Black to play.

Here's a good endgame to work on during spare time.
|Jul-02-13|| ||YouRang: <David2009><I am retired, living in rural France.>|
That sounds like the good life. :-)
|Jul-21-13|| ||LIFE Master AJ: <<Thanks for posting your problem to my forum: it attracted irrelevant comments like a jam-jar does wasps.>>|
No hard feelings ... and I appreciate the kind comments. I hope you have a good summer! (See you - back, and full force - in the fall.)
|Jul-22-13|| ||The Last Straw: Let's try to assess 1...exf4+.
I already know from a book that the position after 2.f3 is a draw, but can you find anything better? (No, I'm not sure if there is).
Hope to see you around more in the autumn!
|Nov-30-13|| ||LIFE Master AJ: Hello. Stopped by to say hi and wish you a safe and cheerful holidays.|
|Dec-28-13|| ||morfishine: <David2009> You are very kind sir! I've done a poor job of keeping in touch with friends this fall. I hope you have a great New Year!|
Tell me more about your exploration of Coursera
|Dec-31-13|| ||David2009: <<Morf>:[snip] Tell me more about your exploration of Coursera>. Not much to say. I have taken four courses getting certificates for three. All were good but perhaps the most interesting and challenging was the Introductory Physics I with Laboratory course run by Professor Michael Schatz and his team from Georgia Tech. Basically the course is about simple mechanics starting with Newton's three laws of motion and the momentum principle. The twist is the classroom exercises: you have to film moving objects with your mobile home or video camera; then analyse the motion frame-by-frame using public-domain software; then compare experiment and theory using a computer program called Python to do the math for you (i.e. doing calculus by arithmetic rather than algebra); and finally report the whole thing by posting a five minute video onto You Tube. It is this last step that I found very difficult. The physics has hardly changed since I was at school 50-55 years ago, but reporting by video (rather than posting a document) really took me out of my comfort zone. When I started I had great trouble getting the blessed software to work for posting text to You Tube in readable form, and could only manage to sort out a commentary in my final effort. This can be seen at “How to fall off a ledge” at http://www.youtube.com/watch?v=nAxh....|
Happy New Year to one and all!
|Jan-01-14|| ||morfishine: <David2009> Congratulations on your video! I think it was better than you suggest: Keep in mind, that live presentations, of any type, can always be improved upon since there are so many areas to scrutinize. If I were to offer any advice, it would be related to short presentations (5-minutes is very short, especially for this subject matter): Get right to the point since there is such little time to work with|
Now you've re-kindled my interest in Coursera. Coincidentally, Physics was a big problem for me in college: I did well in Calculus and Chemistry, but since I couldn't get past the Physics courses, I had to switch from Engineering to Business; maybe, I can finally get that monkey off my back!
Thanks, and congratulations again on your first U-video, well done!
|Jan-01-14|| ||LIFE Master AJ: That was quite a compliment you left on my player page ... |
Thanks! Happy New Year!!!
BTW, thanks to the actions initiated by <TheFocus> I now enjoy peace, (on this site). It was an absolutely amazing turn of events and it could not have been predicted by anyone. Even <Colonel Mortimer> and I have smoked the peace pipe and have abandoned our strife.
I cannot tell you how much this pleases me! Praise God!
|Jan-02-14|| ||David2009: <AJ>, <Morf>: Thanks very much for these kind words which have helped get my New Year off to a really good start! Cheers, David|

Are you a teacher? Physics major?
Trust me, I am not trying to be ugly, I am just intensely curious. (About a great many things!)
I know that my critics paint me as an ignoramus who knows nothing and only has some knowledge about chess, but this is actually incorrect ... I am curious about many different subjects, to include the natural sciences.
BTW, a lot of Christians are generally represented as being non-believers of science or saying that all of science is incorrect. I am firmly in the field that most science is both logical and correct. The stereotype is unfair but the one that Hollywood always seems to resort to. In fact, most movies (that I know of) always present a Christian as a nutjob/psycho ...
I also believe there is a lot of <supposed> science that is only a theory and borders on religion and is completely unproven. (Two good examples, for me ... anyway, are global warming and evolution.)
|Jan-05-14|| ||LIFE Master AJ: BTW ... a little known fact was that (when I was very young) I really wanted to be a paleontologist. (I have been absolutely insanely crazy about dinosaurs for as long as I can remember. The movie, "Jurassic Park," - I also read the book as well - bordered on being a religious experience for me, hehe. I have been told, when I was <about> 3-4 years old, I had a little plastic, yellow toy dinosaur ... and I carried it everywhere I went for several years.) |
Unfortunately, when my maternal Grandmother told me that this was not a good profession to be in, I basically believed her and allowed her to (permanently) sway my opinion ... all I can say (in my defence) is that I was very young.
|Jan-18-14|| ||morfishine: <David2009> Thank you very much for the information! Let me know when you post new videos!|
|Jan-25-14|| ||David2009: Crafty End Game Trainer has received a new lease of life. It is now programmed to try alternative lines which makes it much more challenging to play against. I have tried by luck with the ending Q vs R in a position which is a tablebase mae in 27. |

