My engine plays on FICS using a RaspberryPi B (256MiB of hash). Typical mid game search depths are 6-8 on the RaspberryPi. I also have some basic king shelter evaluation: when opponent has a queen it award pawns in front of the king.
This is one typical game it lost (taken from http://ficsgames.org/cgi-bin/show.cgi?ID=378951337)

I've seen the engine losing this way several times. King shelter is obliterated and a pawn is pushed to 6th rank defending a queen that traps the king.
What am I missing here? Is it lack of depth or some evaluation feature?

Re: help me analyze a game
That knight was tempting, this is common for most engines to fall on that trap not just your engine.
Probably you could raise your threat eval a little bit. It seems to me the issue is about attack and not about defense. From what I have observed, it is always better to make the engine feel the danger. But the problem was the engine was offered by a material, it is probably beyond the engine's ability to refuse that knight. It is good to see the log of that game. If you look on some of those positions it is clear that the queen has a lot of attacked squares on black's king camp. When the h-file was opened, the engine should also consider the rook may join in in the attack. Did your engine has such an eval?

Re: help me analyze a game
By this position, the game is lost:

I suspect that the problem is king safety.
Just think of it as a player. The queen is right in your front yard.
Do you want to punch a hole in the king's cover right now?
