Book erratum or lack of sight?

Hey guys, I´m currently studying the "General Chess Treatise" by Roberto Grau, and I'm solving some exercises in which I need to count the available moves for the pieces. In this particular one, the book solution says whites have 31 available moves, but over and over I keep counting 37. I really need another set of eyes to tell me if I'm overlooking something or if it's a book erratum and to expect more of these (It's an old edition). Thank you for you assistance. happy

It is correct, There are 31 moves.

The knight at e7 has 6 moves, but 1 is illegal because another knight occupies that square, So 5.

The knight at f5 has 8 moves, but two squares are occupied by a Rook and another Knight, So 6.

The rook at e1 has 6 moves, The rest of the moves are blocked by the King and the other rook.

The rook at e3 is pinned by the Black queen to the king, so 0.

The pawns on the left have 5 moves, The knight blocks the 6th move.

The pawns on the left have 4 moves.

The f pawn can't move because the knight occupies that square, so, 0.

The king has 3 moves, The other moves are occupied by pawns.

5+6+6+0+5+4+0+3 = 29 (?????)

Either the book is wrong, or my brain is.

Nf5 has 6 no??

Queen? WHERE IS THE QUEEN?

Is it the slightly black one? WHY IS IT SO BLACK COLORED????

White queen is the one on h6. The printing is very small and it's missing detail. Black does not have 2 queens because my black moves count matches the book solution (40).

The white queen is on h6. I found a preview on Google Books of a newer version where this can be seen clearly (diagram 60 on page 51). But the solution isn't in the preview.

I also count 40 moves for black.

Do you have a picture of the solution? Could the 7 look like a 1?

This is what I think too. Either a misprint or a blurred number.

It is a misprint. In my edition it's diagram 61 and its clearly a 31 in the solution. I also counted diagram 62 and solution says white has 37 moves as well, which is correct. So... definitely a misprint for diagram 61. I believe there will be more, these old books always have them.
