I've recently started to play the triangle system against the Queen's gambit, and so far it is okay. I've extensive knowledge in the Noteboom variation, but the problem with it is that the variation can be easily be avoided by White (since it is such a sharp line).
So I decided to search for a fall back plan.
I mean, I've just been doing the automatic c5 counters when Noteboom was turned down, but I've stumbled across this system called the Meran system.
Can you tell me the theory behind this system?
On the surface it looks like Black is supposed to advance on the Queenside, but I'm fuzzy on the details, nor this "Anti-Meran".
