Rh takes advantage of the open file. Steinitz in his notes to this game, indicates Kt. Kt5 as the correct move, for then the Knight can protect the Queen's Pawn.

Black, instead of taking the adverse Queen with his Rook, moves his Knight to B3, which is a very skilful move as the King's and Queen's files are both open and if he can succeed in posting his Rooks on the Qsq. and the Ksq. he will practically have control of the board. As one Rook already occupies the Qsq. he has only to move the KR to Qsq. in his next move to give check with it. He can also give check by moving his QR to Ksq., and as White cannot move his King into any square that is not commanded by an adverse force, and as he cannot capture the attacking force, he will have to interpose, but the only men he could interpose could be captured by Black, so in his eleventh move he has to guard against this check before it is given.
