Maurilio Ferraz (aka maubom) - The Chess Maverick
Maurilio Ferraz, better known in the chess realms by his username maubom, is a player who wrestles with the sixty-four squares with a unique blend of grit, tactical awareness, and just enough mischief to keep opponents on their toes. With a peak blitz rating of 1172 achieved in early 2018 and a formidable rapid zenith of 1270 as recent as September 2023, Maurilio’s dedication to the game is both commendable and occasionally unpredictable.
Specializing in blitz and rapid formats, maubom demonstrates a tough competitive spirit, boasting nearly as many wins as losses in blitz (1085 wins vs. 1106 losses) and a very balanced rapid record. With over 2,000 blitz games under his belt, his experience is vast—even if his average rating likes to dance around the 900-1100 range in blitz. Bullet chess seems to be a rollercoaster for Maurilio, with a notable peak back in 2013 at 984, but recent bullet performances have resembled a wild ride with ups and downs that would make even the most seasoned chess psychologist chuckle.
Maurilio's favorite openings remain shrouded in mystery ("Top Secret"), but he has shown sparks of boldness with variations like the Scandinavian Defense and the Italian Game from time to time. His playstyle leans towards long battles—average moves per win and loss hover around the high 50s—proving he has patience and endurance, occasionally enduring some rough losing streaks but always managing a comeback, as evident from a remarkable 76.5% comeback rate after losing material.
Behind the scenes, maubom’s psychological resilience stands out. Despite a tilt factor of 11 (because yes, even chess warriors get frustrated), he battles back with a solid win rate after setbacks. His best performance hours span early mornings around 8 AM, although he’s been known to shake things up late at night with some surprising wins.
Off the board? Maurilio’s humor and unpredictability might be compared to his chess—sometimes brilliant, sometimes bewildering, but always entertaining. His recent games show a penchant for strategic maneuvering and opportunistic resignations from opponents recognizing the sinking ship. His latest victory, a graceful queen-side showdown won by resignation, cements maubom’s reputation as a player who knows when to strike and when to hold their ground.
In a nutshell, Maurilio Ferraz’s chess journey is one of perseverance, tactical daring, and the occasional surprise move—keep an eye on maubom; the chessboard is never dull when he's in play!
Quick summary for Maurilio Ferraz — bullet games review
Nice recent form: your rating trend is climbing and your strength‑adjusted win rate (~50%) shows you’re winning more than you should by pure luck. You create practical pressure, convert activity into threats, and you score victories on the clock — all great assets for 60s bullet. The main leaks are time trouble and a few tactical/king‑safety oversights that lead to clean losses. Below is focused, practical feedback with actions you can apply immediately.
What you do well
- You make the opponent solve hard problems under time pressure — several wins came from active rooks and passed pawns and forcing simplifications (see wins vs callisthenie and seaworld_pirates).
- Your opening choices include some high‑yield lines (good historical results with Czech Defense and Amar Gambit). Those give practical middlegame chances you convert well.
- You simplify into technical endings or active rook+queen raids when you’re ahead on the clock — that pragmatic approach keeps winning chances alive in bullet.
- You’re willing to seize initiative and play concrete moves rather than waiting for long maneuvering, which suits bullet play.
Concrete mistakes from recent games (what cost you)
- Missed tactical checkmate: loss vs pg38920 ended with a direct Qg2# pattern. The sequence shows one missed opponent check/fork before you made a routine developing move — a classical “I didn’t scan for checks” failure.
- Time management flip‑side: you often win on the clock but you also lose on the clock (opponents seaworld_pirates and callisthenie were flagged in other games). That inconsistency means you rely on the clock too much; when the opponent converts an extra tactic you’re punished.
- Back‑rank / king safety exposure: some middlegames had no luft or left escape squares open. Back‑rank mates and queen checks appear in your losses — a single 1–2 second safety check would have prevented them.
