if your opponet plays the english most likely they are an extremely good positional player and know what they are doing probabley the best way to play is 1.nf6 so that white gets tempted into playing d4 where it would be normal queens pawn games
good idea!
I suggest 1...c5 and go for a hedgehog formation with pawns on a6, b6, d6 and e6. Try and trade off the c pawn for white's d pawn to get an open file for the rook on a8. Sergey Shipov has an excellent 2 volume book series called "The Complete Hedgehog". Volume one deals primarily with how to play against 1.c4.
