To conclude the studies section, a position by Chéron which is a correction of a study by Kéres

W.: Kd7, Bf3, pg2
B.: Kf4, pa6, g5 and h4
To be dug in depth to extract the substantive marrow.
A little diversions into the real world with the game of the day between two fighters .
4 - game of the day
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. 0-0 Be7 6. Re1 b5 7. Bb3 d6 (no fashionable gambit this time, just classic) 8. c3 0-0 9. h3 Na5 10. Bc2 c5 11. d4 Bb7 12. d5 Nc4 13. a4 (13. b3 Nb6 14. a4 Bc8 15. Qe2 Bb7 has also be played) Nb6 14. Qe2
Nxa4 15. Bxa4 ba 16. c4 Nd7 17. Rxa4 Nb6 18. Ra3 a5 19. Nc3 a4 20. Be3 Bc8 21. b3 ab 22. Rxb3 Ra6 23. Reb1 f5? 24. Bxc5 !? dc 25. Nxe5 Na4 26. Nxa4 Rxa4 27. Nc6 28. e5 Ra6 29. Qf3 ?! (29. Nxe7+ Qxe7 30 e6 with a lasting advantage) f4 30 Re1 Bf5 31.
Rb5 (threatens Qb3 then Rb7) Fc2 32. Rb2 Bg6 33. Rd2 Be8
(33. ... Bg5! 34. e6 Be7! 35. Nxe7+ Qxe7 and Black is rather well) 34. Nxe7+ Qxe7 35. d6 Qe6 36. Qb7 Bc6! 37. Qxa6 Bxg2! 38. f3! 39. Kh2 Bg4! (both players are top class madmen on 39. ... Rf6, White would have played 40. d7) 40. Qb7 (White hesitated for a long time on the continuation 40. hg Qxg4 41. Rf1 f3 42. Qa2 Qh4+ 43. Kg1 Qg3 44. Rg2! Qxg2+ 45. Qxg2 fg 46. Rxf8+ Kxf8 47. e6 g5 48. e7+ Ke8 49. Kxg2 h5 50. Kh2 and you get a winning study position that you still have to master) Qh6 41. Qd5 Rf7 42. Kg1 Qxh3 43. Qg2 Qh4 44. Rf2 f3? (44. ... Bh3 =) 45. e6 Rf8 46. e7 Re8 47. d7 Bxd7 48. Qxf3 Qg5+ 49. Kf1 resigns
A superb killer fight.
During dinner, a few problems were presented by two of the guests, but not knowing whether the compositions are published or in the process of being published, the greffier, in spite of all the aesthetic pleasure felt during the resolution, could not afford to present them in the report. The Master has brought out of his bag, the digestives arriving on the table, 2 problems by Peter Harris whose reputation as a composer of men's positions is well established.
Beware, it's brutal
5. h#2,5 ultra-patrol Anti-Andernach
helpmate n moves : black plays and helps white to checkmate them - with n,5, white plays first and we end up with an helped n moves
ultra-patrol : a piece (or pawn) can only play (and a fortiori capture) if it is under the control of a piece of its camp
Anti-Andernach : a piece (or pawn) changes colour if it does not capture
W.: Ba7, pb6 and c7
B.: Ke5, Qa8
a) position of the statement
b) remove Ba7
Have some more, here's another one
6 - h#4 ultra-patrol super Andernach
super Andernach : a piece (or pawn) that moves (captured or not) changes colour (except King, of course)
W.: pa5 and b6
B.: Ka8, Qc1 and c8
Some concentrate quite complicated to get in mind.
It's a long way to Peter Harris
So much for this first session of the year, which saw the advent of the kitchen Grandmaster (many thanks to him)
As the participants are hot, the next class will take place on Tuesday to avoid getting soft.
Have a good read.
Sincerely yours
