    Took me a while, but I finally go the hard one! Top two were very easy. Hard one is a great problem!

    Yeah, the medium one was almost too easy – I kept rereading and checking my answer because it seemed to simple to be right!

    The hard was as last week very clever. The right move looks like what a 20k player would do, not like the right answer. I confess I gave up and clicked around until to find the final solution, I never even really considered the right answer.

      What’s interested me about doing this so far is that different people’s judgement about the difficulty of problems seems to vary enormously (including my own). I thought the second problem was quite a bit harder than the first! :)

      You can download the SGF if you’ve given up and just want to see the solution. The first variation in the file is always the one marked ‘correct’.

        I agree, David. The first one I saw at first sight, the second one is not so difficult, but training you to say goodbye to stones for the good cause. In professional games I always find this fascinating: some stones are played to try to accomplish something, often under unfavourable circumstances, and are then abandoned under the threat to do something with them, like connecting with them from the outside, whereby the result is better than with no sacrifice at all. In problems this often is clear cut, in games not so.

        Kind regards,
        Paul

          Yes, sometimes it’s really hard to understand why stones are sacrificed. I smile when I read a commentary that says something like “fighting spirit dictates that white should give up these stones and continue attacking on the left”. Occasionally I wonder whether a bit less fighting spirit would’ve given a better result :) .

    Funny enough, the first problem had me thinking for a few moments it was White to play. Once I got that, it still had a decent width (about 4) and a depth 2.

    The intermediate one on the other hand was about spotting the miai after the correct move, so I agree it was easier than the easy one.

    The hard one, I have to admit, went into trial and error mode.

      It’s the opposite for me. The first one I classed as ‘solve at a glance’ for reasonably experienced players. The second one is busier and requires a little thought to see what’s going on.

      Clearly most people so far haven’t found that though. Maybe I misjudged them a bit this week :) .

    The most interesting variation to me is Black C3 btw.

    Would you mind putting the answers down? My computer doesn’t always say which is correct, plus I have found many variations for even the hard one, but I never know what White might do next!

      Hi AJ,

      Have you tried downloading the file using the [link] in the lower left? The correct solution will be the first variation.

      If you need some software to open the files, let us know which operating system you have and I’m sure someone here will be able to advise you. :)

    I found the second more difficult then the last. Mainly because the second problem had “too much stuff” going on and the last one was pretty clear cut. Placing threat in place to secure larger gain. First one was a walk in the park but its a good problem to learn to read these situations (since they are quit common).

    Thanks again for making my morning coffee brake enjoyable :)
