Profile: William Christensen (Willi7)
William Christensen, known in the chess world by his fierce username Willi7, is a blitz maestro with a flair for putting pressure on opponents faster than you can say "checkmate!" With a peak blitz rating soaring to an impressive 2538 in April 2025, Willi7 has climbed the ranks from casual 1000-level games to the razor-sharp edge of chess elite.
Playing History & Style
Starting out modestly in 2012 with a blitz rating just over 1000, William rapidly ascended the ranks, surpassing 2000 by late 2016 and cracking the 2300 mark by 2021. His love affair with the Blackmar-Diemer Gambit is well-documented, reflecting his aggressive approach to the game—he's not one to shy from wild, tactical fights.
Known for his enduring stamina, Willi7 averages over 64 moves per win, and despite enduring some long losses averaging 78 moves, his comeback rate of nearly 90% demonstrates undeniable resilience. He's the kind of player who fights tooth and nail until the very end, refusing to resign early (his early resignation rate is a mere 0.32%).
Favourite Openings
- Queens Pawn Opening Blackmar-Diemer Bogoljubov Studier Attack — With over 720 games played, boasting a striking win rate of almost 58%. If you dare face it, prepare for some serious fireworks.
- Queens Pawn Opening Blackmar-Diemer Teichmann Variation — A favorite weapon with a solid 57% win rate from some 1280 battles.
- King's Pawn Opening King's Knight Elephant Gambit — Nearly 700 games with a winning tendency, showing his penchant for tactical melee.
Recent Games
Willi7’s recent victories showcase some clever finishes, including a delightful checkmate against SnipyJulmy in June 2025, where precision and timing combined to sweep the board clean. Not one to be easily defeated, though, recent defeats often come on time—a testament to his blitz battles being as intense as a roller coaster ride.
Playing Hours & Psychological Insights
Oddly enough, the best time for Willi7 to play is at 4 AM—probably when the rest of the world is asleep and he’s plotting his next tactical masterpiece. He enjoys the fiercest duels around 8 to 10 PM, a prime time where his win rates peak. However, like any human, he isn't immune to the dreaded chess tilt (rated at 14), so watch out if he's having a rough session!

Overview of recent bullet play
You’ve shown a willingness to engage in sharp, attacking lines and to try active pieces in fast games. The data suggests you perform well in aggressive openings like Amazon Attack, and you’re comfortable entering dynamic positions where both sides have chances. To keep improving, focus on converting that tactical energy into consistent, clean decisions under time pressure.
What you’re doing well
- Taking the initiative with aggressive openings. Your results in Amazon Attack and other active setups show you can press from the start and create practical winning chances.
- Willingness to complicate in the middle game. You don’t shy away from tactical skirmishes, which is good for bullet where hard-to-calculate lines often decide games quickly.
- Using piece activity to compensate for material imbalances. When you get your pieces into aggressive squares, you put pressure on the opponent’s position and keep drawing chances into the game.
Areas to improve
- Time management in bullet. When the clock is tight, it’s easy to miss simple defensive moves or overextend in attacks. Build a quick, repeatable decision process to avoid getting overwhelmed by forcing lines.
- King safety and early structural decisions. In fast games, it’s tempting to go for a flashy tactic, but neglecting safe development or king safety can backfire. Prioritize solid development and timely castling.
- Endgame conversion. If a position simplifies, resist chasing every tactical shot and focus on clear, practical endgames. Practice common rook-and-pawn endings and simple minor-piece endings so you can convert advantages reliably.
- Opening consolidation. You experiment with several openings, which is great for versatility, but bullet benefit comes from depth. Pick 1-2 openings you like (with White) and learn the typical middlegame plans and key pitfalls so you can play with a clear plan under time pressure.
Targeted plan to level up
- Time-boxed practice routine: 15 minutes of tactics daily (focus on forcing moves and checks), 15 minutes of endgames twice a week, and 1 short game review session daily to identify the big blunders you’re making under time pressure.
- Standardize a White repertoire: commit to one aggressive line (such as Amazon Attack) and learn the core middlegame plans, common pawn breaks, and typical piece maneuvers. This reduces guesswork in bullet and increases consistency.
- Endgame habit formation: after each game, quickly note whether you ended in a rook ending, opposite-colored bishops, or a straightforward king-and-pawn ending. Then study a couple of simple techniques for those endings.
- Review with focus: when you lose or draw, write down the top three critical turning points and ask, “Was there a safer alternative that would preserve equality or a clear plan to win?”
Openings performance snapshot and practical advice
Your openings show strong results with aggressive, dynamic lines (notably Amazon Attack) and solid performance in several other systems. To translate that into more consistent gains, consider the following: - Pick 1 White and 1 Black system to rely on in bullet sessions. Learn the main traps and the typical middlegame plans for those lines. - For White, map out the first 8-10 moves in your chosen Amazon Attack line and memorize the common pawn structures that result, so you can steer into familiar middlegames even when you’re short on time. - For Black, identify a couple of reliable responses to White’s main 1.e4 move that you’re comfortable with, so you can keep positions manageable instead of entering overly chaotic battles.
Sample 1-week practice plan
- Daily: 15 minutes of tactical puzzles focusing on checks, captures, and forcing moves.
- 3 days this week: 1 structured bullet game against a quick opponent, with post-game notes focusing on one strength and one improvement area.
- 2 days this week: endgame drills (rook endgames and simple pawn endings) for 15 minutes each.
- Weekend: review one of your recent loss games without engine, write down the key turning point and a safer alternative line, then replay that portion to confirm the improvement.
Optional note
If you’d like, I can tailor a 2-week micro-plan based on the openings you prefer, and generate a small, private practice Pgn set to work through specific positions from your recent games. This can help you track progress and stay on a steady improvement path.
