This is a game vs a 1566 in the Traditional variation of the QGD which happens to be my favorite opening of all time.
There is one very important idea Black didn’t play to strengthen their structure which cost them the game. Black needs to play c6 in order to defend d5 in the center and then play the knight to d7.
It’s Black move, the position is equal and Black only has one real weakness which is the pawn on d5. Black needs to play c6 to bolster the d pawn, if you notice once I castle the knight on c3 threatens to capture the pawn and fork the Queen and bishop in the process.
Black does eventually defend the pawn but with the Rook instead. The fact that their bishop captured my knight allowed me to attack the d pawn twice once the King castled. There was a line to partially defend with Ne7 which I look at in the analysis. From this point Black goes down a pawn, recaptures their bishop with the Queen and I capture the knight on c6 with my bishop stacking their c pawns. We get the position below where Black is down a pawn and the Queen side structure is a wreck.
Objectively the position is lost here, even with proper defense Black has too many pawn weaknesses I could exploit while stretching their defenses too thin. The game becomes a matter of technique and clean up from here. The opening had some theory and I analysis quite a few possible lines for the future on lichess.
This was a 3minute blitz game in the Caro vs a 1500 opponent. I’ve talked about the idea of taking advantage of the c file in the Caro before and this game is another good example of how mounting pressure leads to failures. The opening is nothing spectacular, both sides play reasonably well and it leads to a balanced position til the 15th move.
Another notable take away from this game besides the c file is the choice of White’s to play Bd3 instead of Be2 or Bb5, this usually gives Black some ease of development as the light bishop tends to be weak.
Lets go through some of the main positions of the game and analyze them. Below we see White’s choice of Bd3, the natural move for Black is to capture on d3 and White recaptures with the Queen. Black has removed a potentially weak piece while White gets the Queen off the back rank which may or may not be helpful.
Below we get to another position where White choices the wrong capture and enables me to move forward with my plan earlier. White should have captured the knight on d7 forcing the recapture with my Queen. By taking the C6 knight my rook can capture and on the next move I’m in place to double on the c file which was the plan the entire time.
I expand on the Queen side and look to get the knight into c4, another common idea and more so when White pushes b4. In this case by pushing b4 White has left the knight defended by the Queen and rook, Rxc3 will simply win the game on the spot which I play and the game cleans up nicely in the next 10 moves.
