Oscar de la Riva (oskychess)
Grandmaster Extraordinaire & Bullet Blitz Boss
Oscar de la Riva, proudly carrying the Grandmaster title from FIDE, is not your average chess player. Known by the chess community as oskychess, Oscar brings both brains and a dash of humor to the 64 squares. If chess was a video game, Oscar would be the final boss you face after dodging a thousand pawns and knights.
With a peak bullet rating soaring to an impressive 2722 back in June 2021 and a blitz pinnacle of 2639 in late 2019, Oscar’s quick fingers and sharp mind make opponents break a sweat faster than you can say “checkmate.” His bullet games boast a solid 54.78% win rate over 4,100+ battles, and his blitz record is even more dazzling with a 56.21% win rate.
Playing Style & Personality
Known for his love of the endgame (engaged in over 85% of his games), Oscar is like a chess marathon runner who finishes strong while most others are gasping for air. He averages about 75 moves per win, showing persistence and patience that's a mix of a grandmaster’s finesse and a stubborn mule’s resolve.
Don’t be fooled though — his tilt factor is a casual 9, which means Oscar can handle a few bad moves without flipping the board... too often. His comeback rate is an astonishing 87.46%, proving that Oscar never throws in the towel until the king hits the ground.
Fun Facts & Stats
- Longest winning streak: 20 games (because, why not?)
- Favourite time to play: Bright and early at 8 AM when others are still dreaming about their openings
- Psychological secret weapon: An uncanny 52.86% win rate even after losing a piece — having a "bring it on" attitude in adrenaline-fueled scrap chess.
Recent Games
Oscar’s recent victories include a slick win by resignation against MartinoRC, showcasing classic Grandmaster depth and precision in what appears to be Bird's Opening territory. He can also snatch wins on time, proving that speed and cunning go hand in hand in his playstyle.
While every great has their off days, Oscar sometimes finds himself on the receiving end of a resignation from opponents like emateu26. But hey, even Magnus had tough mornings!
In Summary
Oscar de la Riva is a true Grandmaster in every sense — strategic, resilient, and sometimes delightfully mischievous on the chessboard. Whether blitzing through bullet games with lightning speed or patiently unraveling endgame mysteries, oskychess is a player to watch, admire, and perhaps occasionally challenge (if you dare).
Oscar, here’s a tailored training note based on your latest games (2639 (2019-11-05))
1. What you are doing very well ✅
- Ambitious openings. With Black you confidently choose the Modern Defense / Pirc structures; as White you vary between 1.e4 and the ultra-aggressive Bird's Opening. This keeps many opponents off balance and often gives you an early space advantage.
- Kingside initiative. In several wins (e.g. versus pepeveloso) you converted attacking chances with sacrifices on f7/f6 and swift queen–rook lifts. Your feel for mating nets is clearly above average.
- Dynamic pawn breaks. Timely strikes such as …d5 in the Modern and e5/e4 in your Bird games show you understand when to open lines for your bishops.
2. Recurring problems to iron out ⚠️
- Early queen adventures. Losses against Rebeca Jiménez Fernández and Esteve Mateu began when your queen hunted pawns (…Qxb2 / Qa3 or Qb6–b4) before development was complete. Consider the rule “three minors developed before the first queen sortie.”
- Light-square weaknesses in the Modern. Playing …Nh6–f7 and …c6 without …d6–e5 can leave d6 & e6 soft. Study model games by Kamsky & Radjabov in the Pirc to see how they reinforce those squares first.
- Time management. You often reach move-25 with <20 seconds. Many strong positions have slipped (see the resignation vs ST-Sandavagur) because you ran out of calculation time. Adopt a simple 20-40-20 rule: spend 20 % of the clock on the first 10 moves, 40 % from move 11–20, and keep 40 % for the rest.
- Technique in won endgames. The win vs Pedragerd was won on time, yet the rook-pawn ending was still tricky. Drill basic rook endings (Lasker, Lucena, Philidor) 15 minutes/day for a fortnight.
3. Concrete opening tweaks 🛠️
| Your move | Upgrade to study |
|---|---|
| Bird: 5.Nh3 & 8.Nf2 | Try 5.Nf3! & 6.c4, the “Larsen-Kasparov” setup – keeps quicker pressure and cuts …e5 ideas. |
| Modern: …Qb6 vs 4.Be3 | Replace with 4…a6 5.Qd2 b5!? (the “Tiger Modern”) – safer queen, same counter-punch. |
| Pirc vs 4.f4 | Study the plan …c5 & …d5 in one go (Carlsen-style) instead of the slower …Nh6–f7. |
4. Tactical workout of the week 🧩
Set up the position after 17…d5 in your win against pepeveloso:
Try to find both the best defensive move for Black and the fastest mate for White. Limiting “one-move optimism” will save you half a point each session.
5. Two-week action plan 📅
- Review each loss with engine, but spend twice as much time asking “
what was my decision-making process?
” as you do hunting tactics. - Play five 10|0 games this weekend – same openings – focussing only on king safety before pawn grabs.
- Daily routine: 10 mins tactics, 10 mins rook-endgame drill, 5 mins visualisation (boardless replay of your most recent win).
Keep the creativity, but anchor it with a touch more discipline and you’ll push into the next rating bracket very soon. 💪
