On my own and with my students I like to study the evolution of chess, not only the openings but also the progression of positional technqiues and endgame mastery. The Polish Chess Grandmaster Akiba Rubinstein is renowned for being one of the greatest endgame artists of all time. This is unquestionable, however I feel that his contribution to the middlegame and openings is often overshadowed by his legendary endgame skills. This following game is an overlooked classic that shaped the theory of the Four Knights Opening. Give it a look and you will be able to use these ideas in your games as well!
By studying the games of the great masters of the past we are better able to make sense of the modern plans and openings.
The Greeks had it right when they said,
"nanos gigantum humeris insidentes"
Dwarfs standing on the shoulders of giants
