queen exchange "mistake"

In this game, on move 33 I forced a queen exchange with the idea that the white rook would be forced to stay on the first file. The computer analysis classified the move as a mistake and listed 33... Rxd2 as the "best" move. However, this allows the white queen to move freely (to a point).  Is this just an... "oversight" of the computer or is there a reason why 33... Rxd2 is a better move?

I generally use chess.com for analysis (quick) to do my analyzing but I'm considering using chessmaster (my learning tool and if any other novices see this, GET IT, tons of interactive lessons and an expansive opening guide) to analyze. Especially if I (an admitted novice) can think further then quick analysis in the blink of an eye.

It would be easier if you put the board up, since the page is unavailable.

Put the game on this forum.

Ah, thank you AiryNeon, I was unaware that others could not view that page. I inserted the game at the top of the post.
