Luis Lazaro Aguero Jimenez (poseidon5191)
Grandmaster of the 64 Squares
Meet Luis Lazaro Aguero Jimenez, a Grandmaster whose chess prowess slices through defenses like a hot knife through butter – or at least a well-prepared pawn structure. Also known by the formidable username poseidon5191, Luis has conquered blitz arenas with scores that would make even lightning think twice before striking.
Achievements & Peak Ratings
- FIDE Title: Grandmaster
- Peak Blitz Rating: 2750 (April 2025)
- Peak Bullet Rating: 2534 (January 2025)
Style & Strengths
With an average of ~75 moves per win in blitz, Luis is a true marathoner of the chessboard, often battling into the endgame, where about 78% of his games conclude. An expert tactician, he boasts an impressive 89% comeback rate after falling behind, and doesn't just survive losing a piece but wins over half those scrappy games too.
He's not one to quit early either – his early resignation rate hangs around a humble 2.54%, proving that when Chess.com servers go down, it's probably not due to him rage quitting.
Competitive Spirit & Records
Luis has played over 700 blitz games under his favorite (top secret) opening, winning nearly 57% of those battles. While he conquers many opponents effortlessly, a curious quirk: some players have a perfect loss record against him, such as innocuousquestion and kot60, who might want to reconsider their careers or at least their opening choices.
His longest winning streak stretches to a mighty 15 games in a row, demonstrating his capability to channel chess zen mode for extended periods—though his current streak is resting at a humble zero. It's all part of the Grandmaster life: one day you're on a hot streak, the next you're plotting your triumphant return.
Time-of-Day Wizardry
Night owl or early bird? Luis is apparently a bit of both—his best chess-playing hours are at odd times like 2 AM and 3 AM, where he claims a 100% win rate! So if you want to faceposeidon5191 and live to tell the tale, avoid queuing up for a game at the witching hour.
Recent Glories & Battles
In one of his latest masterclasses, Luis executed a brilliant checkmate finishing from the whites against LeoLV10 at a 2741 rating level, displaying patience and precision in an intense Caro-Kann Defense encounter. Just days before, he also out-timed SkeraNCitaM and outmaneuvered benkoclub with yet another checkmate, showcasing both rapid tactical flair and time management savvy.
But every hero has an off-day; even Luis faced defeat by resignation against danielili123 in a hard-fought Indian Game. Losing with dignity is an art form too—and Luis proudly masters it.
Final Thoughts
Luis Lazaro Aguero Jimenez, aka poseidon5191, isn't just a chess player; he's a chess storm, sweeping through ranks and leaving a wake of checkmates and shattered defenses. Whether battling at lightning-fast speeds or engaging in long strategic duels, he approaches the royal game with skill, spirit, and just the right hint of mischief.
Quick summary for Luis Lazaro Aguero Jimenez
Nice momentum — your rating trend is clearly upward and your Strength Adjusted Win Rate (~56%) shows you’re beating similarly strong opponents fairly often. In bullet you’re doing many things well (activity, tactical shots, creating passed pawns) but the recurring issue is time management and a few risky opening choices that invite chaos when the clock is low. Below are concrete, focused points you can act on in the next week.
What you’re doing well (keep doing this)
- Creating active pieces and attacking the enemy king — many wins come from direct pressure and rook activity. That rook on the 7th / 2nd rank motif shows up in your wins.
- Converting material / pushing passed pawns — your ability to push and escort passed pawns to the queening zone is a practical bullet strength.
- Comfort in sharp lines and gambits — you score decently with aggressive openings like the Elephant Gambit and several gambit lines, which is useful in 1|0 games where surprise and initiative matter.
- Resilience in tactical melees — you find tactics under pressure and often trade into winning/endgame scenarios.
- Positive rating momentum — steady +26 over recent months. That means your study + practice is working; scale what’s successful.
Biggest weaknesses to fix (high impact)
- Time trouble / flagging: several games end on the clock against you even from playable positions. Bullet outcomes are often decided by clock, not just the board.
- Overcomplication in bad time — when low on time you keep making complicated moves instead of simplifying and using pre-moves safely. That costs games.
- Opening risk vs reward balance: gambits win points but also lead to chaotic positions where a single slip or a few seconds lost costs the game. Pick which games you want to gamble and which to play solidly.
