1.c4 e5 would be fine were it not for the "Kramnik recipe" of 1. Nf3 and 2. c4.
An answer to the English could be the Symmetrical Variation: 1. c4 c5.
A repertoire incorporating the Hedgehog and 1. c4 c5 2. Nc3 Nf6 3. Nf3 Nc6 4. d4 cxd4 5. Nxd4 e6 would have the bonus of giving rise to similar structures as arise in the Nimzo and Queen's Indian.
Of course, move orders are vital in the English because it is a highly transpositional opening, so be sure to look at those carefully.
Hi, all
I am just wondering what response to C4 I should look at. I am a e4 player and against d4 I play the Nimo/queens Indian.
