Yafi - Internet Chess

This will never be as beautiful as little evil crows or rapacious arachnids, but at least it can challenge your brain cells.

Yafi is a chess application (called interface or client) which uses Free Internet Chess Server (aka FICS, freechess.org) as a connection point for thousands of chess players all over the world.

If you just want to play a quick game while going to school or work, or you want to meet new people online with the same passion to chess - this application is for you.

It allows you to seek games and accept games sought by other users, match them or accept their challenges, observe and examine games, chat with other users, see a list of server news items and offline messages sent to you and (obviously) play chess and many chess variants like: suicide, atomic, losers, fisher random (chess 960), upside down...

Timeseal and premove, the most important things for fast (lightning and blitz) games, are implemented.
Yafi allows you to chat with other players by using Unicode characters. Keep in mind this is not directly supported by server and not all players will see non-latin characters correctly.

You may login as a guest to play unrated games if you don't provide any credentials.

Application is supported by ads.
Version of Yafi which doesn't contain ads is now available.
You may buy it to support development.

Yafi is in early development stages, so expect frequent updates.

This application doesn't have any built-in chess engine, so you can only play online against other human beings, but also against computer players, which also connect to FICS.
It works very well on both phones and tablets.

Thanks to everybody who reports problems with the application or gives any kind of feedback and especially to Sam D., GS and LeO.
