Here is a nice problem from the Tactics Trainer that completely stumped me. 

After 11:32, I finally moved 1... Bf3+ thinking that the problem was calling for simplification.

I did not see the interference solution and so this is a good one to add to my database of patterns to practice.

I'll call the pattern Split the Rooks.
