MH: White went up the g-file and played well, though not
perfectly. Black didn't ever finish developing and was not
able to defend the position with either passive defense or
counter-attack (there was none). In a Sicilian Defense Black
must play very aggressively on the queen-side because the
position is so cramped and passive elsewhere. Trying to defend
forever is usually a losing proposition. }

Hello Leopold,

Thanks?, ... and no more?

I think now is the moment for you to have a second deep look at the game
and say what are the points you agree from our analysis and what not.

I would like to know if you think you have learn something from the game
or from the comments you have seen (yours, Fritz, Me, Mark)

Sure that some moves were very difficult to find during tha game but
maybe during the game you were not afraid of some situations (open files
or something like that) and your feeling have changed now.
