In the following game, White has just played i2. Black is thinking of resigning.

Is there a way for Black to avoid defeat?

[game;id:959952;move:46;title:Black to play (and win?)]

[perhaps worth clarifying that the game has now finished on the server, so yper's question is “theoretical”]

That was rather obvious, wccanard - I'd never suspect Ypercube of asking for the solution to an ongoing game! :-)

There's no short way to black win :P

I1 or H1, A15, H7 :P To make game longer but not sure about end result :P

I nead a program to check it offline :P Can I get it somewhere??

here are coordinates:

(A15 does not exist here …)

But: black wins in the game, so you should ask: did white make a mistake?

e12 it should be :P sorry ;D

You are right ab (and Marius).

Black did win the game, after playing the obvious h1 defense first.

So, a better question is. Where did White make the mistake and how could he have won?

50.A6 by White was a complete waste of time.

Without looking at it too long or too deeply, after 49.B5 by Black, my first reaction is for White to play something like 50.D5. This threatens a ring by playing at C6. Black must block in that area and then White can then play 51.C3 and prevent Black from connecting along the A edge.

I think White was ignoring or missing your threats during the last for or five moves.

You are right.

Marius suggests 48.j1 for White instead of the 48.a1

48.j1 49.a1 50.c2, and I don't see any hope for black?

You meant i1, no ?

I think i1 is clearly the logical move : blocks the lower black group from making a fork and you still have one turn to block it from being a bridge.

Yes, I mean i1, of course…

After 47.h1, 48.a1 wasn't necessary. Bridges are easily cut. White should have played 48. i1 instead killing the black stones!

49.a1 50.a2 51.b1 52.c2!

Silly me: I realise Marius and alda commented the right move!

For Richard: It would be nice to have the coordinates on every board as an option.
