This positionwas possibly reached for the first time (in theelectronically recorded history of chess) inthe game played between two chess mastersof the past - Carl Schlechter and MikhailChigorin, in Berlin 1897, after atransposition of moves. Black had thenplayed the nowadays considered asinaccurate 4... b5, followed by 5... Lb7. Asin most main line systems of play, themiddlegame positions arising from this pointonwards prove to be highly entertaining,instructive and requiring imagination andfighting spirit. If wishing to playsuccessfully on a high level, one would ofcourse need to go through volumes ofexisting theoretical opening articles, such asis Chess Informant's legendary C78Monograph by GMs Alexander Beliavskyand Adrian Mikhachishin. A number ofleading Grand Masters worldwide continueto practice the Arkhangelsk. Leading Chess1Trainers offer it as training materials fortheir students, with an accent on the openingvariations and middlegames arising fromthem. What follows soon is a remarkable,unique, and most importantly - enjoyablemiddlegame checkmating exercise, which Ihad successfully used many times in chesstrainings with players (and trainers) ofvarious national and FIDE rating and FIDEtitle levels, inclusive of GMs.7.c3 Se4 8.d4!

Thepresentpositionfeaturesafirstrecommended classical training one ("Howshould Black proceed?"), with the trainerresearching (and documenting!) details oftalent and potential among trainees who havenot seen or analyzed this position before, aswell as being one inside a checklist, whentraining with higher level players.13...Ke7!13...gf6 was played at least five times in theperiod 1970–1992, with the most valuableonesbeingplayedbetweenGMsViswanathan Anand (2525) and AdrianMikhalchishin (2475) 0–1 (42), played inMoscow 1989, followed by GMs Patrick G.Wolff (2520) and Mikhail Tal (2565), in SanFrancisco (USA) 1991, which White won in55 moves. Wolff - Tal was also featured inChess Informant 52/335 (1991), analysed byWhite, who gave in the annotaion 13...Ke7an exclamation mark, followed by anobvious continuation 14. axb3 gxf6 withequality.

Back in1991, during Yugoslavia National OlympiadMen's Team group trainings, I offered thediagram as an analysis position with arequirement to four GMs to check if Whitehas winning chances in case of Blackaccepting the Rook sacrifice. TheArchangelsk was then very popular and,being National Coach, I was tasked by theplayers to find new ideas and ways for Whiteto improve on the existing theory fromWhite's side. One of the potential novelties Ihad then compiled lead to the position with14.Lg5, which I classified as an idea pendingfurther research. After a relatively shortanalysis, it was, however, concluded to my2initial disappointment that the atempt wasinteresting, but fails to produce a winningposition, with us quickly switching to othermiddlegame positions of analysis value.GM Wolff briefly analysed 14.Lg5, too (!)and awarded it a question mark, with thefollowing analysis published: 14...Sa115.Te1 Kd6 16.Lf4 Kc6 17.d5 Kc5!–+(17...Kb6? 18.Sd7 Ka5(18...Ka7 19.Le3+-)19.Lc7 Ka4 20.Sb6 Ka5 21.Sc4 Ka4 22.b3Sb3 23.Sb2#). You will notice thesimilarities between Wolff's analysis andconclusions, with the ones we had made,during team training, both having been madeindependently and presuming at a similartime on far away geographical distances.

The trainer'stask here is to request the student to find allexisting and unique fastest checkmates, inthe end proving White's mate in 12, in arestricted amount of time, up to one hourmaximum, depending on the current playinglevel of the student. Within group training,the points are to be given according to thenumber of unique checkmates found.Students names can then be documentedinside the solutions template below, at theend of each checkmate found, ultimatelycreating a database worth researchingfurther. The exercise should be done over achess board, and the variations written outby hand. Moving the pieces may be allowedfor levels below FM title or below 2300FIDE-rating.15...Kd8?? of course leads to a picturesquemate in one: 16.Te8#. 15...Le4 is Black'sbest try and not a part of the intendedexercise.
