Mexican defence

Sort:
Poryg

What is a difference between orthodox and unorthodox? I don't know. I just know that I feel like I should say it here, because this opening feels like it needs some more awareness.

Mexican defence, known also as Mexican tango or 2 knights tango, is a very rare and theoretically unknown defence for black. It is simple and easy to use and unlike most offbeat openings, it is perfectly sound!

This opening starts with 1. d4 Nf6 going with 2... Nc6.

What is it's use?

While this opening is not that sharp, it is not toothless. Simply because it is incredibly versatile. You can transpose to many openings, most commonly to KID.

How to play this opening?

White has an immense amount of choices here. He can for example go for 2. c4. In my experience after 1. d4 Nf6 2. c4 Nc6 came 3. d5 most often. Against this I usually play 3... Ne5 with fighting against the overpassed pawns like in Alekhine. Unlike Alekhine the positions aren't that sharp though.

Whatever White plays, I hate it when he plays 3. Nf3 or 2. Nf3. Against this I usually transpose to stuff like Chigorin defence to Queen's gambit, because I am deprived of the possibility of 3... e5.

When I am allowed 3... e5 though... Sharp fights always starts smelling in the air!

I know no theory about this opening, so I will say no more. In the second topic I will just present how can it look like when your opponent not only allows e5, but even e4,which any reasonable d4 player should know as an inexcusable mistake!

game number 1. Except for the blunders in the end it simply proves the point.

This game should be more interesting. It is a game where White could surely get away with allowing e4, but played too passive. So a lesson for players, never play passively!
