- IN QUESTA VERSIONE (4.8.4) • Corretto un errore che causa un comportamento anomalo dell'applicazione nella parte dei dati delle partite. • Corretto errore che si verificava nella gestione delle impostazioni dell'applicazione. • Correzione di errori minori, miglioramenti e ottimizzazioni. - PRINCIPALI CARATTERISTICHE INTRODOTTE NELLE ULTIME VERSIONI • È stata integrata la nuova versione del motore Stockfish 18 con il supporto delle Reti Neurali (NNUE). Secondo gli autori, Stockfish 18 mostra un miglioramento costante nelle prestazioni, con un guadagno Elo fino a 46 punti. • É ora disponibile un Database Unico online composto da più di 11 milioni di partite. Oltre alla normale consultazione è possibile fare delle ricerche mirate per dati o per posizione. Il Database Unico sarà aggiornato regolarmente. • Aggiunta la possibilità di effettuare ricerche in un Database basate sui Tag PGN (Eventi, Date, Bianco, Nero, ECO, Elo etc). Si accede a questa sezione dal Menu principale. • Riconoscimento Diagrammi:questa funzionalità permette all’utente di scattare e/o caricare foto di diagrammi scacchistici e convertirli in posizioni in formato PGN. È possibile caricare immagini che contengono più diagrammi di scacchi. • Dalla sezione Aiuto si può scaricare la descrizione completa dell'applicazione che è stata aggiornata. Si può consultare la stessa descrizione al seguente indirizzo: https://chessstudio.wordpress.com/chess-studio-2/. • Chess Studio si arricchisce di una nuova funzionalità: la possibilità di consultare un Database di partite OnLine suddiviso per Anni e per Tornei a partire dal 1560. Questo grande Database OnLine sarà aggiornato quotidianamente con nuovi Tornei e nuove Partite. L'accesso a questo Database prevede il pagamento di un abbonamento Premium simbolico. • È stata aggiunta una nuova funzionalità di allenamento: l'utente può caricare una partita da un database e decidere se muovere al posto del Bianco o del Nero senza vedere le mosse per valutare le sue capacità. Alla fine verrà prodotto un rapporto che ripercorre l'intera sessione di allenamento. É possibile utilizzare questa funzionalità sia scegliendo la partita con cui allenarsi sia lasciando decidere all'applicazione la partita in modalità casuale. Per l'utilizzo di questa funzionalità sono possibili alcune impostazioni mediante un'appropriata interfaccia. Ci sono vari modi per accedere a questa funzionalità, ad esempio dal menu in alto al centro nella schermata con la scacchiera. • Chess Studio è ora in grado di leggere i Database in formato ChessBase. Può importare i formati cbh, cbp, cbt, cbg, cba, cbs e cbc. • È stata inserita una nuova sezione dedicata all'allenamento. Al momento è possibile risolvere una serie di puzzle tratti da partite giocate principalmente on-line. Si tratta di puzzle adatti a tutti i giocatori. • Possibilità di scegliere tra diverse disposizioni della scacchiera sullo schermo a seconda delle esigenze dell'utente. Per chi utilizza Chess Studio sull'iPad questa funzionalità permette di scorrere le mosse di una partita con un tap a destra o sinistra della scacchiera. • Possibilità di giocare online utilizzando la piattaforma Lichess. Per giocatori non vedenti o ipovedenti questa funzionalità è completamente supportata dal Voice Over. • Inserimento automatico nelle partite dell'analisi del motore toccando l'analisi del motore. • Dalla sezione aperture di un database è possibile salvare in un nuovo database le partite relative ad un singolo codice ECO o ad una singola variante di apertura. Per poter far ciò basta strisciare verso sinistra sulla variante di apertura che si vuole salvare e seguire le indicazioni.

ECCEZIONALE

Database incredibile. Tutti i tornei e tutti i giocatori a portata di mano *****

Crazybishop2025-01-25

★★★★★

Parrebbero esserci potenzialità …

Appena scaricato. Ad un primo approccio non sembra troppo intuitivo. Sto cercando un modo per importare database .pgn, ma non riesco. Ho cercato di non n isee una mail per chiedere delucidazioni, ma la app mi informa che non ho impostato la mia mail. Nelle impostazioni pare non ci sia modo di impostarla … Vediamo se riesco a venirne a capo 🤷🏻‍♂️

Di gran lunga la migliore !

Una meraviglia. Continuamente aggiornata e migliorata! Tutti i complimenti del mondo allo sviluppatore e ancora grazie per questo gioiello !

Ottima applicazione

Se ci fosse la possibilità di sincronizzarla tra dispositivi diversi sarebbe perfetta!!!

La migliore app per studiare scacchi con iOS

Raramente si trovano app che da sole giustificherebbero l’acquisto di un iPad, e Chess Studio è una di quelle. Se volete studiare seriamente gli scacchi con l’ausilio di un iPhone o iPad, questa è l’app che state cercando! Permette di creare, gestire, annotare, commentare, illustrare database di centinaia di partite. Supporta la creazione di libri di aperture e importa quelli di Chessbase, e la creazione di partite e varianti a partire da questi. Importa qualunque partita da PGN Mentor, e importa anche le partite uscite su This Week in Chess e sul Messaggero Scacchi per essere sempre aggiorna

Applicazione veramente ben fatta e con gestione dei pgn davvero completa. Ottima!

