  TheFocus: Sir, do you remember what the openings were in your two blitz games in the Manhattan Blitz Tournament in 1971 against Robert Fischer?

Seems like those game-scores were lost to time.

Jun-16-13  bavaria: hi neil, have you ever seen/met sonja graf-stevenson. the us women's champ of 1964? thanks in advance by bavaria
Jan-03-14  morfishine: <ChemMac> I want to say I enjoy your postings. We haven't been introduced, so I hope this is not an intrusion. I hope what you stated over at the WT game takes hold (with regards to various postings and ratings). A slim chance, but perhaps some will follow the example. I would like to drop a line from time to time
Jan-22-14  Ceri: Hi, ChemMac,

My son started at Oxford last September, reading Biochemistry.

I taught him chess, but he won't play with me. His group self-taught themselves Bridge at school and they tell me that he was the best of them, but he won't play with me. All too "un-cool" for him.

Nevertheless, he is a Grade 8 viola player and his recent Collections show him on trend to a first, so it's probably best that he didn't get as diverted by games and sport as I was! I was into almost everything: Rugby, Cricket, Soccer, Tennis, Athletics, as well as Chess and Bridge. I only made grade 7 on the piano.

I was once a chemist but have been on the marketing end of the oil business for 40+ years.

I enjoy your contributions to the debate - long may they continue.

  ChemMac: <ceri> Thanks - I haven't been checking my own page. Two of my undergraduate chemistry students won Rhodes Scholarships, which unfortunately send one to Oxford rather than Cambridge!

I have walking difficulties (knees; back: the left knee had a soccer injury when I was 16 - never properly treated - and that came back to haunt me 50 years later). Even so, I hope once again to take my usual August UK trip with my lady friend who is an opera conductor and voice teacher.

Chessgames has just four games by me. The two vs. Steinmeyer were when I had just started serious playing again on joining CCNY. The one which I won was interesting, although I should have played Ba8 at once when I had the chance. I sent in a few which were ignored....

For years there were five frequent Manhattan Chess Club competitors, all with USCF or FIDE ratings 2350-2430 or so. These were Arnold Denker, Walter Shipman, George Kramer, Arthur Feuerstein, and me. Chessgames has many games by the first four. Each of us managed to win the title occasionally, but usually Benko or Bisguier and later Benjamin would come first.

Since you asked, here are four wins by me, naturally with the White pieces.

Neil McKelvie Arnold Denker (this one deserves notes...) 1.e4 c5 2.Nf3 e6 3. d4 cd 4.NXd4 a6 5. Nc3 Qc7 6. Bd3 Nc6 7. Be3 Nf6 8. Qe2(?) Bd6 9. g3??! This is a truly awful move but played deliberately! Denker, as I knew from long experience, was prone to overconfidence, and this made him smile happily! (A real Patzer move!!) Whites white-square weakness will be very bad. Denker plays logically, to free his Bishop from c8. 9NXd4 10.BXd4 e5 11.Be3 Bb4 12.O-O! B:c3 13 bc O-O? (13d6! of course, and White has a miserable position. One poor move deserves another!) 14, Bg5 Qc6 15. f4 ef 16. e5 f3
After Denkers f3, I should have taken on f3 with my Queen. Then QXf3 (or after Q checks, Qe3) RXf3; if then Ng4; Be7 Re8; Bd6 NXe5; Re3 f6; Bc4 Kh8; Bf7 wins the exchange, right? Other lines; White seems to have a winning game, with two Bs and a B position suffering from acute constipation. 17 RXf3 Ng4 Thinking that the White e-pawn will be lost.. 18.Be7 Re8 19.Bd6
Denker intended 19N:e5 20 B:e5 d6, but then looked, and saw 21. BXh7+ IF 21KXh7 22, Qd3+ Kg8? 23. BXg7! KXg7 24. RXf7+! KXf7 and White wins in all variations. This would not work without Blacks 4...a6 and 14..Qc6, because one variation is 24 Qh7+ Ke6 25.Re1+ Kd5 26. Qd3+ Kc5 27. Qd4+ Kb5 28. Qb4++ However; Black should play 22.f5. 23. RXf5 can lead to a draw by perpetual check, but no more. I planned 23. Bd4. Denker thought this was bad for him, at least cosmetically, but his W. Bishop is equally frightening. Maybe both sides are losing! I havent had the nerve to give this position to a computer.

