Playing strange chords

[kghayesh]

When there is a chord to be played that contains two adjacent notes (F and G for example).. Should I play each note with a separate finger or i can just play both with one finger to prevent awkward hand positions....

Examples of these chords are the chords at the begining of bars 3 and 5 in the Revolutionary Etude and the second RH chord in bar 2 in the second page of Chopin's first Ballade..

You're always welcome to play adjacent notes with just one finger.  Usually we do it with the thumb.  In the Bartok Sonata, there are some chords in the r.h. where you have to play THREE notes with the thumb--CDE, with some other stuff up top. 

The exception is if you want to voice one of those particular notes--you obviously can't voice on of the notes if you're only using one finger.  But mostly, I'd say go for it.
