Here stockfish choose to keep the dragon bishop than capture the rook in the corner. Rook need open files to be effective.

For the exchange white got a pawn and opposite-colored bishops. Also it's not clear how black will be able to release his queen from custody. Interesting position albeit stockfish display -1.23 advantage for black. The game is ongoing and can be followed live. r1b2rk1/p5pp/2p5/R4p2/8/2NP4/P2P1PPP/q1...

Checked with latest stockfish dev. Study found inside the book "Brilliant Chess Studies" released in 1997 on page 83. Stockfish display evaluation score of -2. Such evals is usually a indication of a possible cook in the air. 1b6/1P1pp3/P1pkNpb1/2p2P2/3pp3/8/1B5K/8 w - - 0 1 [Event ".hm Shakhmatnaya...

Do this qualify as test position?
