I’ve been playing Go a bit of late, and a friend was taught this about openings, during a review of a game on KGS. Posting it here mainly so I remember for the future! 🙂

Teofrostus [2k]: when you're playing go, there's a nice checklist that you should go through during the opening 

Teofrostus [2k]: it goes something like this 

Teofrostus [2k]: 1) Do I have any weak groups? 

Teofrostus [2k]: 2) Does my opponent? 

Teofrostus [2k]: 3) Are there any unapproached corners? [opponent corners before allied corners] 

Teofrostus [2k]: 4) Are there any "big points" left? 

Teofrostus [2k]: and you should respond to these in this order

Also worth noting:

Teofrostus [2k]:it's something that you should follow until you're like 3d
