What the heck is the purpose of a Knights' Tango opening?


well it opened up the scope of most of my pieces so kinda developing.

Normally, the knights tango opening is very good for taking opponents out of theory, and if you know a couple things, it can be VERY powerful. However, if white knows how to play, it can also be very very risky for black.

blacks pieces are in great squares. the knights are ready to pounce in a kingside attack, the dark squared bishop is a monster and the light square bishop is usually saved for the endgame where the pawns on dark squares make it a harmonious piece.

I am sorry, but could you tell me the purpose of a5?

Hi!
The idea after 1. d4, Nf6, 2. c4, Nc6 !? is to play ...e5 challenging white center, for instance if 3. Nc3 then 3...e5. Or if White pushes 3. d5, then 3...Ne5 followed by ...e6 counterattacking the center in a hypermodern way. Black has to be comfortable with somewhat cramped positions that may arise and White should not overextend. My impression is that White has the better chances and the easier play. I would not recommend this defense for beginners.

Good luck!

white knows the c5 bishop is powerful, so na4 is coming soon, a5 allows the bishop to retreat also a5 stops a3-b4

Thank you! I have seen that type of move in a lot of master games (especially in the guioco pianissimo)
I was in a game and I started with d4, then my opponent proceeded with the Knights' tango opening. It honestly just wasted all of their time because I was developing almost all of my pieces by sending out my pawns. I ended up having a 12 point advantage complete with their queen before they resigned.
