28 Rd1 was good to keep the Black king away, and you correctly judged
that Black didn't have time to gobble your kingside pawns.

I tried a few sidelines and while some of them were okay in general it
came back to the moves you played were probably best.

Basically with passed a and c pawns going into that rook endgame there
wasn't much Black could do.

Thanks Douglas,

During the game I agreed all you wrote here.

Once the game was finished both players analized the game in the post-mortem

- We concluded that ending after 24.Kd2 seems very good for white. We
thought that maybe 25...Ke7 was an improvement (as you seems to agree
pointing that 28.Rd1 was god). But we found black had a poor ending here
too (with 25...Ke7) advancing the "a" pawn (no mater it can be lost)
and reaching a pawn ending with the king more active.

The curious fact is that Fritz after many time think 25...Ra3 to be the
best move and evaluates the ending after 24.Kd2 as equal.

- We concluded too that it seems that advancing "a" and "c" pawns seemed
the only way to put problems to black.

Curiously Fritz prefer black to eat all the possible white pawns and
white to defend them in many moments.

- We looked during tha game and in the post mortem in some moments black
can propose some pawn ending (or white needed to avoid).

Fritz seemed not worried about some of those pawn endings.

---

In conclusion Fritz evaluated some moves as "??" or "?" and I was
interested in reading here some suggestions/improvements to check if it
was correct in some of them.

thanks again,
Antonio T.

Some questions to help the analysis

- In the opening, ... what move is better 17.Rd1 or 17.Bxf8? ... ok, a
question maybe impossible to answer.

- What happens after 18...h6? (some tactics here)

- It's better Fritz suggestion 22.Ke2?

- How do you evaluate the ending after 24.Kd2? (Fritz evaluates as equal)

- It's better 25....Ke7?

- It's better Fritz suggestion 28.Kb3?

- It's better 30.a5 or 30.Re2?

- It's better Fritz suggestion 30....Rxf2?

- It's better Fritz suggestion 31.Kb4?

- It's better Fritz suggestion 31....Rh2?

- It's better 33....Rd8?

- It's better Fritz suggestion 34.Ka5?

- It's better 34....Rb2?

- It's better 41....Rd8?
