My favourite is Ng5 but Ne5/Be4 also seem heavily advantageous to white. And to drive the point home even 15. Rb5 might lead to a better game for white even if he might have to retreat with the rook later. A funny albeit not forced line with a double rook sacrifice: 15. Rb5 cxb5 16. Bxb5+ Kd8 17. Ne5 Qb2 18. Nxf7+ Kc8 19. Qd3 Qxa1+ 20. Kh2 So while nice the move IMO seems to be one of many in a position black has wasted beyond repair.
