Defining your hand: is it ever a good idea?

[Ben86]

i always say no and try not to do this but im starting to believe that sometimes it just saves chips.
For example:

I flat a button raise with J [img]/images/graemlins/spade.gif[/img]T [img]/images/graemlins/spade.gif[/img] lets say 60bbs deep.


Flop A [img]/images/graemlins/heart.gif[/img]J [img]/images/graemlins/club.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]

check call 2/3 pot.

Turn: 2 [img]/images/graemlins/diamond.gif[/img]

Leading the turn or flop, even though its not really for value or as a bluff makes the hand so much easier to play that im starting to believe maybe its okay.
