Subject: queen eval in early middlegame

Hi,

the following is a position I found in one of Sunsetter's search tree leef
nodes.

[D]r2qkb1r/ppp1pppp/2n5/4pb2/Q1P5/N7/PP3PPP/R1B1KBNR w KQkq - 0 9


Of course it sees that black is lost, but due to the eval() still being bad
beyond reason, even though I spend a couple of days on it now, it doesnt see
that its already 1-0.

One of the reasons for that is that it thinks the Qa4 of white is worse than the
Qd8 of black, which is of course absurd. White queen is active, can not be
attacked. Black queen is passive, and doesnt know where to go after Rd1 soon.
Right now I just use a piece square table for the queen with some big penalties
to avoid it move around with the queen too much in early opening.

How does one achieve both ?
- avoid too much queen movement in the early middlegame
- not make it think the white queen here is bad
