Sample report

You win by punishing early mistakes. Games that end by move 20 score 63% (215 games), against your 52% overall, and 172 of your wins are by checkmate. You lose to one-move oversights, not to the clock. You miss or allow mate in one, or drop a piece in a trade. You usually play these moves in a few seconds with half your time left: your losses end with 4:52 on the clock on average, and 162 of 168 engine-flagged errors came with more than 2 minutes left. You still gained 290 points because your accuracy went up while your opponents got stronger: they averaged 743 in September and 881 in November.

• Rating: you climbed faster than before, +290 now (628 → 918) against +240 last period (388 → 628).
• Accuracy: it rose from 70.5 to 72.3.
• Score: it dipped from 54% to 52%. The samples are quite different (850 vs 532 games), so treat this as flat, not as a decline.
• Inside the period: September scored 54%, October 51% and November 57%. November has only 46 games, so that last figure is a hint, not a fact.
• Average rating: the second half averaged 865, against 770 in the first half.

What stayed the same is the type of loss. More than half your losses are by mate (199 of 377).

1. 1.e4 e5 2.Nf3 against unusual replies. When Black does not answer with the usual moves, you score 77% (39 games). In the last 100 games you won all four of these (28 Oct · vs 879 · won, 11 Nov · vs 871 · won, 11 Nov · vs 922 · won, 11 Nov · vs 893 · won). Keep 1.e4 and 2.Nf3.
2. Finishing fast when the opponent slips. Games decided before move 16 score 64% (111 games). You won by mate in 12 moves in 7 Nov · vs 882 · won and in 14 moves in 11 Nov · vs 922 · won. Your habit of looking for attacks on the enemy king works.
3. Playing in the afternoon. Afternoon games score 59% (182 games) with your best accuracy, 74.5. Night scores 50% (449 games) and late night 51% (201 games). Move sessions to the afternoon when you can.

1. Moving without checking both sides' checks. Mate decides 199 of your 377 losses. Five of the ten critical positions are mate in one: missed in 30 Oct · vs 811 · lost, 7 Nov · vs 874 · lost and 12 Nov · vs 927 · lost, allowed in 28 Oct · vs 906 · lost and 10 Nov · vs 922 · lost. 7 Nov · vs 859 · lost also ended with a mate in one you allowed. Before every move, run a "blunder check": list your checks, captures and threats, then the opponent's replies to your move.
2. Deciding critical moves in seconds. In those positions you spent 0–7 seconds on the move (28 Oct · vs 895 · lost, 29 Oct · vs 808 · lost, 30 Oct · vs 811 · lost, 7 Nov · vs 874 · lost, 8 Nov · vs 887 · lost, 10 Nov · vs 922 · lost, 28 Oct · vs 906 · lost, 29 Oct · vs 872 · lost). Your losses end with 4:52 left, and no engine error came under 30 seconds of clock. You have the time. Spend 20–30 seconds whenever a capture, a check or a trade is on the board.
3. Resigning early. 29 of your last 48 losses were resignations. Some came very fast: 29 Oct · vs 849 · lost after 3 moves, a pawn down, plus 7 Nov · vs 860 · lost (9 moves), 29 Oct · vs 872 · lost and 30 Oct · vs 826 · lost (12) and 29 Oct · vs 808 · lost (13). At your level, opponents throw games away too. You had 39 comebacks in the analyzed games, and 196 of your wins came from opponents resigning. Keep playing unless you are down a queen with nothing going on.

Week 1

• Do 15 minutes of mate-in-one and mate-in-two puzzles every day. Track your daily success rate.
• In every game, say "checks, captures, threats — mine, then theirs" before each capture or check. Spend at least 20 seconds on those moves. Measure it by reviewing 3 losses at the end of the week: your decisive moves should no longer take under 10 seconds.
• Play no more than 5 games per session.

Week 2

• Review the five Scotch games listed above (30 minutes), then play them with the "one extra queen move" rule. Track your Scotch score over the week.
• Do 20 minutes of pawn-ending practice twice.
• Follow a no-resign rule unless you are down a queen. Count how many of the week's losses you played to the end and how many you turned around.

1. Mate in one and mate in two, both sides (top priority). This covers your 199 mate losses and the five mate-in-one critical positions. Do 15 minutes a day of Chess.com puzzles with the mate themes. Then set up 28 Oct · vs 906 · lost, 30 Oct · vs 811 · lost, 7 Nov · vs 874 · lost, 10 Nov · vs 922 · lost and 12 Nov · vs 927 · lost on the board and find the mate yourself before checking the answer.
2. Counting material before trades and captures. You lost or misplayed material in exchanges in 29 Oct · vs 872 · lost, 29 Oct · vs 808 · lost, 30 Oct · vs 826 · lost and 8 Nov · vs 887 · lost. For each one, write the trade sequence move by move and add up what each side gets. Do 10 minutes a day of puzzles where one side wins a piece.
3. Scotch principles after 5.Qxd4. Review 29 Oct · vs 850 · drew, 7 Nov · vs 837 · lost, 7 Nov · vs 873 · lost, 8 Nov · vs 887 · lost and 8 Nov · vs 888 · lost (30 minutes total). In each, mark every queen move in the first 10 moves and where your king castled. Then play the Scotch in a few unrated games with one rule: no more than one more queen move before move 10.
4. Simple endings. Games that reach move 41 score only 41% (253 games). 28 Oct · vs 895 · lost shows a pawn race, and in long games your clock gets low (28 Oct · vs 893 · lost, 11 Nov · vs 939 · lost, 12 Nov · vs 930 · lost, 12 Nov · vs 927 · lost). Spend 20 minutes twice a week on king-and-pawn endings and stopping a passed pawn with your king. A passed pawn is one with no enemy pawn able to block or capture it.

• Prefer the afternoon. If you play at night, which is when most of your games happen, keep it to one short session.
• Do 5 puzzles before your first game: game 1 of a session scores only 50%.
• Stop after 5 games. Game 6 onward drops to 50%.
• After a loss you can keep playing, since your results do not drop. First look for 1 minute at the decisive move in the Chess.com analysis.
• Keep the clock habit simple: with 10 minutes you can afford 20–30 seconds on every capture and check. Losing on time is rare for you (10 of 377 losses).
