I believe White gets big advantage in the position you mentioned.
Black has weak light squares, passive bishop and backward development.
Furthermore, there is no obvious plan for creating counterplay because White will finish development first, thus he will be the first one to start attacking.
White does have doubled f-pawns, and f5
pawn is "shaky" but the hole on d5
, firm grip on the light squares, space advantage, bishop pair and development advantage more than compensate for that.
White should aim for fianchettoing White's light squared bishop, and try to quickly finish development. I also like your suggested g4
to grab more space and claim more light squares. In the end, Black should simply collapse under pressure your light square domination and development advantage create.
One sample line illustrates just how difficult it is for Black:
[FEN "rn1qkbnr/1p3ppp/p2p4/4pP2/8/2N5/PPP2PPP/R1BQKB1R b KQkq - 0 1"]
1... Nf6 2. g4 Nc6 3. Bg2 h6 4. h4 Rc8 5. g5 hxg5 6. hxg5 Rxh1+ 7. Bxh1 Nd7 8. Be3 Qa5 9. Qd5 Qxd5 10. Bxd5 Nb4 11. O-O-O Nxd5 12. Nxd5
Engine suggested ...Nc6
as the strongest reply but I decided to stick with the fianchetto idea. After analyzing for a few moves, White emerged with an advantage.
[FEN "rn1qkbnr/1p3ppp/p2p4/4pP2/8/2N5/PPP2PPP/R1BQKB1R b KQkq - 0 1"]
1... Nc6 2. g3 Nge7 3. Bg5 d5 4. Qh5 Qd7 5. f6 Nf5 6. O-O-O g6 7. Qe2 d4 (7...Nfd4 8.Rxd4 Nxd4 9. Qxe5+ Ne6 10.Nxd5) 8. g4 h6 9. gxf5 hxg5 10. fxg6 fxg6 11. Ne4 O-O-O
White has development and space advantage, which is enough to create initiative. Light square domination and bishop pair bolster this advantage to the almost decisive one.
I have used engine in order to try and find best plan for Black to finish development and confront White's light square dominance, but as can be seen, White will always enjoy stable advantage.
Therefore I agree with your assessment and I do not think you are biased toward White's position. White does have a big, stable advantage in the position you mention.
Please note that I have performed brief analysis, maybe someone can offer detailed high quality analysis that finds even stronger plan for White. I also doubt that even the best play can equalize, or even save the position for Black in the long run.
