i never used this opening before 

This is only good if you are really in need of rooks form the mid game.

I personally do not prefer this opening if playing against a good player.

my game vs. steelpants

Exactly.

what's the use of the opening?

I like to use it but not often it keeps your oponent guessing just enough to suprise them most of the time

This isnt the best opening, mostly because you're only opening 1 of your pieces and you completely ignore the center, which is the most powerful.

Kadas Opening is a good opening for prevent 50% of scholarmates

It's awesome opening.

But the bad things is that every troll come here and post a bad comment.

this move is great if your great, and your oppenent is just mediocre; really makes them think "wth", and then you annihalate them lol

it is a good opening if u know how to use it..

someone here mentioned about rook not being safe : yes good sacrifices should be explored... after all.. ur objective is to checkmate the king..not to preserve all your coins ;P

here is a game i just played now..and won.. i used this opening as its my fav.. but i never knew it was called as kadas opening.. it is a new info for me!! ;P

yes

if black is not that cooperative, you might end in something like these variations names: Koola-Koola (1...a5), Wulumulu (1...e5 2. d4), etc...you know that the fifth variant of this "opening" is a symetrical move (h5) - I mean what else is there?

It was probably blitz anything goes.

I think that some 2100+ guy on live chess played this against another 2100+ guy, and won.

people think its awful  but  if u dont understand the  the  line then dont use this  v opening

this opening is for getting your opponent stunned and surprised , but you have to play sharply ...
