my friend showed me this opener

what do you guys think?

I think if two fairly good and equal players played from this position, white would have like an 80% chance of winning.

?? ('opener'?)

yeah, i'm not sure that's such a wonderful opening, though you never know, its really about what you want, maybe you'll find that it comes in handy against opponents who throw their weight against  f5 and c5, but i'm pretty sure i learned in chess club in lower school that "knights on the rim are very dim" :P

i resent that statement. how can white effectively advance?

well black is really surrendering the center  LOL

not at all you fool

How can white advance? Well, I'd start by advancing to d4, not d3... play nf3.... I might trade my c bishop for your knight on the h file- I am usually loathe to trade bishops for knights, but it would really mess up your kingside structure, and remove the protection you got on the f7 square from your knight. To be honest, it doesn't look that great of an opening.

It is general chess consensus the knights on the outside of the board are bad, unless they have a specific purpose. Think of it this way: A rook on the outside of an empty board covers the same number of squares as a rook in the middle of an empty board. Can the same be said for a knight? No... and so knights are better on c6 or f6 than a6 or h6. (Let it be noted that while bishops are also less effective on the outside than on the inside, they still have the long diagonal, so the effect isn't as great.)

 Er...With a pawn? Or maybe just take the knight (I prefer bishops to knights but oh well) and then go for it =S?

it is powerful because it is unexpected.

It may be unexpected, but it certainly isn't powerful. This type of opening is one where White will have no trouble gaining the advantage if he sticks to opening principles. Granted, the improvement of d4 over d3 could be made, but Black still won't be able to do anything against a good opponent.

What do I think? I think those two knights looks pretty sitting in the corner hiding from the inevitable

I doubt anyone would play d3 over d4, but... Nf3, Nc3, Bxh6, d4, Bc4. White has a good edge from this opening. As for your "It is powerful because it is unexpected" comment, that is no reason to play an opening. Black is developing his Knights, sure, but not to their best squares. The knights are out of the center, and not protecting much. I suppose Black can follow up with c5, and bring out the queen, mounting a somewhat effective Queenside attack, but all White should do is castle kingside and no more attack for Black. EDIT: It isn't a good idea to call more experienced players "Fools".

unexpected and powerful go hand in hand: unexpecterful

in many positions in kings indian defence both knights are on the edge but it still works. :)

Why do you want other people's opinions if you aren't going to listen to them?

but, if the black moved his pawns ?

Any strong player would be able to exploit Black's position -- not to immediately win, but to keep strong positional pressure on Black that would probably lead to concessions and a terrible game for Black. 

If you want to say "But it's unexpected!".... well, maybe a weak player would not know how to exploit it, but a strong player sure would.

If you're so cocky and confident that this opening is strong, why not try it against players rated over 1600?  I think you'd be a little quieter about this opening after that.

Surely you give up the powerful position of centre board with this opening and hence would not use it against an equal or higher opponent

if i play 1. h4, it may be unexpected, but you can't say it's powerful.  I personally would trade my bishops for the knights, because the doubled pawns are even worse on the rim then in the center.  not only can they not support each other, they can't support any other pawns and can only capture in one direction.  it's pitiful.
