Badly placed knight protecting weak square

[Henk]

In the second half of a game my knight was on b2 because it had to protect a strong enemy square. Otherwise black might have a knight or a bishop on c4. I don't know whether it would have been better to develop the knight on b2 because it looks like you play the game with a knight less.

Again ,a post without a diagram or an exemple game mean nothing .

It's about general rule. I am not interested in one position.

So question is what is worse a badly placed knight (protecting weak square) or an enemy outpost.

Don't think piece square table catches long term effects. A badly placed knight for a move or three may not be harmful but if it stays there all the time. Maybe comparable to a trapped knight.
