Really nice game. The user interface is cool and fun. However, the engine is far too precise. I'm definitely not a GM but I'm not bad either and it's just too hard to win.
A_M_A_Z_I_N_G game ! I think the only down side is the UX (many many clicks to get through the game). I understand thats the type of games, but nowadays, it always feels a bit tiring after a while
