1. Bb2 forces rook exchange and you can comfortably chase down his bishop and pick off pawns with your queen now that his only credible mating threat (two rooks with the restricted king along the first rank) aren't forcing her to hang back to guard the first rank.
I dont like the look of bb2 (though I think you mean bg2?) because it leaves our bishop on a worthless square. I think Dynasty's plan of qd6 is good, though Im still not seeing a line where we get in trouble immediately taking on b4
edit: if theres a reason why and someone could point it out that would be super
I think I mean Bg7, actually. I don't think the bishop is much more than a glorified pawn until we free the queen to go pawn-chomping and give it some dark-square real estate. I only went with it because it was simply the fastest way I could simplifying without giving up the material advantage.
Given we have such a massive edge I'd rather give a theoretical 0.1 of a pawn and steam-roll rather than worry about keeping the game pointlessly technical when I am the only one who has something to lose.
Also, I'd overlooked ...Rc7, which leads to mate. So it's pretty bad to play Bg7.
