Assuming you're delaying and not doing some other method of holding your initiative, you actually push your initiative count to the new value for the rest of the combat.  So if you delayed until after the orcs moved, then you won't get a turn again until after the orcs take their turn again.<br/><br/>http://www.d20pfsrd.com/gamemastering/combat#TOC-Delay (http://www.d20pfsrd.com/gamemastering/combat#TOC-Delay)
