Dude i could write you a million reasons why your reasoning is absurd. Give me 2 knights, 6 pawns a rook and a queen and i will win your 6p, 2B, 1Q, 1R easy, just because you wont understand what to do:) Even your material is slighty stronger...
If you want one of the million reasons - knights can go back, pawns cant. And knight value is from 3 to 2.6 depending on a master who analizes. Theres a lot of books about it... Also for my knights ppl sacrifice rooks...:)
Um... that's NOT what I meant. Knight can go backwards, sure, but the fact that pawns can eventually turn into queens compensates for their weakness.
By the way, you wouldn't take a heavily defended knight with a rook, nor would you take a heavily defended pawn, because they rarely pose a threat to me should my opponent possess one.
However, you sometimes need to sacrifice your rook for a heavily protected bishop, because it might be a big tactical or positional threat, or assisting in a checkmate. That, I can comprehend.
mayebe youre a bad "rider" .... ah, ah, know what i mean???:D
