Jan Sodoma – The International Master with a Secret Opening
Known in chess circles and online as sodikus, Jan Sodoma is an International Master whose gameplay is as mysterious as the name of their favorite opening, simply dubbed "Top Secret." With a rating that has soared as high as 2366 in blitz and 2343 in rapid formats, Jan combines strategic brilliance with a flair for the unexpected.
Jan’s career is peppered with impressive stats: a longest winning streak of 10 games, a comeback rate that will make you raise an eyebrow at adversity (87.67%), and a flawless record when down a piece—because giving up is just not their style.
Playing style? Picture marathon matches lasting over 70 moves on average for wins and losses alike, underlining a methodical, endgame-loving strategist who rarely resigns early. Jan’s success with the white and black pieces is nearly equal, with win rates hovering around 67% and 69%, respectively.
Jan has a peculiar habit of dominating the chessboard at odd hours—100% win rate at 12 AM, 1 AM, and even at 22:00—while their Sundays are almost sacred chess days, boasting a striking 90% win rate.
Socially, Jan is no stranger to repeated battles against familiar foes like donyen and zdenekdavidek, with a respectable win rate against them. Yet, some opponents seem to be their kryptonite, showing zero win rate, giving Jan plenty of motivation to keep training.
In the bullet and blitz arenas, Jan's games are anything but hasty; despite the speed, they maintain above 60% win rates, proving that rapid reflexes are only half the battle—mental endurance and tactical acumen clinch the rest.
With a tilt factor of just 3, Jan keeps their cool under pressure—quite impressive for a player who racked up 40 wins in 52 blitz games in 2020 alone. It seems Jan sodoma’s journey continues upward, one secret opening at a time.

What You Are Already Doing Well
- Dynamic piece play. In several recent wins you voluntarily seized space and kept your pieces on active squares (e.g. 14.Ne5! and the rook lifts Rh3–g3–f3 in your win against zdenekdavidek). This makes life hard for your opponents right out of the opening.
- Tactical alertness. Your victory versus hnutt featured the nice …b4 …a3 …bxa2+ tactic that culminated in a quick mate. You spot combinations quickly and rarely miss straightforward forks, pins, and skewers.
- Opening variety. With White you alternate between flexible Nf3-d4 systems and direct 1.e4 lines, while with Black you handle both 1.e4 e5 and Sicilian structures. This versatility will pay off as you climb further.
- Pressure on the clock. Many opponents flagged or resigned in inferior positions. Consistent, steady moves force errors and time pressure—an underrated practical skill.
Main Improvement Targets
-
Time management in critical moments.
Four of your five most recent losses were on time, sometimes from roughly equal or even favourable positions (e.g. the rapid loss to Cepamwa). Try:- Using a simple “30-second rule”: if you have >30 s on the clock, move when your candidate is safe rather than hunting for perfection.
- Playing several 15 | 10 or longer games weekly to practise deeper calculation without severe time pressure.
-
End-game conversion.
When the queens come off you sometimes struggle to convert extra pawns (see the 2021 game versus adziugan). Work on the “four rook + pawn” and basic rook-endgame techniques—especially the Lucena and Philidor positions (Lucena Position, Philidor Position). -
Choosing principled lines against the Sicilian.
In your last loss you employed the off-beat Bowdler Attack (2.Bc4). While creative, this gave Black easy equality and counter-play. Consider switching to one main-line you genuinely enjoy (e.g. the Alapin 2.c3 or Open Sicilian with 3.d4) and study the key pawn breaks so you play from a position of strength rather than surprise value. -
Pawn-structure awareness.
Repeated early h-pawn thrusts (11.h4 – 12.h5 vs zdenekdavidek) are powerful when timed correctly, but can also over-extend. Ask “What squares will be weak if this pawn moves?” before pushing flank pawns in the middlegame.
Illustrative Moment
From the recent defeat to Cepamwa you missed Black’s decisive rook infiltration. Replay the critical sequence and note how quickly the activity snowballed:
Action Plan for the Next 4 Weeks
- Daily: 20–30 tactic puzzles focusing on intermediate moves and defensive resources.
- 3× per week: Play a 15 | 10 game, save the PGN, and spend 15 minutes analysing without an engine, then 10 minutes with one.
- Weekly: Study one thematic rook end-game video or chapter and recreate the position on a board.
- Track progress: Use
• to see if certain times of day correlate with blunders,
• to spot fatigue patterns.
Final Thoughts
Your attacking instincts and tactical vision already place you above average in your rating bracket. By tightening your clock handling, solidifying an anti-Sicilian repertoire, and mastering a handful of fundamental end-games, you will be well-equipped to break through to the next rating tier. Keep the enthusiasm high, and good luck in your upcoming battles!
