It appears to me to be a variation on the live in the middle invade every corner strategy and or diagonal great wall as well as a bit of the bean scattering strategy.

I myself play a somewhat unconventional fuseki, however I find that I also fall into traps of unconventional play when I encounter them, I think I am used to playing against conventional fuseki.

The real mistake, is to not react to the unconventional plays. IE tenuki and continue to play the opening that you are familiar with, since the conventional plays will probably be sub optimal to the unconventional opening that is tuned against it. I find most of the unconventional openings are designed to give some advantage over conventional openings and aren't necessarily all that great in general.

Uberdude's response is spot on I think, but I want to add something to it concerning thinking strategically.

Because it's important to play with a plan, it's important to try to understand the meaning of your opponent's moves. When they seem like garbage moves, one way to try to understand them is to try to disprove the notion that they are garbage. Figure out a way in which they might be good and useful moves.

In this game, I look at the position up to and I can see just one potential use for his stones floating in the center. That is, establish influence in the center with floating stones and take the 3-3 points of the corners. In the sansan invasion josekis, this might reduce the influence of the wall that you'd get.

Yes, this is a one-dimensional plan you're giving him, but it doesn't matter if you're complete in your assessment of his unconventional strategy. You're just using it as a starting point for your own planning. Then, as Uberdude says play solid shapes.

I was going to say the same thing, only without looking at the opponent's other games. Once you see a move like , you know immediately that was planned from the beginning. There are various box formations. If you take double wing and then add a stone in the remaining corner of the square, you get one. So in a sense, allowing a big square box is tenuking from a position that is already a double wing. Maybe his strategy is to learn whether such a shape is as effective in the middle of the board is it would be near the sides and corners. It is not an idea to be dismissed out of hand, just because we've moved past the Shin Fuseki period. On the other hand, he seems to be combining with a greedy approach. He can't get everything, so you have to decide what you want.

Hope my advice help..

how do i play him? before that something i have noticed from the game.
1) he is much stronger player than you are. which means he will beat you even if he plays conventionally.
2) although you played three corners..black's influencal moyo looks bigger than your points.

now.. when he plays inthe middle..you play same.
when he takes points..you do same.
as long as you maintain the balanace...you are ok.
i am not saying that my way is correct but i would never play three corner if my opponent plays such moves.
