Thanks. I missed the opportunity to win a piece with tempo even in going over
the game today. I still need work on ttactics. I still have some blind spots.
Thanks for replying. It is a real treat to hear back about my own games. Even
if it points out my own mistakes and missed opportunities.

OK, I have not spent any time looking at this in depth, nor have the time, but
white is simply better, if not positionally winning, before, 12... Bxc3?
The text-move is a very poor positional move, giving up the dark-squared bishop
for absolutely nothing at all. Black has so many other better moves and had to
keep this on the board, for control of some useful squares. Giving white the
bishop-pair is unforgivable. After this ill-advised exchange, white has total
control of the dark-squares. White has the centre and will eventually push
through in the centre. White has the better of it, and I would be disappointed
if white did not have a tremendous game in the middle-game, but after 12...
Bxc3, I would be very seriously annoyed if I did not beat black from there on.
12... Be7, 12... Ba5 or even 12... a5 are all perfectly acceptable moves for
black and should be played, without any doubt at all.
I have no clue at all what is going on on move 16. Bxf6 is a dreadful move too
and just loses tactically on the spot. Surprising that an attacking player did
not see the simple 16... bxc4 gaining tempo on the white queen. Black is just a
piece up and white should resign then. 16. Be3 keeps the advantage to white and
although it will take longer, white is still clearly better.
Of course, once white has foolishly taken on b5, then the game is simple enough
for black. The back-rank is always going to be weak and the a7-g1 diagonal will
be vulnerable to a check, forcing the white king into the corner. The back-rank
will be easy enough to collapse. That is not a complicated concept to see. As
soon as exchanges occurred on b5, the C-pawn becomes a target, which can be
undermined by b5-b4. I would know that tactics would be available for
back-rankers and have no doubt that black could win from there on.
White should not exchange on b5, but put his queen on b4 and seek queen
exchanges as much as possible.
Playing strange ideas like Rad1 and Rfe1 accomplish nothing at all for white.
After move 16, white went astray and never played a decent move thereafter.
OK, all said in a brief, brief glance.
Take it easy

See if you can figure out the move on which I first began envisioning and
plotting this sacrifice.
