Introduction

In 2020, in the midst of the pandemic, I reconnected with an old passion: chess. The ‘Queen’s Gambit’ series on Netflix wasn’t just entertainment; it was a trip down memory lane, evoking those intense board battles from my younger days. Since my return to the game, I’ve been consistent but not without challenges, particularly with my rankings. Despite investing time in studying chess techniques (Highly recommend GMNaroditsky’s YouTube channel) over recent months, hitting ranking plateaus became frustratingly routine. That’s when I decided to combine this renewed passion with my profession of data analytics. This analysis aims to delve deeper into my gameplay, highlighting areas for improvement and charting my progress.

The Data Collection Process
For those interested in the details, the deep analysis in this project comes from a carefully put-together data-gathering process. Drawing data from Lichess and Chess.com, I employed Python, API calls, and some data wrangling to weave together a coherent dataset. Detailed insights into this process, alongside code snippets and challenges faced, can be explored on my GitHub page.

Recent Trends Indicate Triumphs

An encouraging aspect of this analysis is the recent trends. When comparing August to July on a Month-over-Month basis, I’ve noticed significant strides in every category.

MoM comparison

Volume of Games: In August, I ramped up my gameplay, competing in 67 matches. This represents a staggering 179% increase compared to July.

Win Rate: My dedication to the game is clearly paying off. Out of the 67 games played in August, I secured victories in 56.72% of them. This is an impressive uplift of 23.74% in my win rate from the previous month.

Elo Rating: All these positive trends culminate in the ultimate metric for every chess player: the Elo rating. My rating peaked at 1842 in August, marking a 2.24% improvement.

These positive trends correlate with the increased time I’ve devoted to the game. Whether it’s watching instructive chess videos on YouTube, meticulously analyzing my games, or simply playing more, the extra effort is evident in the results.

Yet, even with this progress, I believe there’s always room to further refine one’s game. And this is where deep data insights come into play.

Discovering Insights from Data

A dive into the data revealed intriguing patterns and insights about my gameplay.

Interesting statistics to note out

Day-wise Performance: One of the first surprises came from my performance stats across different days of the week. On Tuesdays, I seem to be on fire with a win rate of nearly 60%. However, Thursdays tell a different tale, with my win rate plummeting to under 40%. Living in Israel, Thursday marks the end of the workweek. Perhaps it’s the weight of the work week catching up? A bit of mental fatigue creeping in? Or maybe Thursdays are just my ‘resting rook’ days, where my king needs a breather! Whatever the reason, it’s a pattern I’ll be mindful of in the future.

Win Rate by Opening with White

Opening Moves as White: When I play white, my signature move is e4. Against opponents who choose the Sicilian defense, I boast a win rate of 56.52% — a notable 4% increase over my typical 52.44% win rate. The Sicilian defense, characterized by its initial move 1.e4 c5, is one of the most popular and aggressive defenses against the e4 opening in chess. It’s known for its complex nature, offering a multitude of variations that can quickly lead to an unfavorable position for the unprepared player. Having played the Sicilian as black in my past games, I’ve managed to sidestep many of its pitfalls, often turning the tables to put my opponents on the defensive right from the opening.

However, it’s not all rosy. My Achilles’ heel appears to be against the French defense and the Scandinavian defense, with win rates of 44.44% and 41.67% respectively. Upon reflection, a key commonality between these two defenses is their tendency to lead to asymmetrical pawn structures. This characteristic can present strategic challenges that might not align with my usual gameplay style.

For instance, such asymmetrical positions often involve more nuanced planning, pawn breaks, and endgame intricacies. If one is more accustomed to symmetrical structures or more straightforward plans, these positions can become difficult to navigate optimally. It’s possible that the inherent complexities of these structures and the different strategic themes they evoke are areas I’m currently less comfortable with.

To turn the tide in my favor, a more granular exploration of the typical pawn structures and plans in these openings might be the key. This would ensure I maintain my advantage and don’t fall into common traps or misconceptions associated with these defenses.

