For a 4 note major chord in the B system the two middle fingers are toward the edge of the keyboard, and two outer fingers are toward the baffle.
If you choose to play them that way.
For a major chord in root position it is usually a lot more comfortable to play the middle fingers two rows back, rather than one row forward. The Russians will even sometimes play D-F#-A-D using 1234 on the 1st, 3rd, 3rd, 4th rows, rather than 1st, 3rd, 3rd, 1st.
In first or second inversion, often easier to use the front row for the root.
