Chess bullet game Dutch Stonewall system: tactics, themes, blunders!

This video features an exciting Stonewall Dutch bullet encounter, against a much stronger player (+450 rating points). I come from a Bishop down, to go a Bishop up, and then — under time pressure — attack instead of defend – with disasterous results! Panic ensues, and an under promotion leads to a rather cool checkmate (a mercy killing)! Once again, I guess it’s true, “The hardest part of chess is winning a won game. – Frank Marshall”.
