Flavor physics is a powerful venue to indirectly search for physics beyond the Standard Model.  Several anomalies have been observed in the decays of B mesons, which have continued to persist with new data and have been explored as potential hints of new physics.  I will discuss a longstanding anomaly in the CP asymmetries of B decays to a kaon and pion, known as the K pi puzzle.  I will present a new measurement, the most precise to date, of the direct CP asymmetry in the decay B+ to K+ pi0 at LHCb. This measurement is consistent with the previous measurements of this quantity and significantly strengthens the anomaly.