Ottima app

Ottima app ce l’ho sua qui che su mac con icloud registro le mie partite e le rivedo sul mac bravo spero che non abbandonerai mai l’app come fanno la maggior parte dei sviluppatori quando passano gli anni grazie

Pepeppe2019-06-09

★★★★★

Applicazione molto bella e molto facile da utilizzare

È l’applicazione più accessibile che io conosca degli scacchi, con il Voice over si può allenarsi anche al buio, legge tutto quello che è nell’applicazione , ottima anche per chi non vede o vede poco. Ottima per allenarsi, vedere libri di aperture, partite in pgn.

Finalmente qualcuno l’ha creata!!!

Rarissimamente scrivo recensioni ma il sig. Giordano la merita tutta! Ho cercato un’alternativa a Chessbase (che purtroppo esiste solo per Windows) per molto tempo e avendo io un Mac non avevo la possibilità di gestirmi i miei database sul mio Mac Book e sul mio iPad. Oggi ho FINALMENTE trovato questa app che risolve tutti i miei problemi scacchistici. Funziona esattamente come Chessbase e anzi ha anche delle opzioni in più! La uso da poche ore e devo dire che mi ha veramente stupito. Sig. Giordano Le faccio veramente i complimenti per aver pensato a tutto! Credo non abbia più bisogno di aggio

Marinevil2018-02-21

Top app!

Giordano is a very hard worker!! He created a marvelous app for the analysis and the editing of PGN files. He is also very kind and answers readily on Facebook if you need any support! I love this app, and I am looking forward to a possible OCR feature for scanning positions. Thank you very much for your passion.

Top App

Ottima e completa applicazione per gestire database pgn. Al momento non ho riscontrato nessun problema e effettivamente opera secondo le caratteristiche dichiarate.

Unica nell'Appstore

Veramente un'ottima app per lo studio degli scacchi, completa di tutto e aggiornamenti costanti. Complimenti agli sviluppatori!

fedepro842016-12-22

★★★★★

Complete PGN support

This app is definitely a must for chess players. The full pgn support is not found in any other. After a tournament, I analyze my games on the phone and the quality is such that I can copy the game on my desktop with no further annoying fix. Strongly recommended!

★★★★★

App fantastica!!

Da malato degli scacchi quale sono trovo questa applicazione stupenda, offre la possibilità di studiare un database sconfinato di partite comodamente ordinate in base all'apertura ECO, e permette di importare e analizzare i propri match in modo intuitivo e veloce..per studiare e migliorare il proprio gioco non serve altro, bravissimi!

Chess Studio

Ottimo programma, completo in ogni sua funzione, adatto per gestire qualsiasi tipo di database .pgn scacchistico. Una sola cosa non sono riuscito a fare scrivere testo prima della mossa, ma solo dopo. Comunque nel complesso Super!

Marco A.

Ottima applicazione, completa, per tutti coloro che amano gli scacchi. Come utilizzatore per tanti anni del ChessBase ho trovato quest’applicazione di facile ed intuitivo utilizzo. Gestione di database, inserimento di partite, analisi di posizione sono i punti di forza uniti ad una interfaccia gradevole e molto ben organizzata. Un plauso in particolare all’autore che non manca mai all’aggiornamento continuo dell’applicazione e sempre disponibile a consigli e suggerimenti. Complimenti ancora alla competenza e al grande lavoro.

Unica!

Non è solo la migliore, è proprio l'unica app che permette di gestire completamente archivi di partite con varianti e commenti! Qualche baco e crash di troppo, risolvibili peró. Prezzo ridicolo, grande utilità. Unica pecca: l'icona è orribile, non si può cambiare? :-) 5 stelle meritatissime!

Gandalf19642015-04-19

★★★★★

Il migliore gestore di database

Se c'è qualcosa di paragonabile al Chessbase per PC, è questa app! Intuitiva, completa, consente di salvare partite, aggiungere commenti e varianti, scaricare interi tornei dal web. Qualche errore "di gioventù", ma migliora ad ogni aggiornamento su iOs. Per chi fa tornei, un must have!

dr792015-01-03

★★★★★

Ostile

L'interfaccia è quanto di più sadico si potesse immaginare. Ogni minima operazione costringe l'utente a rompersi i marroni per cercare di interpretare il pensiero dell'autore. Pagine che non si aprono, collegamenti che richiedono acrobazie di ogni genere... Le due stelle, anziché zero, stanno solo a indicare che l'idea di poter scaricare partite da internet era ottima, ma la realizzazione fa sì che l'utente a ogni passo s'interroghi: ma che ho fatto di male per meritare tutto ciò?" Un'occasione perduta. Peccato.

Pignolox1002014-09-15

★★★★★

La migliore

Sicuramente la migliore applicazione per gestire database, interfaccia ottimo e semplice da utilizzare. Stockfish per poter analizzare le proprie partite utilissimo. E poi permette di scaricare i database da Twic. Se arriveranno alcuni piccoli miglioramenti (albero delle aperture, modifica layout finestre, endgame tablebase) sarà a livello dei migliori database scacchistici da pc.
