Annotated chess game

I don't see why black would win. As I'd think that white would have an advantage, especially with black's doubled pawns.

I can see why as it's left on the rim.

As would I.

I would've refrained from doing so with 13.c5 instead. As I wouldn't see a good reason for exchanging pawns, but seeing that you did it proves me wrong.

And, I can see why since e6 is threatened which more or less, forces his next move. Although it looks even, from my evaluation, I'd say that you have a slight edge since I'd be more comfortable playing as white then with black.

I would've considered castling the best. But, having said that, I have to agree with them since castling appears unsafe for black, anyhow.

I disagree with them here and give this move as best.

Which is why I'd also play this.

Black has been left with a 'hanging pawn couple' in the middle of the board, both pawns on half-open files. As such, they are more than somewhat vulnerable. He probably does right to make such use of their dynamism whilst it lasts.

18.Nb5 a6 19.Nxd4! with advantage. There seems to be no good way of preventing Nxd4.

Fritz was planning 18.Nb5 a6 19.Na3 and disagrees about 19. Nxd4 leading to an advantage.

I would agree with Fritz since that blends with my way of thinking, and this is what I also would've played. But, I'm gonna have to disagree with them, as there's a reason why white would take on d4. Now, I'd recapture with 19...exd4?? but from what ION posted, I see that something bad would happen if black takes back. So, this is where to take would be a mistake.

All the alternative permits White to develop threats: [a] 19...Kd8, 20.Qe2; [b] 19...Ke8 20.Rc1; [c] 19...Kf7 20.Bc4 or Qb3; [d] 19...Kd6 20.Bf3; [e] 19...Ke6 20.Bc4. So 19...Kf8 falls into the category 'only move'.

Agreed!

Weak vs non-existent!

As do I.
