Depends partly on you. If you have good biceps genetics your arms may get enough stimulation from compound movements (especially curl-grip movements). Meanwhile, if your biceps aren't as resposive you may need some isolation work to see growth/improvement.

I'm a good example. My triceps are just genetically very strong, but without iso work, my biceps just plain suck.

do some isolation like ironman said if u put in the time u will get the results and for chin ups i think the underhand grip works the best for biceps
