a and b connect the black stones by attaching to a weak stone, . As such they are defensive. For example, b offers white a ponnuki in the center in exchange for security.
c moves out sturdily with the most powerful immediate threat to enclose . This limits white's tactical options.
d moves out faster as part of a more flexible attack. However, black may be plagued by the possibility of cutting the knight's move.

Considered in isolation, this lets white immediately take c and split black's position rather easily. However, e may have a threat to surround a nearby position, such as the 4-4 stone in a common joseki. Or, e may be sufficiently valuable in reducing white's sphere of influence to justify giving white the large gote reply at c. See also
