> Looks like a solution. Only one question is still opened... How to align letters and numbers in center if chess board should be resizable? I.e. I can't use x and y properties for that. I need anchor.horizontalCenter which use AnchorLine, not pixels…

With my solution you cannot use anchor.horizontalCenter because you are inside a Row.
What you need to do is to set the width of the Text element and use horizontalAlignment.
I suppose that in same way you are calculating the dimension of the cell during resize, so the code will be like for the Text:

Text {
    width: cellWidth
    horizontalAlignment: Text.AlignLeft
}
