LiGround Crashing With Big PGN Files? Here's The Fix!

Hey there, fellow chess enthusiasts and data explorers! Have you ever been deep into your LiGround analysis, maybe trying to import a massive collection of PGN files—say, all of Abdusattorov's brilliant matches—only to be met with a frustrating freeze or, even worse, a complete crash? You're definitely not alone in this boat. The LiGround PGN import crash is a known headache for many, especially when dealing with those hefty PGN archives that are invaluable for ml-research and deep strategic study. It can feel like you've hit a digital roadblock just when you're about to uncover some fascinating insights or prepare for your next big game. This isn't just an inconvenience; it can severely disrupt your workflow and prevent you from leveraging the full power of tools like LiGround for serious chess analysis. But don't worry, we're here to break down exactly why this happens and, more importantly, what can be done to fix it, ensuring your LiGround experience is smooth, stable, and ready for all your big data needs. We'll explore the technical nitty-gritty behind these crashes, delve into practical solutions, and even offer some immediate tips for you, the user, to navigate this challenge until long-term fixes are in place. Let's get to the bottom of this frustrating issue and pave the way for a more robust and reliable LiGround.

Understanding the LiGround PGN Import Crash

The dreaded LiGround PGN import crash often arises when the application attempts to process large PGN files, like comprehensive player archives or extensive tournament collections. The core of the problem lies in how LiGround currently handles these imports. Specifically, every single game within the PGN file is parsed immediately and, crucially, on the UI thread. Think of the UI thread as the main highway for all visual elements and user interactions in an application. When a heavy, computationally intensive task like parsing hundreds or thousands of chess games is thrown onto this highway, it gets congested, causing everything else to grind to a halt. This synchronous parsing via ffish.readGamePGN is the primary culprit. It means that while your computer is busy interpreting every single move, variant, and piece position from a massive PGN file, your LiGround interface becomes unresponsive. You can't click anything, scroll, or even move the window. It's effectively frozen until the parsing is complete, or, as is often the case with very large or messy PGNs, it simply gives up and crashes.

Adding to this challenge, many PGN files, especially those collected from diverse sources, aren't always perfectly formatted. They might contain bad SAN (Standard Algebraic Notation), be missing critical Variant or FEN (Forsyth-Edwards Notation) tags, or have other subtle errors. When ffish.readGamePGN encounters these imperfections during its synchronous parsing, it doesn't just politely skip them or flag them for later review. Instead, it often throws an