Win Rate by Opening with Black

Opening Moves as Black: With black, I’ve held a preference for the Caro-Kann defense. However, the numbers were a bit unexpected: my win rate with this opening is a mere 43%, notably lower than my overall average of 48.33% as black. Reflecting on this, I wonder if there’s a combination of factors at play. Is it certain specific variations within the Caro-Kann that trip me up, or perhaps the generally defensive nature of the opening that doesn’t mesh well with my more aggressive gameplay?

Additionally, the Caro-Kann has recently surged in popularity, thanks in part to coverage from prominent chess YouTubers. This likely means that players around my level have become particularly well-prepared to counter this opening. The playing field might be more challenging due to opponents being better versed in its intricacies.

A deeper analysis of the specific variations I encounter will undoubtedly shed light on these challenges. In the meantime, I’ve been experimenting with the King’s Indian defense as an alternative opening choice. I’m intrigued to explore its impact on my performance and plan to monitor its effectiveness as I further navigate the complex world of chess.

Future Endeavors: Deep Dives and Expanding Horizons

As I reflect upon my journey with this project, it’s apparent that there’s still so much more to uncover. Chess, being a game of complex strategies and multiple layers, deserves an analytic approach that can capture its depth.

Opening Analysis Overhaul: One extension in the works is a second tab in the dashboard dedicated solely to analyzing chess openings. While the initial analyses provided insight into my performance against specific openings, I believe a more granular approach is necessary. This new dashboard will enable users to:

  • Drill Down into Variations: No two games are the same, and while overarching opening strategies can be identified, the devil (or in this case, the winning move) often lies in the details. This feature will allow me or any user to explore specific variations of openings, offering insights into which particular lines work best for or against me.
  • Win Rate Contextualization: Raw win rates provide a good starting point, but context is king. The enhanced dashboard will juxtapose my win rate against the average ratings of my opponents. This feature can provide clarity on whether I’m genuinely mastering an opening or if certain successes are skewed due to facing weaker opponents.
  • Time Period Filtering: The landscape of chess, much like any sport or game, evolves. New strategies emerge, old ones get refined, and player behaviors shift. To stay current and relevant, the dashboard will incorporate a time filter, enabling me to understand how my performance varies across different periods. This will help identify if any recent changes in my game strategy are yielding positive results or if they need rethinking.

In essence, this upcoming phase of the project aims to bridge the gap between general insights and detailed analysis. By honing in on the specifics, I believe I’ll be better positioned to identify improvement areas and craft a more informed game strategy. Plus, it will undoubtedly be a valuable tool for other chess enthusiasts who are as data-driven in their approach to the game as I am.

Conclusion

As I step back and assess this intricate dance between chess and data analytics, a few pivotal revelations emerge:

  • My rekindled passion for chess, sparked by the evocative “Queen’s Gambit,” prompted not just consistent gameplay but an analytical journey to refine my strategies.
  • Recent trends have been promising. The month of August showcased a significant surge across all key metrics: games played, win rates, and overall rating. This speaks volumes about the benefits of dedicated learning and consistent practice.
  • Delving into the specifics, certain patterns and opportunities for growth were apparent. Tuesdays proved to be my best performing day, while Thursdays… well, they might just be a testament to the weariness of a workweek in Israel! Opening-wise, while my offensive against the Sicilian Defense seems solid, there’s room for improvement against the French and Scandinavian Defenses. And my preferred Caro-Kann with black? Perhaps it’s time for a strategic rethink or deeper exploration into its variants.
  • The journey doesn’t end here. Plans are already underway to amplify the analytical depth, with a dedicated dashboard targeting openings and their nuanced variations.

In conclusion, this project encapsulates more than just a statistical overview of my chess performance; it’s a testament to the power of merging passion with data. Chess, with its myriad complexities, paired with the precision of analytics, offers a roadmap to continuous improvement. As the pawns and pieces move across the board, and data points shift across the dashboard, the quest for mastery persists.