Crafty EGT link: http://www.chessvideos.tv/endgame-t...
Without tablebase help, finding the win is very challenging and I have frequently only drawn (i.e. winning in over 50 moves). I stop as soon as I capture the Rook. The fastest win starts Qe6+. If you get stuck, try the Nalimov table base http://www.lokasoft.nl/tbweb.aspx. This last uses Java and you will have to give your computer the appropriate parmission as described by Chessgames.com in their link Java Help Page.
You may also like to explore defending the ending, for example using the following link:
or alternatively a link to the diagram position colours reversed
so Black can mate in 26 with best play
Crafty normally finds the win efficiently: your task is to postpone losing as long as you can. Excellent training!
|Feb-20-14|| ||morfishine: <David2009> Hi David! Yes, I have tried 10-min and the quality improved instantly and dramatically. The reference I made to 5-min chess over in <Patriot>'s forum relates to a training exercise I undertook in 2012 and half of 2013. I played about 1,300 games of 5-min chess with the idea of speeding up calculating speed and enhancing time mgmt skills. Hopefully this would carry over to normal OTB controls. Some GM's advocate speed chess for these type of reasons. |
I did well pushing my 5-min rating up to 1870; but as soon as I stopped doing tactics every day, and I stopped playing so much 5-min, my rating dropped like an anchor: it was that fast. Oh well, I know what it takes and how much discipline it takes to play good 5-min chess. I just don't have the time or desire to maintain peak efficiency at that time control.
Thanks for the comments! I still take my scalps, just not in heaps like before :)
|Mar-10-14|| ||David2009: I previouslyt edited my User profile on 13 November 2009. The information below was current on that day:|
I am retired, living in rural France. I used to play club chess in England until fifteen years ago. I have a temporary rating of about 1700 standard, 1400 blitz from the Free Internet Chess Server (FICS) at http://www.freechess.org/ . I am registered as DavidMMIX. I prefer standard games 5/15 (meaning 5 minutes initially plus 15 seconds per move). Please email me at DavidMMIX@gmail.com if you would like a game and we can agree a convenient time. France is 1 hour earlier than UK time and 4 hours later than US Eastern Standard Time .
When I joined Chessgames.com my first act was to look up games with the NN vs P ending, which has interested me for a long time. I have moved material on the NN v P ending to David2009 chessforum I have now widened my interests to endings in general.
I have become a daily puzzle addict. Following the example of <dzechiel> and others, I like to write out my solution (in Notepad) and then post it, warts and all (apart from proofreading), with a brief comment after I have seen how the game went. These "brief comments" have recently become longer, because I have discovered a free on-line version of the Crafty chess computer on the www.chessvideos.tv site which enables me to check my analysis and also win (if I can) the theoretically won positions. Thanks, Chessvideos! You can compose your own problem or have a go at a standard ending. Link: http://www.chessvideos.tv/endgame-t....

|Mar-30-14|| ||LIFE Master AJ: Thank you for your fime comment the other day, it was much appreciated.|
|Apr-01-14|| ||LIFE Master AJ: DeFirmian vs N Ristic, 1981|
I got a few comments and a few e-mails about last week, I annotated three games, Monday-Wednesday.
Above is yesterday's contest, I am interested in what you think about it.
|Jul-12-14|| ||David2009: Is the Traxler counter-attack unsound? I never normally allow it: as Black I am afraid that White will cash the forced draw, as White if I avoid the forced draw I am worse off. HOWEVER this assessment may be arong.|
I am having a fascinating on-going turn-based (correspondence) game on www.chess.com with Jonathan Birchley (aka User: scormus. The game started 1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 Bc5 5. Nxf7 Bxf2+ 6. Kf1 Qe7 7. Nxh8 d5 8. exd5 Nd4 and we reach

The immediate 9.Kxf2 loses quickly to Ne4+ followed by Qc5. But Jonathan finds an improvement: 9.d6! cxd6 10.Kxf2. Theoretical novelty (TN)!

