We welcomed a guest from Korea in our club. We tenukied hard at the start

You shall not have any other moves than

and

in the opening

(sgf file has two minor move order transcription issues during the end game)

A move to remember:

is personal joseki

with and without the marked black stone. Much better than a play at R5 or R6.

(a is good follow up for white if black plays tenuki)

is suboptimal

Moves to remember:

Black killed himself with this move. Do you know how to place the coup de grace as white?

I like reviewing my games as much as I like to play them. Go Pro Yeonwoo mentioned in her latest video how important it is to review your games. The said the Pros review several hours with their peers and she recommended to review a game at least twice.

There was also a thread about creating flash cards from game positions.

Problem 1
In this position is was uncertain if black should respond locally or tenuki and make a bigger play.
What is your decision? What are the biggest plays?

Solution 1

These are the big plays. A local play at H15 looses about a point.

Solution 4

Black has to go for the bold move at 1. It gets ugly afterwards, one variation is shown. But fights like these are the essence of go and no reason to chicken out.
