Usually this side with the 2 minor pieces has the advantage. They have 2 fighting units versus the single rook. And in the above example, the side with the minor pieces now has a large lead in development.
Trading a Bishop and a Knight for a Pawn and a Rook in a Castle

That kind of exchange is very seldom a good idea for the side giving up the minor pieces. One may well say it's always bad; I can't think of a situation where that would be good.

I think white here should play with aggressive system and keep his peices behind his pawns like this :
white should avoid any trade chances

I actually played this move last week with OTB at my local club and of course lost. Won't play that again.
Actually, there is a game by Mikhail Tal where he made exactly such a trade and won a brilliancy. But what made the game famous is the fact that this trade is almost always wrong!
Have you got a link to that one.

Very interesting game. Makes one reconsider the supposed disadvantage of a rook against two minor pieces.

In my opinion,black gains no significant advantage in this early exchange by white.
Tactically this kind of play could be used for psychologically manipulation. And,strategically could serve as an early preparation for endgame.
Technically,the kings gambit puts white at a disadvantage.
But, is this really so? I play it more than any other opening.

What what I see the black king is exposedso black will lose a tempo regardless black is ahead in develpment and if he can but a rook on f8 giving him a string attack on whites kingside witch lacks a knight to defend it...

I said no "significant" advantage!
I have played this game against myself three times now and won as white.
Force blacks bishop to withdraw with Be3 and develop some pawns to limit the mobility of blacks knights. Black will eventually use a turn to reposition his king.

Generally it is a bad idea because in the middle game the minor pieces are stronger than the rook. In a pure endgame, the rook and pawn would usually be better, but it is most often a poor exchange for the side giving up the minor pieces, as their piece activity is very limited in the middlegame when there are many pawns on the board, and the rooks have little scope, and being effectively down 2 fighting units to one defensive unit in a middlegame favors the defender.

i played a game in this situation as black and i had an easy win because i was had a big lead in deveopment allowing me to go up 2pawns after a good queenside attack
using my bishop pair i was able to push a pawn to the 2nd rank forcing him to sac a rook giving me a end game with a safe centralised king, being 2 bishops and a pawn up
I remember hearing somewhere that in general, a trade in this position (or similar), where the "points" are equal, is bad for the player losing the minor pieces. I've played several games with my friends in which this is used against me, and it's unclear to me who has the advantage, though my instinct tells me that black does in the below situation. Can someone comment on/explain this?
