Chinguun Bayaraa - Candidate Master Extraordinaire

Known in the chess circles by the enigmatic username lProstoy, Chinguun Bayaraa is a formidable titled player crowned with the prestigious Candidate Master title by FIDE. Far from your average player, Chinguun commands the board with a mix of tactical wizardry and relentless determination that can turn the tides even when the odds look bleak.

Rating Highlights & Style

Chinguun has achieved a peak bullet rating of 2719 (February 2025) and a striking blitz peak of 2757 (May 2023), proving that speed chess is where this master truly shines. With an endgame frequency of over 88%, Chinguun loves the long haul, navigating the complexities of late middlegames and endgames like a seasoned navigator in a storm. Tactically, a comeback rate north of 90% means never counting Chinguun out—even when a piece has been lost, there's a 40% chance that the tables will be flipped.

Opening Repertoire & Memorable Moves

The Indian Game, specifically the East Indian Przepiorka Variation, is a favorite weapon, yielding a win rate of over 64% in bullet games. Queens Pawn Opening variations and the Sicilian Defense also pepper the palette. Not one to shy from complexity, Chinguun’s games often showcase deep strategic play sprinkled with sudden tactical strikes.

Notable Matches & Moments

Among many spirited battles, a recent thrilling victory against watermelonattackk ended in a memorable checkmate after a fierce and graceful dance of pieces. But even masters face trials: a recent loss by resignation to ShrookWafa illustrates that humility is part of the journey—after all, even Magnus slips occasionally.

A Personality on the Clock

With a quirky penchant for playing best around 1 AM, Chinguun’s psychological tilt factor stands at 13, meaning sometimes emotions play as big a role as skill (who doesn’t get a little grumpy losing a rook to a sneaky knight?). Surprisingly, resignation is sometimes the escape route, but rarely does it last; the longest winning streak boasts 12 consecutive victories.

Off the Board

While the data is silent on hobbies outside chess, one can imagine Chinguun Bayaraa relaxing with a steaming cup of Mongolian milk tea, pondering the mysteries of the board and life alike.

Chinguun Bayaraa proves that chess is not just a game of pieces but a thrilling saga of patience, resilience, and occasional caffeine-fueled brilliance.

Hi Chinguun Bayaraa!

Great job keeping an active schedule and steadily facing 2600-rated opposition. I’ve reviewed your last several rapid games and distilled some insights that should help you convert more of those promising positions into points.

What you already do well

  • Consistent opening repertoire – Your King’s Fianchetto / East-Indian set-ups (1.d4/1.g3 & 2.Bg2) give you playable middlegames against most replies and keep preparation time low.
  • Piece activity – In wins vs. shashacfc and ford you repeatedly placed knights on e5/d6 and bishops on g2/b7, demonstrating good feel for strong outposts.
  • Practical swindling skills – Even in lost positions you create counter-chances (e.g., …Nf3+ tactic against javicio). That fighting spirit is valuable in fast time controls.

Main themes to address

1. Time management ⏱️

Five of the last seven losses ended by flag. Your play rate drops sharply after move 25:

01234567891011121314151617181920212223100%0%Hour of Day
  • Aim to keep ≥ 20 seconds on the clock until the endgame. Consider adopting a “10-second rule”: if your clock dips under 10 s, make the safest reasonable move rather than the perfect one.
  • Use the opponent’s time to preview branches. Practice chunking evaluations (“king weak, my knight dominates, push passed pawn”) instead of calculating every line.

2. Critical move accuracy vs. …Nc5/…Nd3 motifs

Two recent defeats (vs. Pham Nam Quan and blacknightmare91) featured …Nc5-d3 or …Nc5-e4 forks that picked off key pawns. Train tactical patterns such as the fork, overloaded piece, and zwischenzug in positions arising from the King’s Indian/Symmetrical English.

3. Endgame conversion

You achieved winning rook endgames against VierPaarden and coach_N but needed ~70 moves to finish one and flagged in the other.

  • Re-visit basic Lucena, Philidor, and “bridge-building” techniques for R + P vs. R.
  • When R+4 vs. R+3 arises, activate the king immediately—don’t chase pawns first.

4. Early middlegame plans in your repertoire

You often reach very similar pawn structures:

  White: pawns d4-e4-c3 vs. Black: …d6/…c6/…e5
  
  • Add model games by Gelfand and Kramnik on the East-Indian to see typical pawn breaks (c4, f4, dxe5 & f5).
  • After securing e5 with a pawn, consider f4-f5 pawn storm sooner—waiting until move 20 lets Black regroup.

Personalized improvement plan

  1. 30-minute tactics slice – Focus on intermediate-move motifs and knight forks.
  2. Endgame drill (15 mins) – Use Nalimov/online table-base trainer: play R+P vs. R from both sides until you convert in under 60 seconds.
  3. Opening refresh (weekly) – Annotate one GM King’s Fianchetto game; write two-sentence summaries of each critical plan.
  4. Blitz time-control exercise – Play 5 + 5 with a hard rule: never let the clock fall below opponent’s time by 50%. Track performance with

    .

Your peak so far

Keep embracing a growth mindset—small, deliberate tweaks will add up quickly at your level. Looking forward to your next tactical masterpiece!
