Which opening to adopt against d4 as black?


Yuo have to decide how much theory u want to learn/ as the QDG, Slav. @KID are all theory heavy. THe dutch is fine/ personaly I dont like the indian defenses, and i play the benoni systems and i use the QG accepted s my backup. The benoni isnt popular above
2300 but for us its very playable/ u have to get used to playing with a lack of space though.. good luck
later dudes
