(11) White's Queen now takes advantage of the open file and captures the Queen's Rook, at the same time giving check.
As White has given check, Black must avoid it and there are two things for him to do; move the King or take the attacking force. The latter, of course, is the better play, as the Queen, if left on the board, could again give check.
At this point in the game, the student should study the positions of the White men and of the Black, and he will see that it is quality of position rather than quantity of men that gives Black the advantage. Black has lost a number of his men but the others are so well developed that they have far more strength than White's which are either pinned in or undeveloped. White's two Rooks and his King's Bishop are shut in by their Pawns and his King's Knight is pinned to protect the King from the adverse Bishop.
