I'm an applied mathematician who lives in the south east of Spain.

My approach to the puzzles is similar to that of David Zechiel (User: dzechiel): I first write the variations I find in a reasonable amount of time (using the puzzle diagram only) and post them before watching the game or other's comments. Then I have a look at them and try to be critical with my work. I apply the touch-move rule to my posts (see Unzicker vs Fischer, 1960). I hope to improve my tactical vision this way.

Often I cannot even spend a couple of minutes looking at the diagram (work, family, other interests, etc.) so I try to blind solve it along several breaks. My first attempt was R Vera vs S Garcia Martinez, 2001 and although the variations I found were not very deep I felt quite satisfied with the experience.

agb2002: White has two extra pawns. White can win immediately with 22.Qxh7+ Nxh7 23.gxh7#. Much slower is 22.Qxd2. However, 22.bxa4 loses at once to 22... Qc1#. 22.Bxf6 is also disastrous: 22... Qc1+ 23.Ka2 Bxb3+ 24.Ka3 Or 24.Kxb3 Rb8+ 25.Bb5 (25.Ka2 Rxb2+ and mate next; 25.Ka3(xa4) Qa1#)

agb2002: 21.Rh1 loses to 21... Qe5, which I saw one move later but for some reason missed after 21.Rh1.
   Jul-04-15 Ulibin vs L Filip, 2007 (replies)
agb2002: Black is one pawn down. White threatens 21.Bxc7, 21.fxe7 and 21.Bxe6. The first idea that comes to mind is 20... Rxh2 21.Bh3 (21.Bxc7 Rh1#; 21.Bxh2 Qxh2+ 22.Kf1 Bxf6 and if 23.Bxe6 Bxe6 24.Rxe6 Qh1+ wins a piece at least) 21... R2xh3 22.gxh3 (22.Bxc7 Rh1#; 22.Kf1 Rh1+ 23.Ke2 Rxe1+
   Jul-03-15 Nisipeanu vs A Ivanov, 2005 (replies)
agb2002: White has the bishop pair for a bishop and a knight. Black threatens 24... Nxf3+ and 24... Nxc2. These threats and the possibility of weakening the black castle with e6 suggest 24.Rxd4 cxd4 25.e5: A) 25... dxc3 26.Qxf7+ (much better than 26.exf7+) 26... Kh7 27.Qxg6 and mate next. ...

agb2002: <thickhead: <agb2002>Even without 3.Bxd8 white wins. 1...Bxh6 2.Bxh6 Rdd8 3.Rf8+ Rxf8 4.Rxf8+ Rxf8 5.g7+ Kh7 6.gxf8=Q Kg6 7.Qg7+ Kh5 8.Qg5#> Yes, thank you. I noticed that after posting my solution.
   Jul-01-15 I Nyzhnyk vs R Pruijssers, 2011 (replies)
agb2002: White has two knights for a rook. Black threatens 29... fxg5. The white pieces are ready to attack the black king and queen starting with 29.Nxf6+: A) 29... Rxf6 30.Nd5 and White ends up a knight ahead at least. B) 29... Kf7 30.Bd5+ B.1) 30... Be6 31.Ng4+ wins the queen. B.2) ...

agb2002: Black is one knight down. The white queen x-rays the square h4. This suggests 24... Rxf1+ 25.Qxf1 Qh4#. One move longer is 24... Qh4+ 25.Kg1 Re2 26.Qf2 Bxf2#. A bit longer is 24... Qh4+ 25.Kg1 Bf4 and mate in three at most (26.R(Q)xf2 Qh2#; 26.g3 Qh2#; else 26... Bh2+ 27.Kh1 Bg3+ ...

agb2002: White has a rook for a bishop and a knight. White can win with 27.Qxh6+. However, 27.Rxf5+ gxf5 (27... Qf7 28.Qxf7#) 28.Rxf5 Qf7 29.Qxf7#.
   Jun-28-15 M Krasenkow vs Nakamura, 2007 (replies)
agb2002: Black has an extra pawn. White threatens 22.Rxb7 and 22.Bxe7. Also, the bishop on g2 aims at the rook on c6. Black can attack the white king with practically all the pieces. This and the threats suggest 21... Qxf2+ 22.Kxf2 (22.Kh1 Qxf6 wins decisive material) 22... Bc5+: A) 23.Kf1 ...

  morfishine: Hello <abg2002>! Nice write-up in the Sunday POTD! I only noticed <25...Bxe4> immediately after posting 25.Rxb4 <25...axb4>. I briefly considered deleting my post then adding this as a possible improvement but decided to leave these separate.

