Preflop: Hero is BB with A:spade: , 7:heart: . MP3 posts a blind of $0,25.
MP3 checks, CO folds, BU raises, SB folds, Hero calls, MP3 calls.

    Which chart we use for our preflop play: "BB defence" or "Actions against 1 raiser ( and 1 caller)" ?

Also to the question is there some SB complete chart? Or we always raise?
