Well I dont know the exact position but you seem to be broadly correct. I could maybe think of the odd instances where it might be okay though, such as where the d file will be blocked by a bishop coming to d7 so Qa4 Bd7 Qb3 hitting the b and d pawns. Overall, yes it is worth far more than the knight and is more vulnerable but if you can't use it when you need to use something then it's not worth 9 points.

Thank you for the input plenty.
I did an infinite analysis on fritz and d6 is definitely preferable. Qa5 appears to give white at least a +1.00 score.
Thanks, now I know that I am not a complete idiot to disagree with the computer analysis I get. That is comforting.
Ahh wait, having seen the position I realise. You are using chess.com computer analysis. That thing sucks. I think it gets slightly better for each level of membership you take on but I still haven't heard any good things about it. Trust my cat before I would trust that thing. I don't actually have any chess programs unless you count xbox chess so was quite pleased to use it at first...then it hit me how awful its thoughts were.
While in this case we are all right, the queen check is very useful in the accepted lines I might add. And Plenty, I am very interested in hearing your cats opinion on the matter :).
Note I usually play the old benoni defense and go into the benko but I gave the modern transposition
This was not a pin, but it still shows the conceptual exception to what we were discussing within the same opening
I keep getting my game analysis back with suggestions to use my queen to pin a knight (benko gambit declined if you need specifics) in the early game. I am not as strong as the computer doing the analysis I know but I always thought such a move was weak unless the corresponding bishop was already gone, or an immediate and decisive follow up attack was operable. My reasoning was that the bishop in most situations will instantly destroy the pin and leave your queen forced to move again to protect from discovered attack thus putting you down a tempo (unless the attack I was talking of is available) and also usually with your queen on the side of the board with minimized effectiveness. Thoughts?
