FAQ (EN)

Why should I create an account?

Sync and back­up: Your reper­toire and train­ing progress are always synced between your devices. You can log into your King’s Cross account from a new or restored device and everything’s right where you left it.

Sim­pler solu­tions such as iCloud could do this as well, but I want­ed to be flex­i­ble: Although King’s Cross does not sup­port oth­er oper­at­ing sys­tems like Android, I want­ed to keep the option open and stay away from an Apple-only cloud ser­vice.

You can use King’s Cross with­out cre­at­ing an account, but it still uses an account behind the scenes — it just assigns you a ran­dom num­ber instead of an email address. You can always add an email address to such an account lat­er.

Why an email address instead of a username?

Pass­word resets: With an email address you can always request a reset if you have for­got­ten your pass­word.

Don’t wor­ry, I have no inter­est in spam­ming you. You can also enter a fake address, but if you for­get your pass­word, I won’t be able to help.

Not all moves are covered during training – why?

If some move was not cov­ered dur­ing train­ing but you expect­ed it to be part of it, check the fol­low­ing:

  • Is the train­ing depth restrict­ed?
    Let’s say the move in ques­tion (which is not part of the train­ing) is the sixth move, e.g. 6.♖e1. Make sure that the train­ing depth is not restrict­ed or that it is restrict­ed to a depth greater than or equal to 6.
    You can view and change the train­ing depth in the open­ing info by tap­ping the nav­i­ga­tion bar when the open­ing is open and then going to Train­ing > Depth. You will also see the train­ing depth in brack­ets if it is restrict­ed, e.g. Train (5).
  • Is the move exclud­ed from train­ing – either man­u­al­ly or because of its anno­ta­tion?
    Make sure the arrow of the move is yel­low. This indi­cates that the move is part of the train­ing. If the move is not yel­low, check the fol­low­ing:
    • Is the train­ing rel­e­vance set to auto­mat­ic and the move anno­tat­ed as dubi­ous or worse?
      Let’s say you are train­ing an open­ing for White and the move in ques­tion (which is not part of the train­ing) is also a move for White. Make sure that this move is not anno­tat­ed as dubi­ous (?!), mis­take (?) or blun­der (??); oth­er­wise, the move will not be includ­ed in your train­ing. (What’s the point of learn­ing a bad move?) Note that this rule only applies to your own moves, i.e. Black moves will be trained regard­less of their anno­ta­tions. This rule also only applies if the train­ing rel­e­vance of the move is set to auto­mat­ic.
      You can change the move anno­ta­tion by tap­ping the three dots in the move table and then going to Move > Anno­ta­tion Sym­bol. Make also sure the train­ing rel­e­vance is set to auto­mat­ic (Train­ing > Train­ing Rel­e­vance). You can also force the move to be part of the train­ing by set­ting its train­ing rel­e­vance to include.
    • Are there moves with bet­ter anno­ta­tions?
      Let’s say you are train­ing an open­ing for White and the move in ques­tion (which is not part of the train­ing) is also a move for White. Make sure that there are no moves with bet­ter anno­ta­tions in the same posi­tion in this open­ing. For exam­ple, if there is a bril­liant move (!!), oth­er good moves (!) are con­sid­ered incor­rect. (You only want to learn the best move for the side you’re play­ing, don’t you?) Note that this rule only applies to your own moves, i.e. all Black moves will be trained regard­less of their anno­ta­tions. This rule also only applies if the train­ing rel­e­vance of the move is set to auto­mat­ic.
      You can change the move anno­ta­tion by tap­ping the three dots in the move table and then going to Move > Anno­ta­tion Sym­bol. Make also sure the train­ing rel­e­vance is set to auto­mat­ic (Train­ing > Train­ing Rel­e­vance). You can also force the move to be part of the train­ing by set­ting its train­ing rel­e­vance to include.
  • Is there a fol­low-up move?
    Let’s say you are train­ing an open­ing for White and the move in ques­tion (which is not part of the train­ing) is a move for Black. Make sure that there is anoth­er move for White after this move, oth­er­wise the move will not be includ­ed in your train­ing. (What’s the point of show­ing a move for Black to which White has no answer?)

Why should I subscribe to King’s Cross Premium?

With King’s Cross you can man­age and train your chess open­ings. How­ev­er the fol­low­ing lim­its apply to the free ver­sion:

  • You can only cre­ate up to three open­ings
  • You will see occa­sion­al ads.

You can sub­scribe to King’s Cross Pre­mi­um to remove these lim­its and to sup­port future devel­op­ment.

What happens after my subscription expires?

After your sub­scrip­tion expires, King’s Cross will return to free mode with its out­lined lim­i­ta­tions.

If you have already cre­at­ed more than three open­ings, you will only be able to make changes to your first three ones – all oth­er open­ings will become read-only, i.e. you can­not add addi­tion­al moves to them. 

You will still be able to browse all your open­ings, train them, export them and so on.
