About D O (aka deemmy)
D O, known online as deemmy, is a steadfast chess player whose journey through the 64 squares has been marked by perseverance, tactical flair, and a slightly selective memory—at least when it comes to victories!
Rating Rollercoaster
Since first appearing on the scene in 2014, deemmy has danced through the rating boards with a bullet peak rating of 1766, blitz mastery reaching an electric 1878, and rapid peaks of nearly 2000. Daily chess is no stranger either, with a respectable personal record peaking at 1572. If ratings were a rollercoaster, deemmy enjoys the thrilling ups and challenging downs, navigating them all with characteristic resilience.
Playing Style & Psychology
A true warrior on the board, deemmy is known for an early resignation rate (sometimes saving energy for the next game) of about 7%, but battles through endgames with a universe-best endgame frequency of 69%. Don’t be fooled by the conservative early quits—they are more strategic retreats than surrender flags.
What really sets deemmy apart is the comeback rate of 84%, proving few can keep them down for long. Even after losing a piece, deemmy keeps fighting with a near 50% win rate, showing true fighting spirit.
With a tilt factor at a reasonable 15%, deemmy keeps cool enough to avoid nasty rage quits—though sometimes a four-move checkmate (like the recent stylish win with the Caro-Kann Panov) keeps the adrenaline pumping.
Favorite Openings
Deemmy adores the Caro-Kann Defense, rattling opponents over 2,300 games with a consistent win rate above 52%. Other preferred lines include the London System and the Philidor Defense, each lending a dash of classical solidity and modern aggression. Fun fact: deemmy’s “Undefined” opening is something they could improve on—a modest 16% win rate there!
Notable Stats & Habits
- Longest winning streak: 16 games (imagine the caffeine consumption!)
- Current winning streak: Still going strong at 4
- Longest losing streak: 15 games—remember, even champions have their dark days!
- Best time to strike: 7 AM sharp—morning coffee and early checkmates, anyone?
Recent Glory
In a recent bullet battle, deemmy triumphed by checkmate using their signature Caro-Kann Panov Modern Defense, stunning opponent harshjaiswal966 in a blistering display of tactics and timing. The game ended at move 31 with a rook delivering the coup de grace.
The Opponents
Among the crowd of challengers, deemmy faces a regular cast including the likes of zrom, oscarcorvill, and masspro. Their win rates vary wildly, but the player consistently shows grit and humor in the face of all comers.
Summary
Whether it’s blitz, bullet, rapid, or daily play, deemmy brings a delightful mix of strategic patience and tactical savagery. Their love for the Caro-Kann, ability to bounce back from setbacks, and penchant for timely victories make them a true force and a gamer to watch.
One might say: deemmy is that friend who sometimes quits early, but always comes back for one more game—and usually leaves you checking your king. Put simply, chess’s not just a game for deemmy; it’s a way of life, a dance of knights, and a quest for that perfect checkmate, preferably before breakfast.
Quick review of your most recent win
Nice game — you turned an aggressive kingside build into concrete threats and pressured until your opponent flagged. Below is a small interactive replay of the critical phase; review it and try to spot the turning points before reading the notes.
Opponent: D O
What you're doing well
- You create kingside attacking chances consistently — advancing h and g pawns at the right moment paid off here. That aggression is a real practical weapon in blitz.
- Good queen activity and willingness to trade into favorable lines — you used checks and queen invasions to keep the enemy king on the run.
- You're comfortable with open, tactical positions (Sicilian / open games). You find forcing continuations and spot tactical motifs quickly.
- Your opening choices give you rich middlegame plans rather than dry positions — that helps maximize practical chances in short time controls. See: Sicilian Defense.
Main areas to improve
- Time management: you won on time in the latest game — still, large clock swings (or relying on flags) can hide weaknesses. Practice keeping 10–20 extra seconds in complex positions so you can calculate critical variations without panic. See Time pressure.
- Watch for counterplay after an attack. In the game your opponent managed knight jumps (Ne3 / Nxg2) that could have created trouble if you weren't precise. Before launching, scan for opponent counterthreats.
- Defensive pattern recognition — back-rank and mating nets can appear quickly when the king is driven around. Train common motifs (e.g., Back rank mate) so you spot both threats and resources faster.
- Avoid leaving pieces hanging when going for the attack. Quick wins are great, but “loose” pieces are exploitable in faster time controls — a quick check for any Loose Piece before you move helps.
- Endgame technique: once you have an advantage, simplify into an endgame you know how to convert. Practicing a few key rook and queen endgames will increase your conversion rate.
Concrete study plan (4 weeks)
- Week 1 — Tactics sprint: 20 minutes daily of mixed tactical puzzles (forks, pins, deflections). Do them with a short pause to actually calculate before checking the solution.
- Week 2 — Practical blitz with goals: play 10 blitz games where your only goals are (a) keep 15s+ on the clock, (b) never leave a piece en prise, (c) decide: trade or attack? After each game, annotate 2 mistakes.
- Week 3 — Endgames & simplified positions: study Lucena/Rook vs pawn scenarios and basic queen+pawn endgames; spend three 30-minute sessions converting simple material advantages.
- Week 4 — Opening plans & traps: pick the 2 Sicilian/King-side lines you play most. Drill typical pawn breaks, piece placements, and one tactical idea from each. Use an engine only to verify, not to find your moves first.
Blitz checklist (use during games)
- Before you move: 1) Any immediate checks or captures for either side? 2) Are any of my pieces Loose Piece? 3) Does this move create counterplay for the opponent?
- Keep a simple strategical compass: king safety > piece activity > material (unless you win material cleanly).
- When ahead materially: trade pieces (not pawns) and simplify toward an endgame you know.
- When low on time: reduce risk — avoid speculative sacrifices and rely on safe, forcing moves if possible.
Short practice tasks (10–30 minutes each)
- 10-min tactics: focus on puzzles that end with winning material rather than mate-in-one repeats.
- 15-min review: pick one loss and one win from your recent blitz and annotate where the position changed — write 2 alternative moves and why.
- 30-min thematic blitz: play 3 games where you always castle long and try to storm the kingside (practice the plans you used successfully).
One actionable tip for your next game
When you open the h-file (h4–h5–hxg6 sequence), pause and check whether a rook or queen invasion will be available after the exchange — if yes, push. If the file collapses or the opponent gets knight jumps into e3/d3, consider forcing trades first. That small habit reduces counterplay and increases conversion chances.
