Tactics: Benoni Bombs

This week's Canadian Tactic comes from the final round board 1 game of the 2017 Ottawa Winter Open between Svitlana Demchenko and David Gordon.

Black needed only a draw to clinch first place; but played the Benoni anyway. Clearly, there are some players who even today have learned little from Mikhail Moiseyevich Botvinnik -- Patriarch of the Soviet Chess School -- and still prefer to imitate the hooliganism of Tal. :)

White has just played 26.Nc4, going after Black's backward d6-pawn. What should Black do?
