A Ryder's Gambit in the Wizard's Castle

Today in his blog, The Wizard's Castle, Eric Shoemaker annotates a Blackmar-Diemer he won in the Reno Club Championship Qualifier:
"I knew I would be facing the speculative 'Blackmar-Diemer Gambit' but was more prepared for one variation than the other. This led to me getting into some difficulties early on, in which I should have lost. I did not lose, however, as I went in for really sharp play with 29...Qd8! But it's possible that I'm still lost with best play after this move; however, it was the only feasible possibility in the position. Alternatives did not seem to offer any chances of success."
Here's the game and my take on it, with a little help from Rybka. You can find Eric's notes here.
