saw1c 4d vs AhSayuni? 4d  

erkkierkki?: This is my try (black tenuki). My key stone is whites number 5. Black should cut losses by playing 'a' or just answer to initial move from white.

Black secures  

togo: This is better than nothing, but now black+square secures nearly everything, and in sente. This is also better for Black than playing B2 on a. This does mean that this B2 here is good, because White could have played a better W3.

My attempt at best play for both.  

edmundangles: White can do better than catching 4 stones. After W1, black gives up his big group and saves what he can.


edmundangles: Black looses 4 more stones in connect-and-die.


edmundangles: Same result as above.


edmundangles: Connect-and-die even sooner.


edmundangles: Doesn't help. W3 at W5 works as well.

Good solution  

W1 is good, but we haven't seen Black's best answer yet. Also there are more white plays: Which? Are they better? Worse?
