Player Search & Preparation

Player profiles, game sources, rating history, and opponent preparation

The Player tab lets you look up any chess player, explore their career statistics, browse their games across multiple platforms, and prepare against opponents. Open a Player tab from Player Base on the Home screen or from the sidebar.

Searching for Players

Type a player's name into the search bar at the top. Results autocomplete against the FIDE database, showing each player's name, title (GM, IM, FM, etc.), country flag, rating, and birth year. Use / to navigate suggestions and Enter to select.

Your last 5 searches are saved and shown when you focus the search bar, so you can quickly return to players you've looked up before.

Top Players & Rankings

Before selecting a player, the tab shows world rankings by category: Standard, Rapid, Blitz, U18, and Women. You can toggle between Live and FIDE ratings. Scroll down or click Load More to see more players.

An Advanced Search option lets you filter by country, title, sex, active status, rating ranges, birth year, and sort order — useful for finding players who match specific criteria.

Player Card

When you select a player, a profile card appears on the left showing:

Info Tab

The Info tab gives you a quick overview of a player's career and style.

Opening Repertoire

Shows the player's top 10 openings as White and top 10 as Black. Each row displays the ECO code, opening name, number of games played, and their win/draw/loss record. Click any opening to jump to the Games tab filtered by that opening and color.

Career Activity

A summary of the player's career statistics: total games, games per year, first and last game dates, years active, best year (by game count), average game length in moves, and shortest win.

Progress Tab

The Progress tab tracks how a player's ratings have changed over time.

Rating History Chart

An interactive line chart with separate lines for Standard (blue), Rapid (green), and Blitz (orange). The chart auto-scales to fit the data range. Hover over any point to see exact ratings on that date.

Monthly Breakdown

A table showing month-by-month ratings for all three time controls with color-coded deltas — green for gains, red for losses — and the number of games played each month. Displayed in reverse chronological order (newest first).

Performance by Color & Time Control

Donut charts showing win/draw/loss percentages broken down by color (Overall, White, Black) and by time control (Classical, Rapid, Blitz).

Records Tab

The Records tab highlights notable games and opponent statistics.

Best Wins & Worst Losses

Side-by-side tables showing the player's top 8 wins against the highest-rated opponents and top 8 losses against the lowest-rated opponents. Each row shows the opponent name, their rating, piece color, and date. Click any row to open the full game.

Opponent Analysis

Events

Two sortable tables: Top Events (most frequently played) and Best Events (highest performance). Both can be sorted by event name, score percentage, performance rating, or game count.

Games Tab

The Games tab lets you browse a player's games from multiple sources, each with its own set of filters.

Game Sources

Four source modes are available as tabs at the top:

SourceFilters
FIDEFull filter set — color, date range, time control, opponent, result, ECO opening, variant, ELO ranges, event, site, exclude online
Chess.comColor, date range (requires Chess.com username)
LichessColor, date range (requires Lichess username)
CombinedAdd multiple sources dynamically, each with independent filters. Mix FIDE players, Chess.com users, and Lichess users in one view

Browsing & Previewing Games

Games appear in a scrollable table with columns for date, players, result, ECO code, event, and time control. Click a game to preview it in a side panel with a board and move list — use / to step through moves and Home/End to jump to the start or end.

Double-click a game to open it in a new board tab for full analysis. You can also drag a game row onto the sidebar to open it.

Opponent Preparation

Preparation mode lets you study an opponent's opening repertoire before a game. Here's how to use it:

  1. Select the player you want to prepare against.
  2. Go to the Games tab and configure your filters — most importantly, set the color your opponent will play and optionally narrow by time control or date range.
  3. Click the Prepare button.
  4. A new board tab opens with the opponent's opening repertoire displayed as a variation tree, showing their main lines and key deviations based on the filtered games.

The preparation tab is named after the player with icons indicating the color and time controls — for example, "Kasparov ⚪ ⌛🕗" means White games in Classical and Rapid.

In Combined mode, you can prepare against multiple players or accounts at once — useful if your opponent plays on multiple platforms, or if you want to study a group of players who share a similar repertoire.

Tips:
  • Click an opening in the Info tab to quickly jump to filtered games for that opening.
  • Use the Combined source to merge a player's FIDE, Chess.com, and Lichess games into one preparation tree.
  • Click any game in the Best Wins or Worst Losses tables to open it directly — great for studying critical moments in a player's career.
  • The player URL updates as you navigate (e.g. /player/1503014), so you can bookmark or share links to specific players.
