Multi-piece solid golf ball

A multi-piece solid golf ball comprising a core, a surrounding layer, an intermediate layer, and a cover, wherein a large number of dimples are formed on an outside surface of the cover, the core is formed of a single layer or a plurality of layers of a rubber composition, the surrounding layer is formed of a single layer or a plurality of layers of a resin composition, the intermediate layer and the cover are both formed of a single layer of a resin composition, and a relationship between an initial velocity of an intermediate layer-encased sphere and an initial velocity of the ball satisfies the following condition:

• (initial velocity of ball)<(initial velocity of intermediate layer-encased sphere), and
• where a deflection when the ball is compressed under a final load of 1,275 N (130 kgf) from an initial load of 98 N (10 kgf) is not more than 3.0 mm, a ratio CL1/CD1 of a lift coefficient CL1 at a Reynolds number of 218,000 and a spin rate of 2,800 rpm to a drag coefficient CD1 is denoted by A1, a ratio CL2/CD2 of a lift coefficient CL2 at a Reynolds number of 184,000 and a spin rate of 2,900 rpm to a drag coefficient CD2 is denoted by A2, and a ratio CL3/CD3 of a lift coefficient CL3 at a Reynolds number of 158,000 and a spin rate of 3,100 rpm to a drag coefficient CD3 is denoted by A3, the following two conditions are satisfied:
