Is t better to have pawn couples or triplets in BB v NB OR BB vs NN or BvN or RB vs RN

Since I often trade out my rooks and strive for bishop pair, a common ending in my games is BB vs BN or BB vs NN or B v N  OR RB vs RN. What type of general pawn structure should I aim for in B vs N

That is won

Yes?

Bishops are typically stronger when there are pawns on both sides of the board. The knights have a hard time getting to different sides of the board quickly while bishops can do it easily. If the pawns are on one side of the board then it's usually fine for the knights because they don't have to go very far to be effective. RB v RN is usually better for the side with RB because they work better together. On the other hand QK is usually better than QB.

is this positon possible?

If you have the bishop pair, you should keep atleast 1 of your rooks on the board, it's not like you have extra material and you can just swap everything off and have advantage. Just a tip

That position is probably legal, due to the following considerations.

- The Black king has probably stayed on e5 for a while and received a double-check, and previously the g4 knight was on f6

- The White king has probably stayed on g5 before all the Black queens arrive on board

- Seven of Black's eight queens come from promoted pawns, while the f7 pawn has been there from the start of the game

- At least two of White's four knights come from promoted pawns, while the f2 pawn has been there from the start of the game and the f3 pawn came there as a result of exf3 or gxf3

I am lazy to construct a game leading to that position though.

I tried, but could not come up with the best idea, so I just randomly came up with moves just to reach that position.
