Profile Summary: cjlammert
Meet cjlammert, a chess enthusiast whose journey is a testament to perseverance, strategy, and a dash of quirkiness. Starting out with a humble rapid rating barely scraping 700 in 2010, this player has steadily climbed the ranks to peak rapid ratings soaring above 1500 by the mid-2020s. A true student of the game, cjlammert doesn't just play chess – they live it, breathe it, and occasionally resign too early (just 2.17% early resignation rate, though who's counting?).
Known for a love of the Pirc Defense and its various offshoots, not to mention some sneaky excursions into the Queens Pawn Chigorin and Scotch Game, cjlammert showcases a versatile opening repertoire that keeps opponents on their toes. With a 62%+ win rate in the Pirc Modern Geller System and 78% smashing success in Modern Defense, it’s clear this player favors dynamic counterattacks and a tactical approach.
But the story isn't just about openings: in daily chess, the winning streaks tell a tale of resilience and cunning, with an impressive 29-game longest winning streak and a comeback rate nearing 70%. When down material, cjlammert fights back with vengeance, winning nearly half of those grim scenarios. Yet every warrior has their Achilles' heel, and the bullet records show room for improvement – a humbling record with only three wins.
Speaking of style, an aesthetic eye would notice cjlammert loves long, strategic battles (average 57 moves in wins, 65 in losses), showing patience and a deep understanding of endgames, which happens more than 62% of the time. Their psychological game? A tilt factor of 12 suggests some fiery passion, but nothing too catastrophic. Notably, their best time to conquer the board is around 10:00 AM – perfect for early risers who fancy a checkmate before lunch.
Against regular rivals, cjlammert wields a veritable arsenal: a stellar 94.68% win rate against the frequent opponent hackerpat, contrasting sharply with a frustrating 1.64% record against chessclassroom64. The highs and lows of chess friendships!
Fun fact: this player's fastest wins have come with checkmates in under 10 moves, proving that sometimes, it’s not about the long haul but catching your opponent napping. Their latest games showcase a blend of sharp tactics and endgame prowess, culminating in graceful resignations and decisive checkmates alike.
Whether you meet cjlammert on a rapid board or challenge them to a daily marathon, expect a thoughtful and determined opponent who might just make you laugh with a creative sacrifice or two before making you admire the checkmate.
Quick summary of the last games
Nice run — several clean wins and a couple of fast decisive games. You’re converting advantages and you’re comfortable playing for concrete targets (passed pawns, mate nets). Recent highlights: a technical queenside breakthrough and a good endgame conversion, plus a sharp tactical finish by mate in the opening from the black side.
- Most-recent win vs zsckook — a long middlegame battle that ended with you queening/king activity and a time win. See the final position below.
- Win vs giovanniaco — you converted a material/positional edge into a resignation.
- Loss vs vlajan — an early queen sortie punished you; a reminder to watch early tactics and queen checks.
What you’re doing well
- Closing out winners: you convert endgame/technical advantages reliably — several resignations and a final push that forced the opponent off the board.
- Practical awareness in time trouble: you win on the clock when needed — useful in rapid (but see caution below).
- Opening variety: you have strong results in several systems (Caro-Kann, Australian, English) — that breadth makes you hard to prep against.
- Tactical alertness in sharp positions: you find mates and combinations (example: the quick Qa3# game vs ypey).
Main areas to improve
These are recurring themes from your recent games and the season stats — small changes here will raise your conversion rate and reduce sudden losses.
- Opening safety early on — avoid leaving your king exposed to early checks and queen incursions. In the Vlajan game an early queen move (Qe4) created tactical problems; prioritize simple development when the opponent has active queen checks.
- Time distribution — you sometimes rely on flagging. That works, but it’s risky. Spend a consistent small amount of time each move early (build an opening rhythm), and leave more time for sharp moments later.
- Loose pieces / hanging tactics — you have the tools to spot combinations, but occasionally a piece becomes en prise after a sequence. Drill pattern recognition for forks, pins and skewers (the usual suspects).
- Transition play: when you win material, simplify accurately. A clean path from advantage to endgame (trade sequence, pawn structure) reduces chances for swindles.
Concrete next steps (weekly plan)
Small focused habits give the biggest rating gains in rapid.
- Daily tactics: 15–20 minutes on tactical puzzles (forks, pins, discovered attacks). Focus on recognition, not just speed. Use mixed difficulty; finish every missed puzzle by reviewing the motif.
- One opening refresher per week: pick 1 line you play often (example: your English/Caro setups). Review 5–8 typical move orders and the common tactical shots for both sides. Add 1 new short plan (pawn break or piece rerouting).
- Endgame basics twice a week: king+pawn endings, basic rook endings and outside passed pawn technique. Practice the Lucena and basic opposition patterns — these pay off when you convert material edges.
- Play 5 rapid games with the specific constraint: “no flagging”. Try to stop moving instantly in the last 30 seconds; force yourself to use time earlier. Review one game in depth (15–20 min) after each session.
Practical tips for the next game
- Move 1–10 checklist: develop minor pieces, castle, avoid premature pawn moves that create holes. If the opponent brings their queen out early, ask: "Can I chase it with tempo?" or "Do I drop material running after it?"
- When ahead: exchange pieces to reduce counterplay unless you gain a concrete plan (passed pawn, mating net). Simpler positions = fewer swindling chances.
- Time handling: on ambiguous middle games, take an extra 10–20 seconds to calculate candidate moves instead of instant replies — that saves time later.
- Tag to watch for: Loose Piece — if a move allows tactics that hit an undefended piece, pause and recalc.

Notes & next-review targets
- Short-term: reduce "fast loses" from early queen tactics. Spend 1–2 training sessions on opening traps and opponent queen checks.
- Medium-term: aim to convert more wins without relying on time; track how many victories come from flagging vs resignation. (You had a recent time win — useful, but convert earlier if possible.)
- Long-term: keep the current opening breadth but deepen 2 favorite systems into real repertoires — pick a main and a sideline to study 2 hours each per month.
