I guess the difference in opinions comes down to semantics of definitions. Obviously not all bets that are +EV are value bets...that's not what I'm saying.

You define a value bet as a bet where we have more than 50% equity vs a calling range. In one book I've read the author defines a value bet as a bet to get worse hands to call and a bluff as a bet to get better hands to fold (and he plays high stakes btw). Which definition is correct? I'm not really sure.

What exactly are we trying to do when betting a T? With a T he never folds better hands, but he does call with worse hands. By the definition I've read that would make it a value bet and not a bluff. You want to call that a bluff? I'd argue that's more like a thin value bet. You could also argue that its a bet to collect dead money, which would be neither a value bet or a bluff.
