8…gxh4It would be simpler to play the pressing R x P first. If then 9) Q - R 5, Black develops by Kt - B 3.
11…Bxc3This Knight was quite harmless, whereas the Bishop would have come in handy at K 2.
13…Nf8After the two moves it has made, the Knight is still unfavorably placed. Taking all that has been said into consideration, Black's strategy stands condemned. The tactical proof of its insufficiency is given by White in grand style.
19.Qg4Fine play. On this dangerous place the Queen takes up a most forcible position.
22.f4Wonderfully fine. The Pawn comes as a valuable ally to the heavy pieces.
24.Bxc4Elegant. If 24) .... P x B; 25) R - K sq ch and White wins the Queen in reply to any King's move; and if B - K 3, P - Q 5 would win.
27.Rh7If 27) .... R - Kt 2 White would win by 28) R x R, Q x R; 29) R x B ch.
