A simply hideous move: who would think of allowing the queen in at d3? Especially since 12.d3 retains a normal position. '''12... Qd3! 13. b4 Bb6 14. a4 bxa4 15. Qxa4 Bd7?''' Black could have played 15...Bb7! maintaining control of a6. '''16. Ra2?''' The queen should have been dislodged from d3 by 16.Qa6!. '''16... Rae8''' With the threat of ...Qxf1+. '''17.
