Fun Fact
Despite an aggressive approach, he doesn’t resign lightly — almost as if his pieces have a secret pact, holding on until the last pawn drops. Just like a true CubanKnight, he knows when to hold steady and when to attack like a knight on a mission!
Ignacio Perez — blitz improvement plan
You’ve shown a solid willingness to fight in sharp positions and to press when your opponent makes mistakes. In blitz, two big levers often separate steady performers from regular winners: time management and clarity in the middlegame plan. The goal here is to keep your initiative, but stay calm enough to pick simpler, safer routes when the clock is tight.
What you’re doing well
- You enter dynamic, tactical positions with confidence and look for active, forcing ideas that put pressure on your opponent.
- When you find a concrete plan or tactic, you tend to push through with energy and create practical chances.
- Your openings show you’re capable of reaching reasonable middlegame structures and keeping the position fluid rather than being immediately overwhelmed by a solid defense.
Key improvement areas
- Time management under pressure: in recent games you spent a lot of time in critical middlegame phases. Develop a two-pass approach: first, quickly discard obviously bad moves and identify a small set of credible candidate moves; then spend deeper lookahead only on those candidates. If your clock is slipping, switch to safer, more straightforward plans.
- Simplifying when ahead or in unclear positions: in blitz, it is often safer to steer toward simpler structures with clear plan for the next phase (development, king safety, and basic pawn structure) rather than chasing multiple tactical lines.
- Endgame awareness: many blitz losses come from not converting or misplaying rook/queen vs rook endgames or pawn endgames. Build a few core endgame patterns (rook endings with pawns on one side, opposition king fights, etc.).
- Pattern recognition and toolkit: strengthen quick recognition of common motifs such as back-rank threats, pins, forks, and typical middlegame plans after you develop your pieces. This speeds up decision-making in blitz.
Practice plan — next 2 weeks
- Daily quick-fire puzzles: 10–15 minutes focusing on tactics that emphasize short combinations and creating threats without deep calculation.
- Blitz practice with a timer: play short sessions (3+0 or 5+0) to train making good, fast decisions; after each game, note one thing you could have done faster and one safer alternative when you were short on time.
- Endgame drills: dedicate two short sessions per week to rook endings and simple king-and-pawn endings to improve conversion under time pressure.
- Opening consolidation: choose 1–2 openings you’re comfortable with for White and Black, and study the typical middlegame plans in those lines so you can recognize the right plan quickly in the moment.
Opening repertoire guidance
Your results across several defenses suggest you can benefit from a compact, pragmatic repertoire that emphasizes solid development and quick activity over deep, theoretical lines. Consider pairing a steady Black setup with a White plan that avoids overly sharp lines unless you’re prepared to navigate them on the clock.
- Adopt 1–2 solid Black defenses (for example, a flexible, classical setup) that lead to clear middlegame plans and straightforward piece development.
- For White, select a simple plan such as quick central pawn advance with solid development and controlled king safety, avoiding overly long theoretical branches in blitz.
- Keep a short list of “go-to” middlegame ideas in each chosen opening so you can act quickly rather than re-evaluating from scratch every move.

Next steps — actionable targets
- Establish a reliable pre-move-free routine: decide on a plan within the first 15 seconds of the game, then spend the rest of the early moves quickly and prosaically to reach a solid middle game.
- Pick 2 openings to master over the next few weeks and study the standard middlegame plans in those lines so you recognize the right pawn breaks and piece maneuvers quickly.
- In your next few blitz sessions, review at least one endgame conversion from each game and identify where you could simplify sooner to avoid/time pressure losses.
