i think the "someone" was talking about pole vector constraints - if you create a locator, position it behind the ik handle and then select then select the ik handle with the locator and go to constrain>pole vector you should then get the desired effect. (sketchy explanation but experiment and you'll getwhat I mean).
The differences between the SC and RP IK solvers are explained pretty well in the docs

in terms of solvers i no of 3: single chain (SC), rotate plane (RP) and IK spline

the single chain is for connecting joints of 2 bones usually, and its ur basic IK handle

the rotate plane is fun, its the same as the SC but gives you a pole vector control. so for example you have a bent elbow, the pole vector would allow you to control the direction the elbow points

the ik spline is for spines of characters (there are some rules you have to follow wen creatin ik splines tho). this solver use the CVs of a EP curve to move bones in the backbone
