  1. As usual, the hard problem all comes down to timing

    • David Ormerod says:

      Indeed Tony. We could also substitute ‘Go’ for ‘the hard problem’ in your comment ;).

  2. jangalf says:

    nice problems. I like the level of the problems. Good collection you have here David.

    • David Ormerod says:

      Thanks Jangalf, it’s built up slowly, but I guess we have over 100 problems now :).

  3. ZeroWave says:

    Why is the descent bad at the hard problem, at all variations? Does it simply not add anything? I lived with the descent seven times without understanding what I’m doing wrong…

    • David Ormerod says:

      I assume you mean the descent at A3? Yes, it doesn’t add anything to intersperse the descent. Just the threat of playing it is enough.

      If you exchange A3 for A4, it’s a small loss for black because (if the sequence then continues to give a similar result to the solution diagram) white can connect under with A6 by squeezing later. Since black might want to attack white’s outside group later, black would prefer not to make that option available to white.

    • David has, as always, precisely answered the question. But as a general principle, a threat that doesn’t have some immediate effect is best left until it can be used as a ko threat/ladder break/miai. You don’t know how you may want to use that threat later, best to keep your options open.

  4. scwizard says:

    I got the answers to questions 1 and 2 right first try. It was mostly on intuition though, and knowing what was wrong rather than fully reading out the correct variation.

    As for the third problem I got the first two moves, but I didn’t get the “Knowing the best time to ease off.”

    It’s so hard figuring out when to settle a fight!
