NL50 - why is "bet/call, bet" a bad line?

[Khumalo]

The thing with a "bet/call, bet" line is that it typically signals a lot of strength, and should be applied judiciously, in my opinion.

In hand one, villain, who's not too aggro, attacks your c-bet on a very dry board. If you're somehow ahead, and he's running a rare bluff, or testing his TT-88 (which is way behind), your turn lead often shuts down that entire part of his range, when other lines might not. This means he can't easily continue putting money in with a worse hand, and if he has you beat, you're building the pot for him OOP.

Against another opponent, say a maniac who wants to felt any J because it's (omg!) top pair, 'bet/call, bet' can be a variation on 5-betting the flop all-in or whatever, especially on a dry board.

You can also use 'bet/call, bet' to manipulate thinking opponents who might have some history with you. A turn lead might freeze up some of them and get you to showdown more easily. It might look bluffy/weird to others and unexpectedly net you more action from a wider range.

Against fish, it might be good against a certain breed who make generic type raises with all their (say) flush draws, will fold to a flop 3 bet, but will keep paying a lot to chase in position when the turn blanks. This scenario is a little precise, so your 'bet/call, bet' line needs to be backed by reads.

In a total vaccuum, the problem with 'bet/call, bet' for value is that it tends to fold worse hands, prevents bluffs you could pick off with a check-call, loses value versus aggro droolers you ought to be CRing all-in on the turn (although the latter case is debatable.)

Using it to bluff or block bet is a murkier matter, and requires insight into villain, plus an overall style of play that harmonizes well with such a move, plus some kind of history.
