was this a bad play?

i'm just moving to six max tables from full ring games and am playing more heads up to four handed tables. i am not very experienced at short handed play and i am pretty much experimenting. i just sat down and i don't have stats on either players yet but the sb just went four bets on the flop with middle pair and no draw the previous hand.
