The Colorado Counter

U can't evaluate an opening if you dont know the main idea behind it

And i'd say black's king's side structure is much stronger than white's one.

True, I don't understand exactally what black should do in this opening :)  I have an idea, but I don't know what is best.

it is all very sharp tactics nothing logical about it, which is why i think it does see some play at the IM level...i love playing the line, but I often forget the moves, it is almost all memorization, it is very difficult for me to find the right moves over the board which is why it is so cool to play, nothing is logical, i too subscribe to Gunjan's videos and really appreciate the work he has done with his gambit lines, my favorite games are when white pushes e5 and i get to play d6 and get a nice pawn center... then its all logical and memorization is not so vital, if you have a good memory it will definitely boost your rating

I've played 3 or 4 games with it. It's a very strange opening for both sides...white think they'll easily poke through the defense. Black tends to stay mostly on the defensive but played right it's a tough nut to crack for white and black can later in the game get some good counterplay.  

Most definitely leads to some interesting games. 

Colorado Gambit is a good opening. Search on Youtube for GJ chess and colorado gambit, very good videos.
