Hi.
Now, the first game against Stockfish, taking the g7 pawn.
A draw.
After I played 7. gf6, I realized that Stockfish is not forced to immediately recapture the pawn, and could play 7... h5 (instead of 7... Kf6, the actual game move). I got a scare, since h5 looks like a better move. In this case, I think the position is won anyway; but a similar oversight in a slightly different position can easily cost a half-point.
After that, 11. f5 is just a bad move from me. It leads to an easy and immediate draw.
I should have played d3, c3 (d4, if allowed), and kept maneuvering with my king... I think Stockfish would have ran out of waiting moves. But it is easy to see all that in hindsight; during the game it is not obvious.

Re: Pawn endinge challenge: human vs engines.
Hi.
Now, the game against Berserk, taking the h7 pawn.
A win for me.
In this occasion, Berserk did not really offer much resistance.
I even ended up with more than nine minutes on the clock (in several other games in this challenge, I have ran low on time).
I had to be careful, but still the game was pretty straightforward.

Re: Pawn endinge challenge: human vs engines.
Hi.
Now, the game against Crafty, taking the a7 pawn.
A win for me.
I had my doubts about playing 13. a6 (I also considered 13. ab6 and 13. e3). But I did not see a way for Crafty to keep the kingside closed, so I went for it.
I still do not find a way to prevent Crafty from resigning. Of course, the final position is an easy win for me; but I still had to be careful to avoid a stalemate.

Re: Pawn endinge challenge: human vs engines.
Hi.
Now, the first game against Komodo, taking the b7 pawn.
A draw.
I think I just played badly.
12. c5 is a poor move that leads to an easy draw. I missed that my a5 pawn needs eternal protection, so my king is not free to go to the kingside.
But even I had played something else (cd5, Kd3 or f3), I do not see a clear way to make progress. So, my poor moves began before that.

The next game is against Lc0, taking the c7 pawn.
Greetings.
Now, the first game against Komodo, taking the b7 pawn.
A draw.
I think I just played badly.
12. c5 is a poor move that leads to an easy draw. I missed that my a5 pawn needs eternal protection, so my king is not free to go to the kingside.
But even I had played something else (cd5, Kd3 or f3), I do not see a clear way to make progress. So, my poor moves began before that.

Hi.
Now, the game against Lc0, taking the c7 pawn.
A win for me.
As usual, I had to play carefully. But the game itself was not very difficult.
I liked my maneuver g3 and h4, to keep the kingside open for my King.

Hi.
Now, the game against Stockfish, taking the d7 pawn.
A win for me.
At first, Stockfish did not advance its pawns too much, which is an interesting defensive setup.
One has to be very careful to avoid closing up the game.
In the last few moves, I had to avoid stalemating Stockfish.

Hi.
Now, the first game against Berserk, taking the e7 pawn.
A draw.
I think Berserk defended extremely well, and I am not completely sure where I spoiled the win.
According to Berserk's evaluation, 22. d5 is a mistake, and it is a draw after that.
Of course I did not see it during the game, but it is now clear to me that the position after 22. d5 is indeed a draw.
But, truth to be told, I have no idea about the winning plan there. I could play 22. Kd3; but, ¿how to follow up?

Hi.
Now, the game against Crafty, taking the f7 pawn.
A win for me.
I still do not find the way to keep Crafty from resigning.
An straightforward game, which looks "easy" once it is played out.
But during the game, I had to be careful, as usual.

Re: Pawn endinge challenge: human vs engines.
Hi.
Now, the first game against Komodo, taking the g7 pawn.
A draw.
I am not sure where I let the win slip away.
But I am quite sure that Komodo's evaluation after 18... a4 (it gives +2.38) is just wrong: the game looks dead drawn to me.
Had I played 19. a3 (instead of 19. Kg4), I just do not see any essential difference, there is no way for me to make progress.

Re: Pawn endinge challenge: human vs engines.
Hi.
Now, the game against Lc0, taking the h7 pawn.
A win for me.
A got a big scare in this one. After 15... a5, my original intention was to play 16. de4 de4 17. a3, but then I saw that Black is not forced to capture on a3, and the queenside gets closed for my king. If I wait for Black to play ... a4, I think the position closes too.
Fortunately, I saw 16. de4 de4 17. c3, which wins. I think I waited too long to expand on the queenside. And had I waited any longer, I would have lost half point.

Next game is against Stockfish, taking the a7 pawn.
Greetings.
Now, the game against Lc0, taking the h7 pawn.
A win for me.
A got a big scare in this one. After 15... a5, my original intention was to play 16. de4 de4 17. a3, but then I saw that Black is not forced to capture on a3, and the queenside gets closed for my king. If I wait for Black to play ... a4, I think the position closes too.
Fortunately, I saw 16. de4 de4 17. c3, which wins. I think I waited too long to expand on the queenside. And had I waited any longer, I would have lost half point.