Black is R and B behind - now what?
After long cogitation I went for 10...Bg4. I think other lines lose for Black.
NO comments with specific variations YET, please. But watch this space!
On chess.com my handle is DavidMMIX. See you there!
|Jul-12-14|| ||scormus: It will be fascinating to do analysis and discussion later. I'll just comment that I cannot take any credit (or blame) for 9.d6. It was suggested to me a year or so ago by someone else. Whether it's ! or ?, it certainly requires strong nerves to play the ensuing position!|
|Jul-12-14|| ||morfishine: Hello <David2009>! Great to hear from you! Glad you enjoyed my comments on Napoleon. I enjoy wargames, especially from the Napoleonic era and the US Civil War. The strategy and tactics involved are to me at least, quite interesting.|
As far as I know, Morphy's "method" was based on quick development. One thing about Morphy is though he was a marvelous attacking player, he was a precise and stubborn defender too. I don't think Morphy has been credited enough on how astute he was at defending. Of course, he rarely was on the defense, but when he was, his accuracy was uncanny
Interesting game vs Scormus: Why not 9...Qxd6 maintaining the threat ?
|Jul-13-14|| ||morfishine: <David2009> If you are interested in Napoleon's campaigns, I'd suggest reading
up on Jena, Austerlitz and Waterloo.
Waterloo is a particularly striking example of "moving in 3's" where a smaller
army attempts to defeat a larger force in detail. With the British grouped around
Brussels and the Prussians around Namur, Napoleon drove northward directly
over the sector where the Alllied lines overlapped. One column drove up the
Brussels road, another column pushed NE towards Liege while the third column
trailed behind ready to reinforce either wing depending on circumstances.
Napoleon was presented with a gift at the outset when Prussian General Blucher
rashly moved south, thus lengthening the distance between his army and
Wellington's army. Even worse, his movement was premature in that only 3 of his 4 corps were at hand; furthermore, the missing IV corps was his strongest. Much wiser would have been for Blucher to shift westward effecting a union with
the British army before Napoleon could initiate an engagement.
Here, fate stepped in to poison Napoleon's plans: His reserve column failed to
reinforce either wing, marching to and fro due to a communications gaffe. Thus
the British were barely able to hold onto Quatre Bras while the Prussians
desperately held onto Ligny before retiring after being roughly handled. In essence, the allies fought two delaying actions and were fortunate neither
Napoleon's bad luck continued when weather (rain) hindered his pursuit of the
British northward towards Brussels. Napoleon then worsened his position by
detaching 1/4 of his force to pursue and "delay" the Prussians or prevent them
from joining the British. This fatal miscalculation is hard to understand since
Blucher had a full day's head start and could simply march north then west joining the British. This is exactly what happened.
Still, despite all this, Napoleon came within a whisker of defeating the British
before the Prussians arrived. In hindsight, Wellington would have been soundly
defeated if Napoleon had Grouch's force at hand. But such are the fate's of
|Jul-15-14|| ||scormus: I had in mind to comment on the game and now is the time.|
Here is the game which took just 17 moves for me to lose, though a lot happened in those few moves
1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 Bc5 5. Nxf7 Bxf2+ 6. Kf1 (generally considered better than Kxf2?! which seems to give the advantage to B after 6 ... Qh5+ and several forced moves to follow)
6 ... Qe7 7. Nxh8 d5 8. exd5 Nd4
we have reached a key position in the Traxler. The classical continuation that dates back to Traxler himself starts with the eminently reasonable 9. c3?! and continues ... Bg4! 10 Qh4+.
A well known line thanks to an entry in an old edition of MCO is 10 ... Bd2?? 11 Qd1?? Bg4 12 Qa4+ 1/2 - 1/2. In fact both W and B "miss" 11 Qa3!, winning. One reason for playing 9.c3 at club level is B might go for this line!
In fact B must play the odd looking 10 ... Nd2! After 11 Kxf2 B can easily draw by 11 ... Qh4+ followed by an easily found forcing line which ends with repeated checks on WK by with Q and N. Can B do better? If so its damn hard to find. Perhaps David, you'll play it with W against me to find out ;)
Our game continued
which I am convinced leads to a win for W. I take no credit here, a couple of years ago I had some correspondence with the delightful WGM Natalia Pogonina who assured me it wins and c3 only draws at best. When I did an engine analysis I satisfied myself that d6 is indeed winning, but W has to play very carefully, quite possibly having K on f2 and B N's on d4 and e4 to deal with.
9 ... cxd6 (I am not sure which is better cxd6 or Qxd6)
10. Kxf2 Bg4! (tempting as ... Ne4+ is, I think Bg4 is actually the best move, well chosen David)
11. Qf1 O-O-O 12. c3? (according to Rybka, 12. Qg1 is better)
Ne4? (according to Rybka, Nxc2! is much better but not enough to get equality)
13. Kg1 Rf8 14. Qe1 (Rybka prefers Nf7 with big advantage, but Qe1 is still winning)
14 ... d5 (again Rybka prefers Nc2)
15. cxd4 dxc4 16. Qxe4 Qh4! (the best chance for B, though with correct play this position is overwhelmingly winning for W)
17. g3?? defends against on mate threat but not both
17. Qe3 seems to parry both mating threats but loses in a few moves anyway. The only move if 17. Nf7!!, diverting the BR away from the back rank where it's needed most. What I mean about having to play carefully.
|Jul-16-14|| ||morfishine: <David2009> Yes, that is a very interesting perspective identifying the different struggles at Mount Saint Jean vs the British on June 18, and the follow up offensive by the Prussians afterwards. Its easy to gloss over the fact the Prussians were pressuring Napoleon's right-rear at Plancenoit fairly early in the afternoon, between 4-5pm. |
Ironically, Grouchy gave a very creditable performance covering the rear of the retreating French army between June 18 - 22 as it withdrew towards Paris.
|Jul-17-14|| ||morfishine: <David2009> Thanks for the problem! Nice write-up by <scormus> |
<17.Nf7> is the only move
