Chess.com's Counterintuitive Fix: Show Losers Their Brilliance
Chess.com discovered that 80% of players who used game review did so after wins — the opposite of what the team assumed. By redesigning the post-loss experience to highlight a player's best moves rather than their blunders, they grew game reviews by 25% and subscriptions by 20%, while also lifting retention. The lesson: human psychology often runs counter to product intuition, and a single insight about emotional state can ripple across an entire product.

The Assumption That Was Wrong
When Chess.com built its Game Review feature — a virtual coach that analyzes a completed game and teaches players about their best and worst moves — the team assumed players would lean on it most after losses. That's when you've made mistakes. That's when you'd want to learn.
The data told a completely different story.
Chess.com's PM Dylan, who owned the learning features, surfaced a striking finding during an exploratory sprint: 80% of players who reviewed their games did so after a win. Not a loss. A win. The feature built to help people learn from defeat was being used almost exclusively to relive victory.
The Psychological Tension
This mattered because losses are common — especially for Chess.com's large base of new players. Over 75% of new users describe themselves as complete beginners or novices. And beginners lose a lot: fewer than one in three win their very first game on the platform. Each loss stings, and the data confirmed it: losing a game leaves a player with retention that is 10% worse than if they had won.
The original post-loss Game Review experience compounded the pain. It surfaced blunders. It highlighted mistakes. It showed players, in painful detail, exactly where they'd gone wrong — precisely when they were least emotionally equipped to process that feedback constructively.
The feature was technically doing what it was built to do. But it was psychologically working against retention.
The Move
The team flipped the framing.
After a loss, instead of leading with blunders, Chess.com redesigned the post-game experience to surface a player's brilliant moves and best plays first. The virtual coach's tone shifted from analytical critique to something more like encouragement: Losing is just part of learning — keep it up.
The core game review data was still available; the change wasn't about hiding the truth. It was about sequencing the emotional journey. Meet the player where they are emotionally, give them something to feel good about, and then invite them to learn.
The Result
The impact was dramatic and fast. That single product change drove:
- Game reviews up 25%
- Subscriptions up 20%
- A meaningful lift in user retention (described as "a lot" by the team)
But Albert Cheng, Chess.com's VP of Growth, framed the outcome as more than just a win for one feature. The underlying insight — that users respond better to positive emotional framing after failure — was a piece of human psychology applicable across the entire product. The PM working on puzzles could now audit their feature for similar "cold patterns" and redesign them. The color of a button, a line of copy, the framing of a score — all of it could be reconsidered through the same lens.
The Lesson
Product teams often build features based on rational assumptions about user intent: People will want to review their mistakes so they can improve. But users are not optimizing for improvement in the abstract — they're optimizing for how they feel. The 80/20 split between post-win and post-loss reviews wasn't a data anomaly; it was a window into what motivates people to come back.
At Chess.com, the retention unlock wasn't a new feature, a new channel, or a new growth loop. It was a change in emotional tone at a moment of vulnerability. That's the kind of insight that doesn't show up in a roadmap brainstorm — it shows up when a PM goes looking for counterintuitive patterns in actual user behavior.
Challenge
Over 75% of Chess.com's new users are beginners; fewer than one-third win their first game, and losing a game leaves players with 10% worse retention than winning. The Game Review feature — built to help players learn from mistakes — was structurally reinforcing the pain of losing by surfacing blunders immediately after defeat.
Approach
Chess.com redesigned the post-loss game review experience to lead with the player's brilliant moves and best plays, rather than their blunders, and softened the coach's tone to be encouraging. The change resequenced the emotional journey without removing the analytical content.
Results
- Game reviews growth: +25%
- Subscriptions growth: +20%
- Retention delta: loss vs. win: 10% worse retention after a loss than a win
- New users who are beginners: 75%+
- Beginners who win their first game: less than 1 in 3
- Game reviews done after a win (pre-change): 80%
