Jomar Costa
Meet Jomar Costa, a rapidly rising force on the chessboard who goes by the cunning username shilamarie. While some players play safe, Jomar treats the game like a thrilling roller coaster — expect both breathtaking wins and nail-biting losses!
About the Player
Jomar is no stranger to the intricacies of rapid chess, having played over 276 games in early 2025 alone, securing 162 wins. Despite being mercilessly hunted by tough opponents, his fighting spirit shines through with an impressive peak rapid rating of 1180 (achieved in May 2025). His blitz skills are nothing to scoff at either, boasting a top rating of 777 and a steady accumulation of wins.
Playing Style
Jomar has a flair for dramatic games. He averages 48 moves per victory and isn’t afraid to resign early — only about 3.5% of his games end prematurely in surrender. With a come-back rate of over 74%, he’s got the tenacity of a chess terrier, clawing his way back even when down a piece. He performs better with white pieces (60.3% wins) but black is also no disadvantage.
Favorite Openings
- Top Secret opening — his true signature, with over 182 games and 57% win rate;
- Bishop's Opening — where he occasionally surprises opponents with a cheeky 66.7% win rate;
- Also quite comfortable with the King's Pawn, Three Knights, and Queen's Pawn openings, often leaving foes scratching their heads.
Psychology & Timing
Jomar’s best time to play is around 7 PM, where his winning rate hits a perfect 100% (no pressure, right?). He’s been known to tilt occasionally (tilt factor: 6), but who doesn’t after a few losses? Mondays are a bit rougher, while Tuesdays and Fridays are his chess playgrounds.
Memorable Matches
One highlight was a rapid game on May 3, 2025, where Jomar, playing white, executed a superb Bishop's Opening. His opponent resigned under the pressure of an unstoppable knight fork. Earlier in the day, he also swept the board with a checkmate victory using the Sicilian Defense - O'Kelly Maroczy Bind Paulsen, showcasing his versatility.
Interesting Quirks
- He has a stronger winning percentage against lower-rated opponents (no surprise!) but accepts that stepping up to higher-rated challengers means a mix of win and loss stories.
- Jomar masterfully navigates mid-game tangle and endgames with high frequency, rarely giving up easily.
- When Jomar loses, it’s rarely a one-sided massacre — he keeps the battle close, much to the suspense of spectators.
Whether you meet shilamarie on the battlefield of rapid or blitz, expect clever strategies, daring attacks, and maybe a little bit of chess magic. Remember: it’s not just a game; it’s an adventure!
Quick summary for Jomar Costa
Solid blitz stretch — 10 wins, 7 losses. You show a real knack for sharp tactics and finishing attacks, but time trouble and occasional loose decisions are costing you games. Strength‑adjusted win rate (~0.67) shows you’re scoring well versus similarly rated opponents — now focus on converting that into steady rating gains.
What you’re doing well
- Direct attacking instincts: you create mating nets and tactical threats quickly (example: a game where you chased the enemy king with queen + knights and finished by force).
- Capitalizing on opponent mistakes — you punish overambitious queen excursions and hanging pieces instead of letting counterplay breathe.
- Opening variety: you’re comfortable playing many offbeat lines (you've scored in Caro‑Kann, Scandinavian and other less common setups).
- Practical finishing: wins include checkmates and successful exploitation of coordination advantages rather than relying purely on long endgame technique.
Main areas to improve (high impact)
- Time management — several games were decided by the clock. Try to keep a steady reserve of time in the middlegame so you don’t blunder in zeitnot. Consider playing slightly slower in the opening to build a comfortable 30–60 second buffer.
- King safety and simplification choices — when the opponent’s queen goes on a long raid (taking pawns or material), ask: can I trade queens or simplify? In a few games a material grab by the enemy queen led to decisive attacking sequences.
- Endgame/passed pawn handling — a recent loss shows a passed pawn queening while the clock was low. Practice basic passed‑pawn races and simple queen+pawn vs queen technique so you can convert or hold when time is tight.
- Opening consistency — mixed results in gambits (Vienna Gambit 0/2). If you like tactical messes, keep the gambits but study typical responses; otherwise adopt a more reliable “safe” setup for blitz to reduce early surprises.
Concrete drills and week plan (blitz-focused)
- Daily 10–15 minute tactics: focus on forks, discovered checks and mating‑net patterns (15 puzzles/day). This sharpens the finishing you already do well.
- 3× 10‑minute sessions per week with a single goal:
- Session A — Play a few 5|0 games and force yourself to keep 40–60 seconds at move 10 (practice slow early moves).
- Session B — Play 3|2 and practise using increment: finish the game with 10 seconds on the clock repeatedly without flagging.
- Session C — Play one slow 15|10 game and practice converting a small advantage without tactical fireworks.
- Endgame drill: 10‑minute practice of queen vs queen + passed pawn and basic rook endgames (set positions and play them 5 times).
- Opening mini‑project: pick two reliable openings (one as White, one as Black) and learn main plans, not deep theory — e.g. keep Caro-Kann Defense as a stable choice vs 1.e4 or a solid bishop development system vs 1.d4.
Practical blitz tips to implement now
- Before you move: glance for checks, captures and threats. This 1–2 second habit avoids most cheap losses.
- Trade queens early when you’re low on time and the position is equal — queen exchanges reduce tactical chances and flag‑loss risk.
- Make fast developing moves in the opening — don’t spend extra time on move 2–6 unless there’s a forcing tactic. Save your clock for the critical middlegame.
- If you win material, simplify and aim for clean technical finishes instead of hunting more complications that can backfire on the clock.
Examples from your recent games
- Win vs SlickWithIt11 — excellent exploitation of an exposed king after an opponent’s queen hunt. You converted with coordinated queen + knight threats. Study that finish and the tactical motifs you used.
- Win vs nikpoosh712 — delivered mate with active rooks and a final queen check. Reinforces strength in direct attacks.
- Loss vs abdelrahman-elkhawaga — the opponent pushed a passed pawn and you lost on time. Practice defending passed pawns and prioritizing clock management in similar endgames.
- Recurring pattern — both wins and losses show decisive moments that come down to a few critical moves under time pressure. Small improvements in clock handling will raise your score quickly.

Short-term action plan (next 2 weeks)
- Implement the 15‑minute tactics habit and play one 15|10 game per week.
- Pick two openings to stabilize your blitz repertoire — learn typical pawn structures and simple plans (not long theory).
- After each session, review one loss and one win — write down the turning moment and one alternate move you could have tried.
Motivation & next steps
Your win/loss split shows you’re already doing a lot right. Small, focused improvements — clock discipline, a short endgame routine, and targeted tactics practice — will convert many razor‑thin losses into wins. Keep the attacking flair, but add a little structure around time and endgames.
If you want, I can prepare:
- a 2‑week training schedule tailored to your daily availability, or
- a short annotated replay of the loss vs abdelrahman-elkhawaga highlighting defensive moves and how to handle the passed pawn, or
- an opening cheat sheet for two reliable blitz systems based on your current repertoire (one White, one Black).
