How's this: Let's play an unrated two game correspondence match. I'll play the Black side of the Budapest, you play the Black side of the Albin. We both can use engines, so the games won't be determined by a simple tactical oversight.
Btw, I don't play the Budapest as Black, so if you play the Albin you may have a slightly better chance of surviving.
What do you consider the critical line against the Albin? Or some critical games, if not a line.