- Opening drift: you use many different systems. That’s fine for practice, but in 60s you benefit from 1–2 go‑to setups so your instincts kick in immediately.
Immediate bullet fixes (apply in your next session)
- Two‑second safety habit: before every move, take ~1–2 seconds to ask (A) is any opponent check or forcing tactic available? (B) am I leaving a piece en‑prise? Make it automatic even when low on time.
- When clock < 12s: simplify. Trade queens or reduce tactics. In bullet, simple technical moves win more reliably than risky combinations when you’re low on time.
- Use pre‑moves only for safe recaptures and obvious pawn pushes — avoid pre‑mousing in sharp positions with queen/knight forks.
- Leave a small luft early (a pawn move or a rook lift) when your back‑rank can be threatened. It costs almost nothing and prevents instant disasters.
Opening guidance — keep it simple
- Double down on what works: prioritize the systems with best win rates for you (for example Czech Defense and Amar Gambit). Memorize plans to move 6–8, and typical piece placements rather than long forced theory.
- Shelve or simplify low‑yield lines: reduce the number of different openings in a single session. If you use the Australian Defense or complicated Colle sideline, choose one safe sideline only so you don’t waste time choosing moves mid‑game.
- Have a default “safe” move: when you don’t remember the theory, prefer a simple developing/king‑safe choice instead of hunting a novelty in bullet.
Two‑week focused plan (short, repeatable)
- Daily (12–20 min): tactics warm‑up — 5 easy puzzles before a bullet session to sharpen pattern recognition (forks, skewers, discovered checks, back‑rank mates).
- Every other day (15–25 min): openings drill — pick 2 systems (one White, one Black). Drill typical moves and two opponent replies to build reflexes.
- 3× week (15 min): endgame basics — rook+king vs king, basic pawn promotions and opposition. These are high‑value in bullet conversions.
- After each 8–10 bullet games: quick review (3–5 minutes) — pick one decisive win and one loss. Note the exact moment you panicked, missed a tactic, or allowed a mate.
- Play a handful of increment games (3+2 or 5+3) each week to practice clean technique and reduce the habit of moving too fast in winning positions.
Drills & habits to build
- “3‑puzzle warmup”: do 3 tactical puzzles instantly before each session — your brain wakes to the patterns and you’ll miss fewer simple tactics in the first 10 moves.
- “15s rule”: if your clock drops below 15s and the position is sharp, choose simplification over searching for a miracle tactic.
- Practice the two‑second safety check on every move for a week — it becomes a reflex and prevents mate/check oversights.
- Record one game per day (or save the PGN) and annotate just three turning points: a missed tactic, a time decision, and an opening slip. Keep annotations to 2 minutes each.
Study this recent win (replay & what to look for)
Replay the following win slowly. Ask: where did I force simplification, how did I create threats, and when did I use the clock advantage?
Study points:
- Where did you convert activity into a permanent weakness (weak pawns, passive bishop, back‑rank ideas)?
- Which simplifications were automatic and which cost you time? Mark the moves where you used more clock.
- Could any of your opponent’s counterplay have been neutralized earlier with a small prophylactic move?
Final checklist before every 60s game
- 3‑puzzle warmup (1–2 minutes).
- Pick one opening plan and stick to it for the session.
- Before each move: two‑second safety check (checks/mates & hanging pieces).
- If clock < 12–15s: simplify or make safe developing moves — avoid tactical hunting.
You're trending up and the improvements are real. Clean up the time leaks and make the 2‑second safety habit automatic — that single habit will eliminate many of your losses. If you want, I can produce a 14‑day drill schedule tailored to two openings you name (pick any two and I’ll customize).
Games to review next (quick picks)
- Loss with tactical mate: review vs pg38920 — focus on the moment before Qg2#.
- Win where you flagged: review vs seaworld_pirates — see how you steered to simplification and used the clock.
- Win with active rook play: review vs mohamaadrezaofficial (PGN above) — learn the critical plan transitions.
