cause it happens I have an engine too, and I can easely see your main line is
the main line of all the engines I have tested, but I'm sire you have tested
your main line and all what could follow by the sidelines, that were not quoted,
by yourself...

could be, I guess you're not one: so how do you know?

I understand the position is bad, I guess you don't wat to listen: I simply said
may be it was an option to "admit black is worse and take the pawn", instead of
getting into a locked position and shuffling pieces with no plan.

>You said black can play Bd7 followed by Nc6. This is obviously wrong.

Again I said it was an option:

>It fails tactically.

it does not necessrely fail tactically, depends on white move, since I did no
make any assumption on white move how can you say it fails? You assume your main
line is the truth?

>Show me how you want to proceed after Re1.

Ok I admit on Re1 Bd7 does not work, but there are other options Be6, Bf5, Bg4,
h6 and others, I'm pretty sure now you can start your engine and show me white
is better.
There also other option to give a pawn inbetween and get a position one pawn
down not as bad as what fritz got in few moves. But we are in a to long story of
if and if

What you fail to understand is that your engine will continue to miss the key
point: Qc7 is bad as well and may be even worse

that's another point. The fact Fritz it does not understand why it did lost does
not make the loss less good.
