Kibitzer's Corner
Nov-02-03  Resignation Trap: This Colombian player caused a minor sensation at the Stockholm Interzonal in 1962. He was in the lead after two rounds. This he accomplished by the simple task by defeating Geller and Korchnoi!

  Chessical: Cuellar also gave a nasty fright to a young Karpov in R.7 of the 1973 Leningrad Interzonal.
Nov-03-03  Resignation Trap: Reshevsky was also given a drubbing at the Sousse Interzonal in 1967. See:

Cuellar-Gacharna vs Reshevsky, 1967

The finish of this game was really cute.

Nov-22-06  setebos: Dangerous dude, perhaps underestimated by his esteemed Soviet colleagues.

  Albertan: One thing you can say about Miguel Cuellar Gacharna is that he was consistent. According to my Chessbase program, he scored at an elo of 2390 while playing the White pieces and an elo of 2392 when playing the Black pieces. He scored 9.5/14 at the 1972 Skopje Chess Olympiad, however he had an awful result at the 1973 Leningrad Interzonal (1.5 points in 17 rounds of play).

Position after 87 moves, black to play.

Wit heeft de pion niet genomen - begrijp jij het, begrijp ik het - en is met zijn koning gan zwerven, tot f2 toe. Hij zag echter dat de koning op de damevleugel - de doorbraakvleugel - nodig is en streeft nu naar veld a3. Het is vlak voor de vierde tijdcontrole, Hij wil natuurlijk met zijn loper naar b4 en dan met de koning naar a3. Met een onverschillig gezicht slinger ik de dame naar a5.

Pats!, daar raakt hij de loper aan, die hij direct weer loslaat. Onmiddellijk kijk ik naar de hulpwedstrijdleider-zettenopschrijver, die naast het bord zit en in het vroeg-ochtendlijk uur de enige is die in de verre verten van de enorme speelzaal te bekennen is. Hij zit de krant te lezen. Ik heb niet eens geprotesteerd. Men staat machteloos tegenover het kwaad, als men van allen verlaten is.

Ook krijgt mijn scherpe blik geen enkele respons van mijn tegenstander. Hij zit plotseling hijgend te snuiven, alsof hij zich gebrand heeft. Ik kijk naar zijn gluiperige handen. Zijn beringde en behaarde vingers, mollig en paars van het graaien in bloesjes en jongensbroekjes.

Na 88.Lb4 Dxb5 had zwart beter, zo niet gewonnen gestaan. Maar als hij tot rust is gekomen doet hij 88.Kc3-b2.

Nov-18-12  brankat: Over the years he did surprise a few big guns :-)
Nov-18-12  BIDMONFA: Miguel Cuellar Gacharna


Apr-18-17  Eduardo Bermudez: By February 1954, CUÉLLAR had reached a chessmetrics rating of 2623, good for #39 in the world. He had performed at 2665 at Mar del Plata 1953. With a 2600 performance generally denoting grandmaster standard, it seemed quite clear that CUÉLLAR deserved a promotion to the higher title, based upon least three strong results in good calibre events: 2627, at Mar del Plata 1952, 2665 at Mar del Plata 1953 y 2621 at Siegen Olimpyad 1970, with more than 50 chess games.
Apr-18-17  Eduardo Bermudez: "He defeated a number of top players in Interzonals, his victims including Efim Geller and Viktor Korchnoi (Stockholm 1962), Samuel Reshevsky, Aleksandar Matanovic, and Lubomir Kavalek (Sousse Interzonal, (1967))." In other events, he also defeat: Najdorf, Pilnik, Trifunovic, O´ Kelly,Bisguier, Szabo, Panno and Nogueiras, Yanofsky, among others.
