Personally, checking to me twice is like pushing a button: bam: I bet!

My own percentage is probably around 70%. I'll rarely make the bet against more than two players though.
Weary as I am of traps, I know a trappable prey when I see one. Few things in poker are as enjoyable as flopping the nut Boat, min betting or checking into the guy who owns a bam button, and repopping.
In general though a reasonable bet will usually take the double checked hand down, but as said, you don't want to get predictable about it.
