Negi suggests 18.Kh1!N but it seems Black can continue to push his pawns.

Does White just wait for Black to overextend?

I have no idea why @Maxwell86 was downvoted. He is correct that Blacks pawns look impressive but it is not easy to see what to do with them. The pawns are strong if they restrict Whites pieces, or if they are mobile enough to generate threats. Neither is the case here. I would regard 16..e4 as a positional blunder, because it fixes the pawn structure, and allows White to form a plan around it. This might be along the lines of Bc2-Bb3 (hold that QP), f2-f4(giving Black a protected passed pawn, but it isnt going anywhere, and White prevents Black from connecting up his Pawns with an eventual ..f4), Na3-c2-e3 (A perfect square, blockading and influencing both wings), Ra1-b1 or Qd1-d2 (protect the b-Pawn) then in due course c2-c4, Bb3-a4, b2-b4, lauching a Pawn avalanche on the Q-side.

Yes, of course Black gets to move also, but I dont see anything like this plan of campaign. White seems to me to have a big advantage because his Pawns are (or will become) mobile and Blacks will not. Whites strategy in this sort of position is always to advance on the Q-side, while Black usually looks for counterplay on the K-side, but this will not be easy with his pawns blockaded. They hardly restrict White from doing what he wishes, and they cant generate threats. It does take time for White to do everything but Blacks play is even slower. White has only one potential weakness (on g2, which the N already protects. Black will try things like Bg7-h6, Rf8-g8, Qd8-f6-g6, Ne7-g6-h4, against which White has Rf1-f2, Qd1-d2.

There is still a game ahead, but it will be the kind of game where each player forms a plan and tries to achieve their own while frustrating the oponent. My money is on White.

Black's pawns might seem impressive, but they're not so easy to mobilize. Clearly, the c3-pawn stops black's d-pawn. Due to the tension by white's pawn f3 on pawn e4, black can't push his f-pawn. And if black pushes e4-e3, the pawn ends up isolated when white plays f3-f4. Therefore, it's often useful for white to keep the tension in the center and to refrain from the exchange fxe4.

In the given main line, after 20.Qe2 Re5, according to Stockfish 9, white has the time to grab the pawn on a6: 21.Bb3 d5 22.Qxa6. White can follow up with Rad1, Nc2, Qe2, f4, after which white is a healthy pawn up and black's center is blocked.

    Mmmm, a couple of downvotes and no upvotes, apparently my answer is not good... :-D I wonder if I could get some positive feedback, in order to improve my future answers? – Maxwell86 Oct 1 '18 at 18:15
