The above position occurred in this game, and Dr. Beckwith's play looks good:

[Event "Barbados vs USA Games"]
[Date "2004.05.31"]
[Round "3.1"]
[Black "Farley,C"]
[White "Beckwith,R"]
[Result "0-1"]

1. 10-15 21-17 2. 11-16 17-13 3. 16-20 25-21 4. 8-11 23-18 5. 7-10 26-23 6. 4-8 30-25 7. 9-14 18x9 8. 5x14 22-18 9. 15x22 25x9 10. 1-5 29-25 11. 5x14 25-22 12. 3-7 22-18 13. 14-17 21x14 14. 10x17 18-14 15. 17-22 {above diagram} 14-9 16. 22-25 9-5 17. 25-30?{F} 5-1 18. 7-10 23-19 19. 30-25 19-16 20. 12x19 24x15 21. 10x19 1x10 22. 20-24 27x20 23. 19-23 28-24 24. 25-22 24-19 25. 8-12 10-14 26. 2-6 31-27 27. 6-9 14x5 28. 23-26 27-24 29. 26-31 32-28 30. 11-16 20x11 31. 31-27 24-20 32. 27-24 0-1

F - In the match book, I wrote, "6-9 may draw." Let's examine that, and 11-16 is also candidate move:
F1 - 6-9 (7-10 or 6-10 seem to lose, after some study) 13-6 2-9 5-1 (24-19 or 23-18 may be strong) 9-14 (9-13? 1-6 WW) 24-19 ( or 1-5 WW) 25-30 1-5 14-17 5-9 17-22 23-18 (now or soon) WW (White wins), using reasonable care.
F2 - 11-16! (looks like a draw after a couple hours of study, but continue) 5-1 7-10 (others lose) 23-18 8-11 18-14 10-17 1-10 25-29 10-14 17-22 13-9 22-25 14-18 (14-17 or 9-5 are also strong) 25-30 18-23 29-25 9-5 (or 24-19) 25-21 (2-6 loses) 24-19 (5-1 may also win) 30-25 5-1 25-22 1-5 22-17 (retreating into the single corner loses in the same way) 5-9 17-13 9-14 13-17 14-18 2-6 19-15 WW, wins a piece. That wasn't easy.

Red's (Black's) problem was mainly in the weak pieces away from the single corner where he kinged. In note F1, those pieces were weak, but not as weak. There are similar endings in my book, Corner Classics.
