Overview
Martin Cuhra (username: HCMotorCB) is a humorous and hard-hitting FIDE Master known for preferring Rapid time controls but also for an enormous blitz workload. A longtime student of complicated middlegames and patient endgames, Martin mixes creative opening choices with stubborn, long battles that often run well past the 50-move mark — perfect material for highlight reels and coffee-fueled comeback stories.
Preferred time control: Rapid — where Martin often finds his best balance of speed and calculation.
Notable peaks (for context in prose): 2300 (2025-05-31) and 2563 (2025-09-25).
Playing Style & Strengths
Martin's chess is defined by endurance and resourcefulness. He tends to play long decisive games (average decisive length in recent years hovers in the mid-70s moves) and has an unusually high endgame frequency, often taking opponents into complex, technical finales.
- Endgame frequency: high — Martin converts small advantages and defends stubbornly.
- Tactical resilience: strong comeback rate and solid results after material losses.
- Typical game length: long — both wins and losses average around the mid-70s moves.
- Psychology: best time to catch Martin is around 17:00 — he’s sharp then (and slightly less so at 4:00 AM).
Analytics speak for themselves: Martin combines a patient positional sense with the tactical sharpness required to finish long games. Opponents often describe his games as “pleasantly exhausting.”
Openings & Repertoire
Martin's repertoire is eclectic and battle-tested. In blitz he favors classical systems and some offbeat gambits; in rapid he experiments with rare but effective sideline ideas.
- Ruy Lopez — a staple with a strong win rate in blitz (Ruy Lopez).
- Caro-Kann & Slav family — reliable choices that fit his positional, endgame-oriented approach.
- Pterodactyl/Modern ideas and even the occasional Diemer-style gambit to keep things spicy.
- Rapid-only surprises: Bird (Dutch Batavo Gambit) and other one-off lines where he boasts 100% mini-sample results.
Sample openings with strong blitz records: Caro-Kann Defense, Slav Defense, Diemer-Duhm Gambit (DDG): 4...f5.
Notable Streaks & Opponents
Martin has enjoyed streaks of dominance and the occasional slump — both part of the rollercoaster of serious online play.
- Longest winning streak: 9 games. Current winning streak: 1 game.
- Longest losing streak: 9 games (he bounces back).
Frequent opponents and head-to-head highlights:

Quick summary
Nice stretch of results — you’ve converted several games into decisive wins and your recent rapid win (vs 3fidak) shows clean tactical finishing and active piece play. Your opening choices are producing wins (Bird/Dutch lines, Pterodactyl, Gruenfeld line with Bg5 c6), but a recurring theme in the losses/draws is allowing counterplay and tactical shots from the opponent. Below are focused, practical suggestions to keep your momentum and plug the leaks.
What you’re doing well
- Finishing ability — your recent mate and forced tactics show you spot concrete endings and tactical motifs quickly. Example: the final sequence vs 3fidak finished very cleanly.
- Opening diversity — you use offbeat lines and traps effectively (e.g., Blackburne Shilling and Batavo Gambit when they work), which earns practical wins in quick games.
- Aggressive instincts — you play for the initiative and don’t shy from complications, which is a strong trait in rapid time controls.
Recurring weaknesses to fix
- Over-grabbing material without full calculation — in a couple of games you win a pawn or grab activity but then miss an opponent tactic (look at the game vs MaraPlzen where counterplay and a piece coordination problem turned the tables).
- King safety and coordination — when you open lines around your king you sometimes underestimate counterchecks and pins. Prioritize simple defending moves that remove immediate tactical resources of the opponent.
- Under-defended pieces — watch pieces left en prise or poorly defended after aggressive pawn grabs; train to ask “what is my opponent threatening?” before each capture.
- Time allocation — in rapid you benefit from a fixed checklist: check opponent threats, candidate moves, and immediate captures. Spend the first 10–15 seconds of each move confirming there is no tactic against you.
Concrete training plan (4 weeks)
Short, targeted practices you can do daily or every other day:
- Daily tactics (15–20 minutes): focus on puzzles that end with forks, pins, and back-rank themes. Aim for accuracy, not speed. Use mixed difficulty so you get pattern repetition.
- Blunder check routine (5 minutes): before every move in online games, run a three-question check — (1) Does opponent have a check? (2) Any captures on my last-moved piece? (3) Any strong enemy piece on my back rank or major file?
- One slow game per week (30+10): play one longer game and annotate it yourself before using an engine — practice deep thinking and defensive technique when under pressure.
- Opening consolidation (2 sessions/week, 20 min): pick your most successful lines (Bird/Dutch, Gruenfeld line you used) and build 3–4 typical middlegame plans and a couple of trap lines. Use Bird Opening: Dutch Variation, Batavo Gambit and Gruenfeld: 5.Bg5 c6 as anchors.
- Tactical calculation drills (2×/week): pick positions from your losses/draws and force yourself to calculate 3–5 moves deep before checking solutions — this builds the habit of not grabbing material too fast.
Actionable checklist before each game
- Set a target: “No hanging pieces” or “Don’t move the same piece twice in the first 8 moves” — pick one simple rule and enforce it.
- First 8 moves: prioritize development and king safety over material gains — only take a pawn if it is tactically sound.
- When up material: simplify if you can (trade down) and exchange into a winning endgame rather than keeping kings exposed.
- Endgame habit: if you reach a winning but technical endgame, slow down — convert responsibly (rook/king activity, passed pawns).
Study targets (short list)
- Tactics: forks, skewers, pins, discovered attacks, back-rank mates — drill these until spotting is automatic.
- Endings: basic rook endings and king + pawn vs king — these convert many rapid wins.
- Practical openings: keep the lines that bring you consistent results and study common response plans, not every sideline. Try to build 5–10 typical middlegame plans for your main systems.
How I can help next
If you want, I can:
- Annotate one loss and one recent win with concrete improvements and alternative moves (you pick which game).
- Create a 2-week micro-training schedule tailored to the openings you play most (I see strong results in your Bird/Dutch lines and Gruenfeld branch).
- Give a short tactical set based on motifs that have cost you games recently.
Next steps for this week
- Do 5–10 tactics daily focused on pins and forks.
- Play one 30+10 game and annotate it (find 3 moments where you could have improved your assessment).
- Review the loss vs maraplzen: ask “what did I miss in opponent’s reply?” and try to calculate the key line before checking.
Final note
Your recent rating rise and win streak show you’re improving fast — keep the tactical sharpening and add a little structure to your decision process. Small habits (the blunder-check, one slow annotated game per week) will preserve your gains and reduce avoidable losses.
Tell me which single game you want annotated first (I recommend the April 19 loss vs maraplzen or the May 31 win vs 3fidak), and I’ll do a focused post-mortem highlighting 3 concrete improvements.
