From: Jackie Meyer ECE NEU EDU> Date: 25 may 1999 Subject: bogin defense In _How_to_Defend_in_Shogi_, www.vega.or.jp/~patrick/shogi/, Oyama analyzes as follows: (diagram below) 1. P-7f 2. P-8d 3. P-2f 4. P-8e 5. P-2e 6. G-3b 7. G-7h 8. P-8f 9. Px8f 10. Rx8f 11. P*8g 12. R-8b 13. K-6i 14. S-7b 15. B-7g 16. S-8c 17. S-8h 18. S-8d (moves up to here unknown, I just guessed them) 19. G-5h 20. S-8e 21. P-2d 22. Px2d 23. Rx2d 24. P*2c 25. R-2f 26. P*8f 27. P-7e 28. Px8g+ 29. Sx8g 30. P*8f 31. Sx8f 32. Sx8f l n - g k - s n l s - r - - - - g b - p - p p p p p p p - - - - - - - - - - - P - - - - - - - s - - - - - R - P - B P P P P - P - - G - G - - - - L N - K - - S N L PPP Now Oyama gives 33. Bx8f, saying that 33. Rx8f leads to an unfavorable semeai for Black after 34. Rx8f 35. Bx8f 36. R*2f 37. R*2b 38. G-7a. This last move is a finesse before playing 40. Rx2i+. Oyama does not mention how White would handle 39. S*6b. After the silver drop, I figure that Black has won; White's rook will not invade the Black camp (P*8g) and Black has such severe threats (P-7d). So White should have played 38. Rx2i+. What am I overlooking? Regards, Fred "Jackie" Meyer
