The story behind the detection of 51 Peg b includes both intensive and state-of-the-art technical development and scientific perseverance, mixed, as most great discoveries, with a little bit of luck. It was the product of a RV blind search survey of FGK stars started several months before. With the launch of space-based high-precision photometers hunting for transiting planet candidates, their ground-based follow-up using high-resolution spectroscopy now occupies an important part of telescope time, relegating RV blind searches to GTO programs of instrument consortia. There is thus few room for the community to design such scientifically rich surveys. However, the Calar Alto Observatory opened a call for this in 2020, in a unique opportunity to design niche-oriented legacy programs. The KOBE experiment was awarded with 35 nights/semester with CARMENES to look for planets in the habitable zone of late-type K-dwarfs, a very unpopulated parameter space. Since then, more than 2000 spectra of 50 K4-M0 stars were taken, representing optimal environments for planet detectability and life development. In this talk, I will present the status and results of KOBE.
