Active Chess vs Sealed Move

Playing chess regularly develops human cognitive abilities, such as: logical thinking, attentiveness, memory, ability to analyse and plan. However, in classical chess there is one drawback that does not contribute to the interest in the game on the part of millions of potential players. For thousands of years of the existence of chess, all combinations, the so-called openings, that can appear on the chessboard at the beginning of the game, have been developed and well studied. A professional player who knows several of these openings will certainly gain an advantage over an ordinary player, even if his cognitive abilities are obviously lower. Active Chess got its name because it excludes the use of different preliminary preparations in different game situations, especially at the beginning of the game. In active chess, there is no well-known traditional arrangement of pieces, and this precludes the use of a library of openings. From the first moves of the game, an active game begins, the result of which depends on the player's cognitive abilities, his ability to think and a bit of luck. The luck factor is associated with the formation of the starting position randomly for each player. But in order not to depend on capricious luck, the player can independently form his position on the board. At the same time he does not know what position his opponent will have. This gives a special sharpness of the game. In Active Chess, almost all the rules of classical chess are followed with a few exceptions: • Rule for castling of kings is absent since a player, when creating an initial position, can place his king in that part of the board and among other pieces, where he will be in the greatest safety. • Chess pieces can be placed on the first three ranks of each side in the order that suits the player. • A special mark is applied to the image of the pawns of the first move, which disappears after the first move. • Bishops can be of the same color field or different color fields at the choice of the player. Active Chess has to a choice of two options for boards 8x8 and 8x10. In the current version of the application, only a game with a chess bot is available. The application has ads are shown after the end of the game. The winner does not see ads! You can remove all Ads and limit of preset positions by subscription. Enjoy Game!

Sealed Move is a chess coach on your phone. Stockfish makes every factual claim about your game, and a coach who talks like a person turns those claims into plain speech. The coach never analyzes the board on its own, which means it cannot invent a variation. THE ENGINE JUDGES. THE COACH EXPLAINS. Every evaluation, best move, tactic, and opening name comes from the engine. The coach's job is the words: what your move accomplished, what it missed, and what deserves your attention now. When the game genuinely shifts, the coach steps in with a short recap of the moves that caused the swing, then leaves you to play. FEEDBACK THAT WAITS ITS TURN Coaching arrives as cards docked under the board. Read the newest at a glance, tap to expand it, and swipe back through earlier notes whenever you like. Ask a question and a full conversation opens; close it and the board is yours again. TAP THE COACH'S WORDS Every square, piece, and move the coach mentions is live. Tap f7 and the board shows you f7. Tap a move and an annotation pen draws the same red arrow a coach reaches for at a demo board. A LEXICON WITH MOVING PARTS When the coach names a fork, a skewer, or a Najdorf, the word links into a Lexicon of 153 entries: a plain definition plus the pattern played out on an animated board. Every demo line was checked by the engine before it shipped. HINTS THAT LEAVE THE FIND TO YOU Stuck in a sharp position? The coach will tell you what kind of idea you are missing and let you find it. The eval is the engine's, the nudge is the coach's, and the find is still yours. REVIEW THE GAME AS A TIMELINE After the game, the review lays your moves on a scrubber with a dot at each moment that mattered: green where the game swung your way, red where it slipped. Press play and the coach walks you through the moments, two moves of run-up at a time, at reading pace. EXPORT THE GAME AS A VIDEO Turn any finished game into a vertical video. The moves play out on the board with the coach's red arrows or classic highlights, and the coach's notes hold on screen at reading pace. Trim the clip to the stretch that decided the game, then share it or save it from the share sheet. SCAN A BOARD Photograph a puzzle from a book, a newspaper, or a screenshot. Sealed Move reads the position right on your phone, nothing is uploaded, and puts it on an editable board so you can fix any square. Then play it out, have the coach solve it, ask why the key move works, or export the solution as a video. AN OPPONENT WHO PLAYS LIKE A PERSON Practice games run against Maia, a neural network trained on millions of human games, so your opponent misjudges positions the way people do.

OPEN WHERE IT COUNTS Sealed Move embeds Stockfish 11 under the GPLv3 and honors the license fully: the complete client source is public at github.com/tjameswilliams/sealedmove-app, tagged for every release. The claim that the coach cannot invent a line is one you can audit. The name comes from the adjournment era, when a paused game meant sealing your next move in an envelope and going home to analyze. Secret preparation, deep analysis, the resumed game: that is what your coach does between your moves.
