Corner fun

Did you ever think about that it never matters which of the two moves in the corner you play :) most of you probably have, but the realisation didn't come to me until a few years ago when I programmed some D&B software. I just thought of it and thought that maybe someone didn't think of it :)

good day

Yes, for some reason this was really hard for me also. I realized it only when I thought about the String and Coins equivalence.

Sometimes I'm spending multiple minutes thinking about which of the two moves I should play. I know it absolutely doesn't matter but then I just can't ignore the optical difference and try to optimise the "beauty" of the board as much as possible. When I'm done choosing I realise that I totally wasted my time again and that just makes me sad every time. The title is a lie... it's more a corner frustration than anything to be honest.

I agree with the description "fun".

That was the first discovery that I made that made me want to write The Shark.

The second was the hourglass:

After b1, a2, e4, d5 -- all four moves which give up a box are equivalent.

Well I am glad I was not the only one who didn't see it immediately :) sorry about your corner frustration purgency.

There are plenty of these, for example in this position g6 and e4 are equivalent or here i4,h3 and j3,i2 and k4,h1 are equivalent.