- Endgame technique under the clock: some endgames (rook+pawn vs rook, connected passed pawns) can be converted faster with rehearsed patterns. Bullet requires muscle memory for these wins.
Concrete, short-term plan (next 7–14 days)
- Daily 10–15 minute micro-session:
- 5 minutes: Puzzle rush / 1-minute tactics to sharpen pattern recognition.
- 5 minutes: 10 simple endgame drills (king + rook vs rook, rook + pawn vs rook, opposition, basic pawn races).
- 5 minutes: 1|0 or 2|1 rapid blitzing focusing on one opening you’ll keep for the week.
- Opening housekeeping: choose 2 reliable bullet repertoire lines (one for White, one for Black) that lead to clear plans. Keep your gambit lines for games when you want to be creative.
- Time-control habit: in 1|0, start the game with a little rhythm — avoid long think on move 1–6. If you reach under 10s, switch to “safe mode”: simplify, trade queens, push connected pawns, and use safe pre-moves.
- Session for flagged positions: review 5 lost-on-time games and mark positions where you still had a winning/holdable position but ran out of time. Ask: could I pre-move, simplify, or trade to a winning pawn endgame earlier?
Practical bullet tips you can apply immediately
- Safe pre-moves: use them for captures that are forced or recaptures on squares where opponent cannot trick you. Don’t pre-move into ambiguous captures.
- Simplify when low on time: trade pieces (especially queens) if you’re ahead or even — endgame technique + clock beats messy middlegame in bullet.
- Use checks and forcing moves to win time on the opponent’s clock (they’ll think longer); forcing lines increase chance of opponent flagging.
- When ahead on material, aim for a plan (activate rook, push passed pawn, drive king) rather than calculating long tactics when time is low.
- If you have increment games available, practice the same positions with increment to build correct conversion instincts before doing them in pure-bullet.
Study drills (30–60 minute weekly routines)
- Tactics block: 20–30 minutes of mixed tactics (forks, pins, skewers, mating nets). Prioritize patterns you miss in your games.
- Endgame block: 20 minutes on rook endgames, opposition, and king-and-pawn races. Learn 3 key positions to convert quickly (Lucena ideas simplified for speed).
- Opening refinement: 10–15 minutes reviewing the main idea and 3 typical move orders for each bullet opening you play (not full theory — just plans and traps).
Game-specific notes (examples)
- Win vs teddybear4673 (Center Game style): excellent work turning active rook + passed pawn into a winning race. You pushed the connected pawns and used the king actively — classic bullet conversion. Here’s a replay of the late phase to study the pawn push rhythm:
- Loss vs chess_mad35: this was a flag loss. The position had counterplay but the clock pressure was decisive. Practice “safe-mode” simplifications so you don’t lose on time from otherwise playable positions.
- Win by mating patterns (example vs vicky-minaj): your use of back-rank/rook tactics was efficient — keep hunting those patterns in your tactics set.
Repertoire & opening advice
- Given your stats, keep one sharp/gambit option (you already score with gambits) but pair it with a solid fallback line for when you want less risk (e.g., switch from an Elephant Gambit to a solid Caro-Kann or similar if you’re short on time).
- Prepare 3 move orders and 2 typical middlegame plans for each chosen opening — not full theory. In bullet you win more by knowing the plan than memorizing long theory.
Targets for the next rating milestone
- Short term (2 weeks): cut flag losses in half — review 5 recent time-loss games and apply the “simplify when below 10s” rule.
- Medium term (1–2 months): improve conversion speed in rook + pawn endings so you convert 80% of winning endgames in <30s.
- Long term (3 months): consolidate the openings you play most (focus on your 2 best-performing lines) and increase your Strength Adjusted Win Rate toward 60%.
Final notes — mindset for bullet
- Bullet rewards simplicity and speed. If you’re unsure in a position, make the practical move (trade pieces, centralize king/activity) rather than chasing the “perfect” continuation when the clock is burning.
- Keep the training short and repeated — 10–20 minutes daily is more effective than long irregular sessions.
- Celebrate small improvements: fewer flags, quicker conversions, and steadier opening choices will compound into rating gains (you already have a solid upward slope).
If you want, I can create a 7-day training schedule tailored to the openings you prefer, or analyze 3 specific games in depth (point out exact move alternatives and short tactical patterns to memorize). Which would you like next?
