Surviving a frightening position

After a hiatus of several months, the Gabridoodle was finally back at Boston's South Station for the monthly simultaneous exhibition given by Grandmaster Larry Christiansen. There was a full house, so the Gabridoodle only got in two games.  He lost both but each went more than 30 moves, a small achievement.

In the second game, he managed to survive this frightening position.  Oh, sure it looks tame enough, but in fact, all hell is threatening to break loose.
