Reading Problem 1 / Solution

Sub-page of ReadingProblem1
B 3 is the key.  

W2 is the natural response to B1. B3 captures the white+circle stones.
If White stubbornly resists with W4, B5 prevents escape. Then,

No way out  

Black gets full work out of black+circle.

Capture one more?  

SkyCrashesDown: Doesn't playing B3 here instead capture an extra white stone white+circle?

Black's failure  

JanRamon: Not really. the one white stone white+circle is not so important because now the two cutting white stones can escape with W4. Up to B7, Black can only capture these cutting stones in ko. If White wins the ko, Black's center stones are dead.

One simple variation  
The other route fails because of a and b c d
