At Checkmate Live, we believe that every millisecond matters. In the high-stakes world of competitive chess, a fraction of a second can mean the difference between victory and defeat—between executing your carefully planned strategy and watching your position crumble due to lag.
⚡ Our development team has been running at full throttle to revolutionize how online chess handles network latency. Working around the clock, they've tackled the edge server routing errors that affected some players last year, developing our groundbreaking Pro Lag Compensator system and unlocking 3,200+ edge nodes to fight Lag.
🧪 As we continue in this alpha phase, your feedback is especially valuable in helping us refine and perfect our technology. Despite our extensive testing, we know that all the testing in the world can't reveal every edge case until real players encounter them in the wild. This change log represents months of relentless innovation, endless testing sessions with players across continents, and countless cups of coffee as our team pushed to deliver what we believe is the most responsive, fair chess experience possible online.
The results speak for themselves: zero time loss for players with up to 300ms ping, server-authoritative timing that preserves competitive integrity, and a foundation for exciting new features that are now possible with our edge nodes operating at full capacity.
To our players: thank you for your patience and feedback as we've worked to get this right. The knight's move of innovation isn't always straightforward, but with each challenge, we're building something truly special. Let's play! ♟️

At Checkmate Live, we're addressing one of the biggest challenges in online chess—network latency—with our revolutionary lag compensation technology. We've heard your feedback from last year and have made significant improvements to ensure every player experiences fair, responsive gameplay, regardless of location.
✅ Move Registration Guarantee – Compensates for network delays up to 300ms ✅ Server-Authoritative Clock – Maintains true competitive timing without adjustments ✅ Competitive Integrity – Prevents manipulation possible with adjustable time banks ✅ Dynamic Calculation – Algorithm dynamically calculates time compensation based on user latency ✅ Zero Time Loss – Users with 300ms ping now experience 0.0s time loss per move ✅ Fair Compensation – Provides up to 300ms compensation per move ✅ Tested Globally – Successfully deployed with tournaments with players across India, Philippines, Poland, and other regions
At Checkmate Live, we don't fiddle with your clock to cover up lag. Every move is recorded fairly while keeping the game clock honest.
For casual games, we're developing a "lag bank" system similar to what other platforms use, but enhanced to prevent abuse. This will not be used in pro tournaments—rated and competitive games will always follow our strict server-authoritative time rules.
✅ 3,200 Nodes Worldwide – Deployed through Tencent EdgeOne for ultra-low latency ✅ Dynamic Activation – Edge servers activate based on player density, improving responsiveness over time ✅ Continuous Improvement – As more players join from a region, latency further improves through real-time optimizations
Despite our best efforts (and the wizardry of our tech team), there are moments when we find ourselves scratching our heads, wondering why a glitch appeared or a lag spike snuck through.
💡 Why does this happen?
Online chess is moving into uncharted territory—traditional platforms haven’t tackled real-time lag compensation or edge computing at this level before.
Internet infrastructure varies wildly by region—even with 3,200+ edge nodes, some weird ISP routing quirks can cause unexpected hiccups.
We’re bringing esports-grade tech to chess, which means there’s no playbook—we’re writing it as we go!
We hit a major challenge that had everyone scratching their heads—our team, our engineers, and even the brilliant minds at Tencent Cloud. A handful of players reported severe performance issues, forcing us to take a deeper dive into our infrastructure—and we’re actually grateful they did.
Our initial edge server deployment had a few critical configuration issues: ❌ Routing inefficiencies – Some nodes didn’t distribute workloads efficiently across the global network. ❌ Network traffic detours – Instead of direct routing, some packets took unnecessary detours, causing frustrating latency. ❌ Move registration delays – Lag was identified in the WebSocket event implementation, especially for pawn moves. ❌ Unexpected lag & crashes – Some players experienced major slowdowns that disrupted gameplay.
We didn’t just acknowledge the problem—we attacked it head-on. Those initial performance hiccups became a blessing in disguise, pushing us to develop the Pro Lag Compensator, a system designed to not only fix current issues but future-proof our platform.
