analysis of famous baduk record 33-47

If black dominates lower left side, black A is better.

 

 This is also good.

 This result seems good at white, but, black player didn't think so.

Anyway, white dominates upper left side.

 

 This is very big.

 White expects the sequence up to 5,

and white player already imagines this sequence from white A.

 

 Of course, black player knew it, but meekly followed it because the next black movement A is great.

 

 

White 1 is important.

 It's very painful for white.

 

This is great point.

It helps upper right side and weak group at center at the same time.

 If A become black turn, this is a pae.

Moreover if white lose pae, white group of upper may die.

So, white 4 will prevent from pae and capture black group.

But, this is double pae, and if pae create otherside, black has infinite pae threats.

 

 

 This is also good.

A is weak, 1 is good.

And next-movement B is also good.
