Rosa Ratsma - Woman International Master (WIM)
Known in chess circles by the username roos96, Rosa Ratsma is a formidable Woman International Master whose strategic mind and tactical awareness have made her a rising star on the chess scene.
Career Highlights
Rosa's journey through the ranks reflects a steady ascent, especially in rapid and blitz formats. With blitz ratings hovering around the 2000+ mark and rapid peak ratings near 2350, Rosa demonstrates formidable speed and precision. Her impressive longest winning streak of 13 games is testament to her relentless focus — she might even forget to eat if she's on a roll!
Playing Style
Rosa is a meticulous player who enjoys long endgames, with over 76% of her games extending into the endgame phase. She averages about 71 moves per victory, meaning she's happy to slowly grind out a win rather than rely on quick tricks. Her white pieces bring her a robust 69.4% win rate, though she remains a solid competitor with black too.
Tactical Skills
Known for incredible resilience, Rosa boasts a 79% comeback rate and a flawless 100% win rate after losing a piece — clearly, losing material only fuels her fire. Rosa's opponents are wise to be wary of any early piece grabs, as she turns disadvantages into victories with uncanny flair.
Opponent Interactions
While some opponents have managed to evade her deadly grip, others have become her favorite targets. Rosa holds a perfect win record against several players including rootje8, austen48, and m-a-g-g-i-e, among others. However, despite many attempts, she has yet to crack the code against maaikee — the rivalry continues!
Fun Facts
- She never resigns early – giving her opponents false hope until the very last move.
- Friday is undoubtedly her lucky day, boasting an impressive nearly 90% win rate.
- Her blitz games sometimes resemble a rollercoaster: from a highest rating of 2159 to a surprising dip at 1679, she bounces right back up like a chess superhero.
Whether it's blitz or rapid, Rosa Ratsma's combination of tactical brilliance, psychological resilience, and an almost comical ability to win after losing material makes her a player to watch and a joy to follow.
Hi Rosa, here’s a tailored review of your recent play
Quick snapshot
- Current mood: energetic attacker with a flair for initiative.
- Best recorded peak so far: 2346 (2021-04-03).
- Activity trend: .
Your core strengths
- Initiative-driven opening choices
• Rossolimo/Sicilian sidelines and Ruy Lopez Exchange give you early pressure.
• You consistently castle early and place rooks on active files (e.g. 10.Rd1! in your win vs Austen48). - Rook-lifts & attacking imagination
Example tactic:– converting a positional edge into a decisive tactic. - Piece activity over material
You’re happy to sacrifice pawns (17.Nxe6 in the English and 18.Nf6+! vs Berlin) to keep the initiative. This works well against sub-2200 opposition.
Recurring issues to address
- Clock management
Four of your last six losses were on time, often in positions that were still defendable or even better for you. Aim to reach move 20 with ≥50 % of your original time. A simple habit: spend at most one “long think” (≥30 s) in the first ten moves. - Over-extended pawn storms
In the French Exchange loss to Maaikee you pushed 6.g4/12.g5 before development was complete and the centre was fixed. Use the three-question filter before advancing a wing pawn:- Is my king completely safe?
- Is the centre locked or firmly under my control?
- Can I bring at least three pieces to the target area within three moves?
- Handling of equal endgames
Games vs julinha97 and Irochka83 show difficulties converting or holding rook-and-pawn endings. Your technique is solid when you have a clear material edge, but less so in equal or slightly worse endings. - French & Sicilian structures as White
You know plans, but sometimes mis-place pieces (e.g. 18.Bh1?! allowing ...d3). Spend a session on model games that feature the Nd2–f3–e5 plan in the French and the f4-f5 break in the Rauzer.
Action plan for the next 30 days
| Focus area | Practical drill | Goal |
|---|---|---|
| Clock handling | Play 10 + 5 games limiting yourself to 60 s total for moves 1-10. | Finish opening with ≥80 % time left in 80 % of games. |
| Defensive technique | Weekly study of 5 master games where the defender holds a worse position; annotate passive vs active defence choices. | Improve save-rate when worse to at least 35 %. |
| Endgame fundamentals | Solve 20 rook-and-pawn endgame studies (≤10 moves) on Sunday mornings. | Reach 80 % accuracy. |
| Opening refinement | For each of your main lines, pick one critical branch and play it in sparring; review with engine after each session. | Add one new idea per line to your personal repertoire sheet. |
Mindset tip
Treat each game as two separate battles: the position and the clock. Winning only one of them is rarely enough.Keep up the momentum!
Your attacking instincts are your hallmark; polishing the defensive and time-management side will make you a more complete player and push you beyond the 2300 rapid mark.– Your Chess Coach