🔹 Full audit of infrastructure to identify and resolve bottlenecks. 🔹 Reconfigured our global network for faster and more efficient routing. 🔹 Deployed the Pro Lag Compensator system to stabilize move registration across all time controls. 🔹 Completely rewrote & optimized WebSocket logic, reducing move lag significantly. 🔹 Expanded tournament testing with players India, Philippines, Poland, and more, ensuring optimisations worked with players from multiple regions. 🔹 Implemented enhanced real-time monitoring to detect and prevent similar issues instantly.
To further optimize our infrastructure, we brought in a new CloudOps lead with deep expertise in edge computing for online gaming. This ensured that we didn’t just fix our platform—we future-proofed it.
🚀 We’re the only chess platform applying cutting-edge edge computing techniques specifically designed for the demands of real-time competitive chess.
Now that our edge infrastructure is at full capacity, we’re ready to unlock new features that were previously impossible. Our team is about to throttle up and push the boundaries of what’s possible in online chess.
To the players who helped us uncover these challenges, to our partners at Tencent Cloud who collaborated tirelessly, and to our incredible development team who worked around the clock to solve these issues—thank you. Your dedication, expertise, and relentless problem-solving made Checkmate Live stronger than ever.
✅ No more move delays – Lag reduced significantly for all time controls. ✅ Ultra-low latency games – Enjoy instant move processing on a global edge network. ✅ More reliable matches – If a server has issues, another takes over seamlessly. ✅ Esports-grade tech in chess – Bringing competitive integrity & real-time fairness to online chess. ✅ No timebank manipulation – We don’t tweak your clock to hide lag—we fix it at the core.
We embrace them as opportunities to learn, improve, and keep pushing the boundaries of online chess. After all, innovation isn’t always a straight line—it’s more like a knight’s move! ♞
Now that our edge server infrastructure is fully operational and the Pro Lag Compensator is delivering results, we're excited to begin rolling out additional features that leverage this powerful foundation:
Enhanced Analysis Tools that utilize edge computing power for faster, more detailed game evaluation
Advanced Anti-Cheat Systems that operate at the network edge for more effective detection
Improved Tournament Management with better scaling for large global events
Expanded Global Coverage as we continue to optimize our network presence
These capabilities were always part of our vision, but required our edge computing infrastructure to be operating at full capacity. With the successful deployment and testing of our global node network, we can now begin throttling up these advanced features.
We embrace these challenges as opportunities to learn and improve. After all, innovation isn't always a straight line—it's more like a knight's move! ♞

Deployment Advisory
🔹 Server Updates & Transitions: When new updates or deployments occur, old nodes are purged and replaced with updated ones. During this transition, you may experience slightly higher latency until the new servers are fully warmed up and optimize.
🔹 Major Deployment Effects: For major deployments, the system requires time to propagate updates across all edge nodes. This means temporary increases in latency as servers synchronise and stabilise. Deployment durations can vary based on factors such as the nature of the update, network conditions, and regional considerations.
🔹 Dynamic Optimisation: As more players come online in your region, initial latency may be higher at first. However, as more users join, edge servers dynamically optimize routing, improving responsiveness and reducing latency over time.
🔹 Deployment Schedule Update:
Starting soon, deployments will be shifted to Tuesdays (CET).
This change aims to reduce disruptions during peak weekend play and allow for better monitoring post-deployment.
🔹 Tournament Readiness:
Nodes will be warmed up ahead of major tournaments to ensure optimal performance.
This proactive approach minimises potential latency spikes and ensures a stable gaming experience during critical matches.
🔹 High Latency Support & Optimisation:
Our system automatically optimises routing to provide the lowest possible latency.
In some cases, we can further optimise your location for better performance.
If you are experiencing a latency indicator above 300ms, please send us a screenshot via chat.
Include your latency measurement, city, and country, so we can analyse and work towards optimising your experience.
Alex, our new Asia and Oceania CloudOps lead who joined in Jan, brings expertise from Age of Ascent, a cutting-edge MMO that pioneered large-scale real-time edge computing.
His insights are helping us refine:
Edge routing & server selection to reduce lag further
Scaling infrastructure to handle large-scale global tournaments
Real-time anti-cheat & move synchronisation at the edge
AI inference at the Edge
