This one is the same as one already appearing mirrored left-right:



So I've eliminated it and moved the other one to the good ones.

14 to be eliminated, the new additions look solid so elimination is getting harder.

One more, a mate in 24 from yacpdb:

I did not check this one for multiple solutions yet, and I suspect Bh2+ also wins.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Thanks for checking.
OTB, I would have had a hard choice between b6 and Bh2+ (both of which are fairly obvious looking), but it turns out only one of the moves has any merit.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.

Yes, many of these moves aren't impressive by themselves, what is impressive is that they're the only ones that work.

Give the previous 47, the total is 47+22=79
So if we eliminate the 15 least desirable positions, that gives 64 (the goal count, IIRC).
Previous best + remaining candidates:

What is the winning line for this position. I Can't seem to find the win after forcing bm Rgxf4, but surely an impressive draw.
Is there a winning line I missed or this is really a White To Move and Draw.
I told my wife that a husband is like a fine wine; he gets better with age. The next day, she locked me in the cellar.

You have to analyze longer :wink:
I have here +3 after the first two halfmoves.

It took me an hour.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
