves.
- Take the corners
- Enclose or approach the corners
- Extend to the sides
- Attacking your opponent's weaknesses
- Defending 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, order of exploring possibilities:
- 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
- Contact plays are almost always a mistake.
- Think 3 seconds at minimum before playing a move. You will catch 80% of your mistakes this way. (Online games are bad because it's too easy 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
- Reading. 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
