Hi Robbie.
Just a few words about the notes.
Black has just played 10...c6
"a losing move, not solely because the Knight is trapped, but because the
c5 square will be weak for the entire game, this has much more significance
than winning the hapless knight."
I think most of us would consider the taking of the Knight more important
especially as the square c5 is not weak till Black's move 11...b5.
What you have (apart from being a whole piece up) is a potential weakness
at c6 after, and if, Black should play b6 to cover c5.
"look at this structure, its the stuff dreams are made of,
a weak c5 square and a backwards pawn on c6."
No mention of being a piece up. That is the stuff dreams are really made of.
It's easy being a piece up to carry out any strategical idea that takes
your notion. Your pieces cannot be challenged from going to good
squares because every exchange (a strategical aim when a piece up)
will take Black closer to a resignable position.
(it's close to that now.)
You write a good positional game, however...
Here you played 12.Bb3 holding the a-pawn.
Better, and in line with your thoughts of the weak c5 sqaure would have been
12.Qc1
Holding the a-pawn, spotting the c6 pawn and leaving the b3 square vacant for
(after castling) Nb3 hitting the Queen and Nc5 occupying the weak square with a Knight.
Later on you waste a tempo playing 18.Bb3-a2 to free b3 for the d2 Knight.
Spotting weak squares is easy, working out routes (usually via that dirty
word - 'tactics'😉 to exploit them is not so easy. Here you failed and that
can cleary be seen in 18.Ba2.
Really the whole game was blitz with little in it.
White was given a piece, Black dug in hoping to win on time.
No mention of 24.Bxe6+ here.
(You treated this Bishop pretty badly in this game.)
But we can get something from it:
Other pieces and pawns taking potential Knight squares.
First we learn not to place our pieces and pawns en prise.
We get better and learn not place our pieces and pawns where
they could block or hinder our other pawns and pieces.
This game showed a tactical example. 10...c6 blocking the Knights retreat
and a positional example 12.Bb3 requiring a later 18.Bb3-a2 and 21.Qc5-b4
to undo it.
