In Response To: Routine position: cube action with open six (Klaus Evers)

Well, finally my partner Martin and I made the right decision. Martin was more confident than me about the double.

I still find it not easy to judge this position, despite all the information from the DQR and Kit's excellent book.

Anyway... they might even pass! (Which they did not).

This came up un the second round of double consultation against the later winner 1-Ufuk Aksak & Erhan Yenisen (Turkey)

Congrats BTW!
