Play a game

Which side first Timing

Two jobs; the difference is order. You played here; the better move is far away.

Settle your group first A base

The better move sits on your unsettled stones; you ran out or up. Not a life-and-death problem.

Take the ko, or not

There is a ko: take it, or play elsewhere. Not hunting ko threats.

One of two places Miai

Two distant places; playing one gives up the other. You took the worse one.

The move you didn’t see

The point does not look like much at first. After you look, it is the move. Not the vital point of a shape.

This corner you keep missing

Still in the same corner in the opening, not one of the usual plays. Not a joseki name.

When ahead, keep it simple

You are already clearly ahead. Take the profit. You started a fight instead.

These are choices on one move. Full list: What we drill.
