Henrik Juel: Popeye 4.61 with 'opt thr 1' found no flaws (2020-11-04)
James Malcom: I've managed a small extension, so do not computer test this yet. (2020-11-04)
Olaf Jenkner: Semi-finished problems should not be published. (2020-11-05)
James Malcom: I agree-this was a severe lapse in my judgement. (2020-11-05)
A.Buchanan: I think you’re being too hard on yourself, James. It’s hard to know when a problem is “finished”. Unless a position is just thrown together for a discussion, I tend to wait another sleep cycle to see if any more ideas pop up. But it’s not the end of the world if an electronically published problem gets improved a couple of days after the first post (2020-11-05)
James Malcom: I had had the previous position for a while now, but only yesterday did I see how to improve it. And the new position has now been entered. There are definite duals in the sidelines, but there is a forward, main, defense plan for Black. (2020-11-05)
