I am still not following. Can you give the line you would play as white in which you take the bishop after Bxf2+?

I think what you are saying is that what I come away with is not equal to winning a rook. If that is what you are saying then I understand.

Right, thats what im trying to say. you do get a rook for a knight, but youre not winning the rook outright.

A game i just played where i had a disadvantage in the opening, but my opponent made an inaccuracy and i was able to equalize and eventally end up better.

maybe for move 17 Nd4 would be good and then after he makes his move you can play nb5 so you'll be up by a pawn
Yeah, but they dont have to move off the same line, so after NxR RxR and you havnt won a piece, just the exchange.
