Are you able to solve chess puzzles but struggle to find those same tactics in your own games? Or are you simply looking to improve your tactical awareness? Then Chess Pro Trainer is for you. Chess Pro Trainer is unlike any chess training app available today. It is designed to improve your tactical vision, calculation, pattern recognition, and overall chess strength through realistic in-game simulation training. Most puzzle apps teach you HOW to solve tactics. Chess Pro Trainer teaches you HOW and WHEN to look for them. In traditional puzzle apps, you know a tactic exists before you make your first move. In real games, nobody tells you a tactic is there. Chess Pro Trainer recreates that experience by presenting positions from real games where tactical opportunities may appear immediately or several moves later. This creates a realistic training environment that directly improves practical over-the-board and online play. The app also features an advanced Alternate Acceptable Move system. Rather than simply marking moves right or wrong, users can earn credit for finding Valid, Equal, or even Better moves than those played in the original game. This rewards creativity, strong decision-making, and deeper calculation. CORE TRAINING MODULES • Tactics Recognition Training Train both tactical awareness and tactical calculation through a unique two-phase training system. • Genius Training Develop attacking instincts through aggressive sacrifice positions and high-level tactical play. • Checks Training Master the ability to identify every possible check in a position. • Coordinated Squares Training Learn to recognize key action squares that often serve as the foundation of powerful tactics. • Unprotected Pieces Training Develop the ability to identify vulnerable pieces using a deeper definition of what "unprotected" truly means. ADDITIONAL FEATURES • Stockfish-powered Analysis Board • Global Leaderboards • Detailed Statistics Tracking • Multiple Difficulty Levels • Board Themes and Sound Customization • Learning Coordinates Module • Random Position Generator • Regular Content Updates Whether you are a beginner or an advanced player, Chess Pro Trainer provides a focused and efficient way to improve your chess skills through realistic tactical training. This is not just another puzzle app. This is a complete tactical training system. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
