Tambien gana} 2. Qd6 {pero en plano siglo XIX el Estudio, fundamentalmente,
ademas de mostrarla belleza clasica plamada en el, se reaslizaba tambien como
demostracion de la conclusion tactica en una posicion dada; es decir, la
tecnica de como rematar el juego en un armado de cierta complejidad, con
fuerzas disimiles... ademas, por lo general, no se competia en concursos como
los conocemos hoy con sus estrictas reglas. Es por ello que en esta nota de
caracter historico debemos tener en cuenta esta cuestion en lo que hace a lo
ancestral del estudio en ajedrez, con una mirada lindante respecto a la
practica activa del juego en si, como a la belleza, de ciertos finales,
plamada en el.}) 2... Ba6 (2... Bf1 3. Qg3 {seguido de mate.}) 3. Qc7 {
