Funny you should mention about landing gear up in an emergency.
At a Bonanza proficiency course I attended a few years ago, a well respected guest instructor from the States (and experienced others)advocated landing with the gear DOWN to dissipate energy. He also reckoned that directional control by the nose wheel on the initial ground contact could determine what you ran into! The view was that the gear should be lowered unless water or known soft surface would be encountered upon the forced landing. I often debate within myself, what would be be the best choice, if ever faced.
It would be hard to know what to do before the event. I don't think you could blame that guy for leaving the gear down. From the air, and in that situation, it probably looked a pretty good place to park.
Sad to see a nice Bo end up like that. I'd love to know what caused the engine problem
