Jonás Mejia (aka MrJhon18)
Jonás Mejia, better known in the chess universe as MrJhon18, is a player whose journey resembles the unpredictable dance of a knight: sometimes leaping ahead brilliantly, other times bouncing sideways in curious fashion. With a peak rapid rating of 782 achieved in January 2022 and a bullet peak of 767 in April 2025, Jonás has shown flashes of serious tactical acumen and resilience.
Style & Strategy
Known for mixing classic openings with a dash of adventurousness, Jonás enjoys testing opponents with the Queens Pawn Opening and various Zukertort variations. His trusty Englund Gambit in rapid games boasts a respectable win rate near 60%, proving that sometimes taking risks pays off—though equally often it leaves spectators biting their nails.
Drawing games isn’t Jonás’ favorite pastime—he prefers a fight to the bitter end, reflected in only 3% draws overall. And when things get tough, his comeback rate stands an impressive 67.3%. If he loses a piece, you can bet he’s still plotting a comeback on the board.
Notable Statistics & Quirks
- Average decisive game length hovers around 49 moves, so Jonás likes to keep things engaging without dragging endlessly.
- His most successful day of the week? Sunday, with a robust win rate of nearly 58%.
- Surprisingly, Jonás plays his best chess at 1PM, his “best time of day” for calculated chess sorcery.
- He has a slightly higher success with playing White (~50% wins) compared to Black (~45%), but don’t let that fool you — MrJhon18 can sling some serious Black pieces too.
- Though the Blitz ratings can be a rollercoaster ride (dropping at times), his lasting love remains Rapidity, where his skill truly shines.
Recent Drama from the 64 Squares
In one of his latest rapid showdowns, Jonás executed a classic Giuoco Piano - Giuoco Pianissimo checkmate maneuver, proving his opening preparation can pay off beautifully:
1. e4 e5 2. Bc4 Nc6 3. Nf3 Nf6 4. O-O Bc5 5. d3 d5 6. exd5 Nxd5 7. d4 exd4 8. Re1+ Nde7 9. Bg5 O-O 10. Bxe7 Nxe7 11. Ng5 Re8 12. Bxf7+ Kh8 13. Qh5 h6 14. Bxe8 d3 15. Qg6 Nxg6 16. Bxg6 Qxg5 17. Bxd3 Qf6 18. Re8+ Bf8 19. Nc3 Bf5 20. Rxa8 Bxd3 21. cxd3 Kh7 22. Nd5 Qxb2 23. Rf1 Bd6 24. h3 Qxa2 25. Re1 Qxd5 26. Ree8 Qxd3 27. Rh8+ Kg6 28. Raf8 Qd1#
It’s fair to say when MrJhon18 is in the zone, checkmates come quicker than a coffee break.
Fun Facts
Jonás has an early resignation rate of about 14%, which means sometimes the battle gets too spicy, and he’d rather unplug and save the energy for the next game. But never question his spirit after a loss — his tilt factor is kept low at 9, so he bounces back like a true chess phoenix rising!
Challenges & Rivalries
Even the best stumble. Jonás has faced tough losses against players like antho3512 and lenamagda44, but keeps a perfect 100% win record against several opponents including elcaturgg and stormtrooper125. The opponent list reads like a chess soap opera: fierce battles, heated wins, and occasional heart-stopping blunders.
Current Status
As of mid-2025, Jonás is actively refining his craft, especially in the rapid time control where his average game complexity and tactical awareness continue to evolve. Whether winning by quick checkmate or grinding through a tough endgame, this player turns the 64 squares into a stage for drama, strategy, and occasional joyful chaos.
Keep an eye on MrJhon18—a chess profile that mixes classic strategy with moments of inspired flair and unpredictability. Just don’t blink, or you might miss the next tactical gem!
