How good a bluff does it have to be to be believed?

[Mike_25]

A bluff ain't worth its weight in cow chips unless it's colder than a well digger's armpit and holds up better than a banker's vault. Them good bluffs is hard as nails, got more grit than a mule, and stand firm as a stone wall in a hailstorm. Don't matter how many chips ya got, a weak bluff's gonna get called faster than a cowpoke can finish his whiskey.

A successful bluff makes yer opponents as nervous as a whore in church, unsure if ya really got the goods to back it up or if yer just bluffin' like a chain smokin' poker shark. Keep 'em doubting and squirming on the hook, not with big talk but by holding yer cards close and watching for any tell. Mistakes and hesitance give away a weak hand, so keep them guessing right up until the last card's dealt. That's the sweet science of a successful bluff, partner!

The answer to this question depends on a number of factors, including the skill level of your opponent, the size of the pot, and the strength of your hand. However, in general, a bluff is more likely to be believed if it is: Well-timed. Bluffing when your opponent is likely to be on tilt or making a mistake is more likely to be successful. Based on a realistic range of hands. If you are only ever bluffing with the nuts, your opponent will quickly catch on.
