Hi everybody, this is the game im trying to end with the LCP here in chess.com, but i got stuck. any Ideas? I was wondering about moving Nb6-a8 to prevent Rook develop. What gives?

Greetings to all! 

gosh you are stuck!!!!!!!!!!! try to plug up the b file and try to trade your knight for his bishop.  two knights don't work well together. good game! 

two knights don't work well together.

 

Huh?! Two knights are scary, tactical, forking beasts. Unlike bishops they can defend each other, and they can simultaneously attack the same square!

I don't like 1...Na8 for a few reasons. First, it loses a pawn. Second, it doesn't take advantage of the tactical nature of your knights. Third, because strategically passive defense is usually doomed and here is no exception... even after Na8 and b6, White opens some files by advancing his a- or c-pawns.

 

But, 1...Nbd5 or 1...Nfd5 are strong! Black forks White's bishop and the c-pawn. Suppose 1...Nbd5! 2.Bd6 Nxc3. Notice how Black's knight prevents White's rook from accessing the b-file, threatens Ne2+ (eliminating the bishop pair or winning a pawn), and threatens Nfd5 (giving the knights a dominating position).

 

I think if Black plays correctly, he should draw, and he might even have winning chances if White gets too cocky with his "bishop pair advantage".

Here's a recent blitz win I played out which demonstrates how well two knights can coordinate together to achieve their goals:

On an open board, bishops often dominate knights.  There are exceptions but that is the general rule.  Capablanca said that a beginner often values his knights more than his bishops in such positions because they are tricky, they fork.  As he becomes stronger his evaluation of the strength of a bishop increases.

Beginners overvalue their knights, but intermediate players often undervalue them. I think we must eventually come to respect the strengths and weaknesses of every piece. After 1...Nbd5! 2.Bd6 Nxc3 the knights are strong.

Which means, Black should definitely avoid trading off a bunch of pawns and opening the board. Then his position may become worse.

Depends on how many pawns. I find if it is 1 pawn each that are on files close together the knight can be very powerful, if it is 2 pawns at each one at each side of the board then the bishop has the advantage.  If it is 6 pawns each then the knight should have an edge.

One ability I've come to love about when protecting or stopping advancing pawns is the fact in one move the knight can protect or attack the next square infront.  The bishops can only protect attack every other square.

Like in your diagram Mr Forest take away one knight leaving the h5 knight which protect the pawn at g3 in one move to f4 he know protects at g2 and switching back to the h3 then protects the promotion square.
