Technically white can block with rook check with the queen, too, on a4. White will obvs lose but it'll take a bit longer navigating to the exact mate

Blocking would have been good because with Kb2 I can automatically see the mate.  With the blocking, even though they lose material, I couldn't see the forced mate as that's still 7 moves out.  There's a chance I would have misplayed

Yup, there are just so many routes and they all lead to mate.

At least you got the idea to sac the rook. In the game, my opponent didn't even block with the pieces to delay the inevitable but went Kb2, so sacrificing the rook on a2 comes with a check... Next rook replaces it, and then queen delivered mate in the corner
