I would have liked to see the move sequence of that Timman suggests after 1. Qxb7 Rxa5 ... My guess is that many programs will see a transposition between Qxb7 and Be4. For example, 1. Qxb7 Ra8 2. Be4 vs 1. Be4 (black plays some move to avoid the threat of Bxf5) 2. Qxb7 ... I disagree that this is a good positional test that only the strongest of programs will find.
