Alvin Hernandez: The Top Secret Chess Enigma
Alvin Hernandez, known in the chess world by the mysterious handle codezt, is a blitz and bullet enthusiast whose games resemble thrilling spy novels — packed with secret strategies, unexpected comebacks, and nail-biting finishes. With a peak blitz rating flirting with 1982 and a bullet max of 1791 back in 2014, Alvin is the kind of player who thrives under pressure — even if his opponents don't always know what hit them.
He’s battled over 3,500 blitz games, boasting a nearly even split between wins and losses, but his never-say-die comeback rate of over 92% means he’s the kind of competitor who refuses to fold early. Expect epic endgames here: Alvin’s games often extend to an average of 76 moves per victory, proving patience is his secret weapon.
Some of Alvin’s most frequent sparring partners include redmay63, yamilk, and paulleon, though his win rates against them suggest he enjoys a good challenge almost as much as a good joke.
Fun fact: his opening of choice is classified as "Top Secret" — and with a win rate just shy of 48% in blitz and a smidge over 50% in bullet, perhaps the world will never know exactly how he pulls it off! But if you face him, beware — Alvin sometimes wins with a sly grin and a series of moves that could only be described as chess ninja tactics.
Off the board, his tilt factor is low (12%), which means when Alvin loses, he bounces back faster than a knight jumping from square to square. And speaking of knights, his opponents might feel like they're caught in a relentless tactical whirlwind, given his perfect win rate after losing a piece.
In short, Alvin Hernandez is a tenacious, clever, and sometimes unpredictable chess player who mixes solid technique with a dash of mystery. Online or over the board, he's ready to put your king in check — and probably make you smile while doing it.
Hi Alvin!
You’ve shown some sharp tactical prowess and a willingness to seize the initiative, but a handful of recurring patterns are costing you points. Below is a concise performance review followed by concrete training ideas.
What you’re already doing well
- Fighting spirit & tactical eye. In your last win (see mini-diagram below) you punished 6…Qxd3 with the precise sequence 7.Bxd3 Bxd3 8.Qxd3, steering the game into a winning queen-vs-minor-piece endgame.
- Openings that create imbalances. You’re comfortable with unorthodox systems such as the Tennison Gambit and the King’s Fianchetto, which often drag opponents out of book early.
- Practical speed. Your moves come quickly; you rarely fall massively behind on the clock in 1|0 and 5|0 games.
Key areas to tighten up
-
Early queen adventures.
• In the recent loss 1.e4 c5 2.Nf3 d6 3.d4 a6 4.dxc5? Qa5+ (see PGN below) your queen picked up a pawn but invited a decisive tactical refutation.
➜ Guideline: Capture in the centre only when you are at least as well developed as your opponent. -
King safety vs. pawn storms.
Your Sicilian positions with …g6/…b5 tend to leave dark-square holes (e.g. 25.Qg2 in the A45 loss). Work on coordinating your fianchetto bishop with nearby pawns before launching flank breaks. -
Defensive calculation.
A number of defeats featured mates on the back rank or along the dark squares (…Qxh2#, …Qh1#). Spot the opponent’s forcing moves first, even when you’re on the attack. -
Endgame conversion.
Winning positions sometimes drift when you push pawns without activating the king. Convert one advantage at a time: first centralise the king, then advance your majority. -
Clock management in critical positions.
Blitz games you lost on time arose in tense endings. Allocate extra seconds when many pieces come off the board—your opponent’s threats are easier to spot, but one slip costs the full point.
Training menu for the next four weeks
- Daily 10-minute puzzle rush, focusing on mate-in-two and fork motifs.
- Play two rapid games (15|10) per week and annotate them; identify one moment you calculated your line but not their reply.
- Memorise one classical main line for each colour: e.g. White – Italian (Giuoco Piano); Black – Sicilian Scheveningen. Depth: first 10 moves only.
- Endgame drill: king + pawn vs. king races until you can recite the square rule in your sleep.
