Mariánské Lázně Lesson: Pins Hurt

IN round one I reached the following position with black after White played 12.e5.
Black has two obvious moves (...Rb8 and ...d5) and two less-so (...Ba6 and ...Bd7) - which is best?

I protected the queen's rook by playing 12...d5?, but after 13.Bg5 f6?! (13...Bb7 is probably better) 14.exf6 Bxf6 15.Bxf6 (even stronger may be 15.Bh6) Rxf6 16.Rbe1 I was on the back foot against my much higher rated opponent (+419 elo), and succumbed rather easily.
Sacrificing the exchange with either ...Ba6 or ...Bd7 cannot really be justified either, which leaves 12...Rb8, which Stockfish16 and Komodo14.1 reckon leaves Black with at least the better side of equality.
LESSON: self-pinning is akin to self-harming, and should be avoided unless there is no choice.