I'm a bit surprised there wasn't more discussion on <25...Bxe4>

Nov-14-12  Patriot: Hi <agb2002>! Good job on your win! I read your comment about losing the exchange before going over your game so when you played 20.Rae1 I figured the rook on f1 was going to be *the* piece. I've lost the exchange quite a few times like this so I'm very suspicious about moves that trap the rook.

I had a question about 11.Nxe7+. What prompted you to play this? That knight is a real thorn thanks to 9...b6?. I wouldn't recommend trading it until forced to do so since the bishop isn't going anywhere. That's similar to what Dan told me once when I captured a pinned piece. He said "You should almost never capture unless they threaten to break the pin or capture the pinning piece, for example." By not capturing, you have time to build your position further while he is left dealing with the situation.

It really looks like you did have a bad day though--we all have them! I just thought I'd mention the knight capture though because that move really stood out with me. But it's probably something you wouldn't have done on any other day!

Thanks for sharing!

Jan-18-13  Patriot: Hi <agb2002>! I loaded your game into Fritz and followed it. You played a nice game against Houdini! On move 35 (white to play), how did you evaluate the position:

click for larger view

I might think black is a little better, and Houdini agrees after 22-ply. You said 35.Bf1 was better but at 22-ply, it agrees with you! <35.Ba6>

Jan-19-13  Patriot: Hi <agb2002>! <Perhaps the note below the players showing the engine which performed the analysis misled you.> Yes this is exactly what happened--I completely misread that (sorry).

Your plan, having the outside passed pawn, is a good one. Nice game!

  Jimfromprovidence: Thanks for the constructive feedback concerning Saturday's puzzle.


Nov-01-13  Patriot: <<agb2002>: <Patriot: <agb2002> <Pattern recognition finds the mate scheme...Therefore...> If the pattern led you to the sequence, I'm impressed. I had to work out a sequence before visualizing the position as a win.> You surely have already noticed that in competition chess you never have enough 'stored' patterns.> Oh definitely! I don't doubt that you solved it this way, but it struck me oddly because I have listened to NM Dan Heisman analyze <CG> problems that I gave him, "live". And I'm quite certain he would not have worked backwards from the pattern you illustrated. And I don't think, even knowing the pattern, I would ever be able to link the pattern to the problem and solve it backwards. That's one heck of a skill!

  agb2002: <Patriot>

Thank you! The way you describe the solving process reminds me of Raymond Smullyan logic puzzles in his "The Chess Mysteries of Sherlock Holmes".

I know this is irregular, but I am stepping outside of the box, for you to view truly one of the most exciting alternate solutions ever posted on the daily puzzle:

G Weissgerber vs A Van Nuess, 1933

With friendship, respect and gratitude for your time in looking at this,


Mar-05-14  LIFE Master AJ: Hello:

Game Collection: "Chess-Games" >Problem of The Day< (2014)

I am trying to update a collection ... with all the puzzle for this year.

Have you missed any days this year ... that you know of? If so, could you help me to locate the missing days?

Mar-06-14  LIFE Master AJ: << Hello LMAJ, according to CG I have posted (or perpetrated) an analysis every day this year with the sole exception of Feb 17th (I don't remember what happened that day). If I can help you just let me know. >>

Cool! Then I will be looking through your posts and trying to update my collection. (I am glad that you don't mind.)

Think you could ask any of your friends and find out what the POTD for Feb. 17th was? (Ask them to leave a comment in my forum.)

Mar-08-14  LIFE Master AJ: S Williams vs The World, 2013

Weren't you a big-time member of the team?

Jun-21-14  Patriot: <agb2002> Thanks! I haven't been logging onto the site much recently--it's been about a week since the last time. I seem to be pulling away from chess more and more these days but that's how things go sometimes. Take care.
