Statistics

The statistics button in the toolbar, or View › Show statistics (⌘L), puts the statistics in place of the list; the same button, or View › Show games, takes you back to the games.

What counts is your games among those of the list: the list chosen in the sidebar, with the search there is. Your games are recognised by the profile, from the name, the FIDE ID or the aliases: without a profile the app cannot tell you from your opponents, and the statistics ask you to fill it in. That way the same statistics answer different questions: a collection, a year, the games at a slow time control, those against stronger players.

At the top, the line says which games are being talked about and how many there are; beside it, All, Over the board or Online applies to every chapter. There is no choice of colour: the cards that count White and Black show them both.

On the left, the seven chapters. The page scrolls all in one go, and the highlighted chapter follows the one you are reading; a click on a chapter takes you there. The numbers are written on the charts, and the pointer over a value says more.

Score %

Where it appears, Score % is (won + drawn/2) / (won + drawn + lost): games without a result do not count. The pointer over the title recalls the formula.

Portrait

• In brief: the clearest facts from the other chapters, one per line, without advice. Your Elo from the first time to today, the Score % with White and with Black and against players rated at least 100 points above you, the best performance in a tournament, the phase in which you play best and the one in which you play worst, how many won positions you then won, in how many games you got into time trouble. A line is there only when the games are enough to say it.
• Score %, Average length, Won, drawn, lost, Score % by colour.
• Your rating, by list: one row per list and time control, for example “FIDE · Standard”, with Today, from the profile, and from your games Latest (with the date), Lowest, Highest and Games. No average.
• Rating over time: a stepped line for each list and time control, four at most; the diamond at the end is your Elo today, from the profile, and the highest is written. The pointer gives Elo, date, opponent and tournament. Games without the full date stay out of the lines, and the card says how many there are.
• Score % by year, in columns: the value above, the decided games below; Games per year.

How they end

• How they end: how the games closed, from the Termination data.
• Results by colour: won, drawn and lost with White and with Black.
• How long they run: the games by length in moves, 1–20, 21–30, 31–40, 41–60 and 61 or more; over each column the games, under it their Score %. Below the chart, the shortest, the average and the longest.

Openings

• Openings with White and Openings with Black: each ECO code with all its variations, the most played first, written “code · name”; a click opens its variations. Each row has the games, won–drawn–lost and the Score %: green above your average, red below, and below the list the line “Green above your average (…), red below.”. The pointer says by how much.
• Above expectation and Below expectation: in each game the two Elo ratings say how many points you should score, according to FIDE’s table. Here the openings, with White and with Black, in which you scored more, gaining Elo, or less, losing it: first those with the biggest difference. Columns Games, Made, Expected and Difference. Only games with a result and both Elo ratings count, and every opening, even with a single game; those exactly as expected are counted under Above expectation.

Opponents

• Opponents: the ones you meet most.
• By opponent strength: the games split in three, against players rated at least 100 points above you, at least 100 below, and those in between. For each, won–drawn–lost and Score % with White and with Black, and overall the games, the Score %, the opponent’s average Elo and your accuracy. A game without the Elo of one of the two stays out.
• Average opponent: one row per list and time control, with the average, lowest and highest Elo of the opponents and the games; two different lists never end up in the same average.
• Who you meet: year by year, a table per list and time control, with the games, the opponents’ average Elo, your average Elo and the Score %.

Tournaments

A tournament is an event whose games have a round: a tournament over the board or an online Swiss does, casual games or online arenas do not.

• Your tournaments, the most recent first: for each one a token per game (1, ½, 0), the points (4½/7) and the performance, calculated as FIDE does: the average Elo of the opponents with an Elo plus the difference FIDE’s table gives to the percentage scored. A click on a tournament shows it round by round.
• Round by round, beside it: round, opponent, Elo, colour and result of the chosen tournament. Show in the list puts its games in the list. It looks for them by the event’s name, like search: “Club championship” also finds “Club championship B” of the same years.
• Tournaments per year, by the year of the first game, and By rate of play.

How you play

It comes from the engine analysis written into the games: that of automatic analysis, which counts every move with the loss it judged, or the evaluations that come with games analysed elsewhere. Without analysed games the chapter is empty, and says so.

• Accuracy, where theory moves count as perfect, and Average loss, how much you give away on average at each move.
• Move quality: best, inaccuracies, mistakes and blunders. Under Best, how many moves have Good move (!) and Brilliant move (!!): only the app’s analysis gives them, and the lines are there when it has given at least one.
• By phase: your accuracy in the opening, middlegame and ending, beside your opponents’ in the same games.
• Pressing, level, under pressure: after your moves, how often the position was won, level or lost.
• Decided by one move: the eight most recent games that a single move decided. A move of yours lost a position that was not lost, or let a won position go, or an opponent’s mistake gave you the win. A click opens the game in the editor, on that move. It is the same rule as the first line of the analysis summary, in the editor.
• Games thrown away: those in which you had a won position and did not win, draws included.
• Opportunism: after the opponent’s mistakes, how many times your reply was not a mistake in turn.

Time

It comes from the clock recorded on the moves: games downloaded from the online sites have it, those entered by hand usually do not. The time of a move, when the game does not write it, is worked out from the clock if the time control has a single period, as online.

• Seconds a move, and Time spent by phase.
• In time trouble: in how many games your clock went below a tenth of the starting time (30 seconds if the time control is not known), and how many moves you played there.
• On the clock at moves 20 and 40: the time you and your opponents had left, as a percentage of the starting time, so that different time controls can be put together.
• Quality under pressure: your accuracy in time trouble and with time, and in long thinks (from a twentieth of the starting time, 5 minutes if the time control is not known) and in the other moves.

Free and Pro

Portrait is free; the other chapters belong to Pro: without Pro they stay in the list with the PRO mark, and the page says what they would show. In brief then has only the Portrait’s lines: the Elo and the Score % by colour.
