Subject: Test position

Hi!
Here's a position from a game I played some time ago:
[D] 2bn1rk1/4r2p/p2p4/1ppPp3/5p2/2P2PP1/PP1QNKBq/3R3R b - - 0 27

It's clear that black plays Rxf3+. But which program is able to "see" that white
already loses the queen?
A possible variation could be:
28.      - Rxf3+
29. Kxf3 - Rf7+
30. Ke4  - Qxg3
31. Rdf1 - Bf5+
32. Rxf5 - Rxf5
33. Rf1

Until here, everything seems to be forced (please correct me if I'm wrong).
[D] 3n2k1/7p/p2p4/1ppPpr2/4K3/2P3q1/PP1Q2B1/5R2 b - - 0 33

There doesn't seem to be a defense against Rxf1 and Nf7, after which white will
have no real defense but giving his queen.
So, which program is able to see the lose of queen already at move 28?

Regards,
Steffen
