My idea for white would be to apply pressure on blacks isolated pawn in the centre.
I'd probably start with Rook to c2 preparing Rd2, so I can relieve the queen from it's duty of protecting the d-file.
After Rc2-d2 black can simply play ...Ne4 and after the exchange, white didn't gain anything, moreover he helped black fix his isolated weakness and improve his light squared bishop.
If white isn't ready to exchange knights after ...Ne4, then white has lost it's control over d2 square while black has got a nice outpost. Though you were aiming for a sensible thing but, your method was wrong.
I have read a few comments and came to know that there are many people who doubt the ability and level of Mr. Smirnov as a teacher.
Okay then, I have a test for you. I found this game on Igor Smirnov's website.
I believe that anyone who has studied Grandmaster's positional understanding deeply (deeply means really deep, not just watched) will have no problem finding the correct idea for white.
It's a challenge to those who think that his courses are for beginners: #46
Also to those who think that his courses are overpriced: #126
It's a special challenge to those who think that the strategic principles provided in his courses are a simple rule of thumb: #125
This game is between one of the best players of their time and anyone can find the answer by searching in any online database (and many would cheat, I know), but you not only have to tell the answer but also explain the reason of the move.
Don't think that today's top engines would let you find the correct strategic decision in this position. They are of no use here.
Those who already know the answer, whether through Smirnov's website or any other source, please do not post.
And by the way, I know the forum and most of the posts here are quite old, but, I came to know about this forum recently and for me it's new.
I like these posts! Okay, we have a classic e3+f2 g2 h2 tabiya against isolated d-pawn, the weak b5 hole is plugged by a pawn, I don't like that, pawn nicely blockaded by the knight, but threatened by the bishop, with black to play maybe Bxd5-exd5 mutual isolated d-pawns favor knights. Bishop pair vs. knight pair, I want to trade off minor pieces and pressure that d-pawn.
I'd say the position is equal, maybe slightly better for white. Knowing that 1...Bxd5 2.exd5,Ne4 is strong for black my first candidate is 1.Nce2 opening the file for the rook while reinforcing the square in front of the isolated pawn. What would black's plan be? Maybe trade off lightsquared bishops or knight for lightsquared bishop leaving me weak on the light squares? I don't see how he can viably do that anytime soon.
f5 looks like a good square for the knight, but after Qc7 it doesn't really do much. To avoid the knights becoming dangerous black will need to play ...g6 covering this vital square. A defender should defend his weakest points with the bare minimum needed and no more and make sure he keeps defensive concessions to a bare minimum as well. By itself, this weakening isn't significant enough for an advantage, but the kingside could use further work. Principle of two weaknesses: kingside and isolated d-pawn, need to work with these for optimal winning chances.
1.Nce2,Bxd4 2.Nxd4 is great for white, he likely won't exchange but it never hurts to see all checks, captures, and threats before proceeding.
If black shuffles around doing nothing then
1.Nce2,Kh8 2.Nf4,Kg8 3.Nf5 is quite strong, but black is in the game too and also looking for his best move.
1.Nce2 doesn't lose material and helps transfer it to a more active square while reinforcing the d4 point in front of the isolani so pushes clock.
