Fritz 13 after a depth of 18/50 still has this a 0.00

well this is definitely not a draw.

with Bh7+, Kf7 Qg6+ Kf8 Qxf5+ Ke7 Qxg5+ Kd6 Rh6+ (or Rd1+ winning the queen), Kc7 Qxe5, white pretty much takes all of black's pieces and it's an easy win. Not sure if there's mate or not, but there probably is.

The weakness of fritz 13. Evaluating the true score of a position. Often times its incredible and sometimes its just dumb. Fritz kept thinking the best move was repitition causing draw not to lose the queen. I lost easily.

Maybe you should upgrade the engine to something stronger;  Houdini 1.5 is a free download and I'm sure there are others.

I've tried houdini within fritz and its an excellent analytical engine. (Finds mate in like #25). Fritz would never do that. It seems to use all quad core cpus to the max and I felt I was better off just deleting the engine

You ask why does white play 9. Kh1.  This is usually a sign that white wants to push his f-pawn without the worry of having his king on the open g1-a7 diagonal.  If white plays 9. f4, then black has 9...Qb6 pinning the knight on d4.  It is interesting that it only went for a draw instead of the win.  

 I notice that now. Also I was wondering why Fritz opening book has 6 BD3 as a ?. I guess that would be for the same reason - the pinned knight on D4.

it is strange that Fritz 13 sees a draw I tried the same position in chessmaster XI and it finds a mate in 15. without modifying the engine.

I wonder why people think Frtiz is a better chess program than chessmaster

Fritz always evaluates repeating moves as a draw for some reason. If you go back to before white plays Bg6+, Fritz says white is winning easily.

my shredder 11 immediately marked the score as +10.11.  black is for sure lost here with best play.

Why is BD3 a poor move on move 6

because e is already protected, so the bishop becomes a big pawn.  better would have been Bc4 maybe, keeping it active.