Denker played, after L O N G thought, 19b5? (Why do so many long thinks lead to chessic mental paralysis and a blunder?) 20.Qe4! QXe4 21.BXe4 Ra7 22.Bd5 Nh6 23.Raf1 Re6 (threat was 24 R:f7!) 24.BXe6 de 25.c4 bc 26.Rc3 Bd7 27.Rb1 f5 28.Bb8 Ra8 29.RXc4 Nf7 30.Rb7 Nd8 31.RXd7 RXb8 32.Rcc7 Resigns

Jan-22-14  Ceri: Dear ChemMac,

Given my games history, you will hardly be amazed that my knees are not fantastic, either.

I tore the cartilage in my right knee in a tennis tournament in 1997. A couple of years back I had some cleaning out work done and learned that I have no cruciate ligament that side. I injured it twice: rugby first and soccer in 1973. I played rugby until 1988 blissfully unaware that I was 1 ligament down, although the knee was prone to swelling.

Keep well for August - I will be in the Algarve for most of that month.

  ChemMac: <ceri> Mara expects to be teaching a summer course for young singers on operatic performance in August; sold out last year, so they want her to give it again. Therefore; if I'm up to it, our trip to Europe and the UK may be end of August and early September. If you are back from the Algarve, we could meet up.
Jan-23-14  Ceri: Hi, Neil,

I guess that we know enough about each other for me to use your real name.

If we maintain our current plans (likely) then we should return on the ferry to Portsmouth on the evening of August 26th. We are currently planning another African adventure for mid-September. "Do it before my knees give out" is my mantra.

Sue and I would be delighted to meet you, if it could be arranged. She doesn't know of this plot yet, but she gets on like a house on fire with AuH2O and his family. He is a Federal Judge, based in Tampa.

We live in Pimlico, London SW1. Our cellar and cocktail cabinet contain various, diverse, lubricants.

Kind regards,

  ChemMac: <ceri> As of now, we should be in London from perhaps Aug 12; then - neither of us has ever been to Wales! We may rent a car, because getting into and out of railway carriages is very difficult for me. Then back to London; leaving for NY perhaps Friday Aug 29 - just after you return. We'll probably stay as usual in the Rembrandt in S. Kensington.
May-14-14  Ceri: Perhaps we should keep a weather eye open for getting together on 28th August.

After returning to London on 26th, Adam is travelling on 27th, so we could make sure the house is ship-shape by 28th.



Premium Chessgames Member
  ChemMac: <ceri> Unfortunately Mara has to get back to NY for opera rehearsals earlier, so we'll be in London from Aug 6 and leave the afternoon of Aug 21, with a four-day drive north from Aug12 through Aug 15. otherwise: Rembrandt hotel as usual. The new world team game just started. It looks like we shall not begin with 1,b3! Non-Chess: I did get a special "Judges' Prize" in the just concluded Chicago International Amateur Piano competition, but was not in the finals.
Jun-28-14  morfishine: <ChemMac> Nice game against Shipman
Jul-20-14  samsloan: The player you describe on Mar-30-13 is almost certainly Bernard Zuckerman. He always does that. Your son played in the World Open in about 1985 and lost all his games. Did you know about that?

  ChemMac: Anyone in London (Ceri?)

We shall be again in London between Aug.11 and Aug 26, staying again in the Rembrandt Hotel in South Kensington (except for a short trip to the Midlands with a rented car between Aug 18 and Aug 21)

Aug-16-15  SimplicityRichard: <ChemMac> Yes indeed. I'll meet you tomorrow morning or after Saturday the 22nd August after your car-trip around the UK.
Dec-19-15  Shams: Hi Neil,

I know we haven't spoken much but believe it or not I was mentally running through a list of people I know (in real life or online) who might be willing to field a chemistry question and yours was the first name that occurred to me! Would you be game? My guess is you might have a general idea and that would be a help for me.

Happy holidays either way.
