These are the very first moves of a game played by a shodan player (white) against me (black). What do you think of this opening? Is it just nonsense or does it have a meaning to play :w4: after :w2: ?

If it has a meaning, which fundamental principle of go would explain it?

A position search in senseis revealed no results.

:b3: is just first instinct, but is it wrong?

Black 3 is a fine move. I'd say that you are playing well and that he is playing very badly. If you continue with 5 like this you have him split.

Now maybe there is some hamate that I do not see, but I call this a huge local advantage for black.

EDIT: It is so contrary to the principles of good play that I'd suspect that it was a mis-click, but he was to proud to ask for an undo.

It's probably just to confuse you. If you play Joaz's :b5:, you can think of it as at worse a 3-3 invasion, but with white having stupidly exchanged :w2: for :b3: first. There's no way that makes much sense for him.
We don't know who we are; we don't know where we are.
Each of us woke up one moment and here we were in the darkness.
We're nameless things with no memory; no knowledge of what went before,
No understanding of what is now, no knowledge of what will be.

Thanks for the replies. I also guessed it was just to confuse me, but may be there is a kind of trick involved somewhere.

After Joaz's :b5:, I guess he has to live in the corner immediately. Normally 3-3 invasions end up with invaders sente, but in this case I would probably even keep sente due to :b3: (???)

That's of course if he manages to live at all...

I guess the expected "best case" continuation would be a completely shut in group of 2 or 3 points in gote for white, and thickness in all directions in sente for black. Worst case would be a ko or even direct death. That is IMHO bad enough to seriously consider *not* trying to live with :w4: (but then again, I wouldn't have played it in the first place :P)

2: "I'll just play something fun here/I want outside influence/Let's see what he does/I'm asleep/There's not enough handicap/Let's keep the game close/etc"

4: "Oh, that corner looks kinda big. I should invade now, one move before it becomes territory."
That which can be destroyed by the truth should be.

It is nonsense. ;)

:b3: is good. Joaz's suggestion for :b5: is fine. :)

Wait till Ed Lee sees this! :mrgreen:

Doesn't look good for W ... but, perhaps if he's trying to play tricky and trip you up, he should have tried something slightly different:

This is more interesting, but I still wouldn't play this as W, I don't think ...
