Homer vs JTG, checkraise turn hoping better overcards fold.

[kiddo]

In a very good post recently (Homer: 05/12/03 10:51 AM) a player, JTG, was raising on the button with KK. Homer 3-bet in small blind with KQo. JTG called, going for a raise on turn. Headsup on flop.
FLOP: 457r
Homer bet, JTG called.
TURN 457(6)
Homer check, JTG bet. Homer checkraise, hoping JTG would fold better overcards.

Im to weak to do this checkraise on turn to get overcards to fold. But Im trying to learn.

My questions are: How often do you do this? Is this routine for Homer, or is it a tricky move against a player he knows well? Would you do it against an unknown opponent? Which flops, turncards are good for this?
