Was the value of thorn (“fawn”) pawns fully appreciated in decades past?

Many videos on YouTube channel "Kingscrusher" which discuss the play of new neural-net engines like Leela Chess Zero focus considerable attention upon the development of "thorn pawns" which are pawns that have reached the sixth rank and are blocked by a pawn in front but do not have pawns ahead of them to either side. In my limited study of the game in decades past, I've seen great significance given to passed pawns, but never any special attention given to thorn pawns. Do such pawns have a significance that has only been fully brought out as a result of AI-assisted research, or have they always been understood but simply not in things I'd read? Or is Kingscrusher giving them more significance than they deserve?



A typical thorn-pawn situation would occur when Black has pawns at f7, g7, and h7, white moves h5, Black g6, and white pushes h6. If Black has castled kingside, that pawn at h6 can be very hard to capture, and its presence kills the escape square at g7 and the possibility of easily establishing one at h7. Was that a common pattern in years past, and if so what was it called?

          I had never heard the term, but such pawns are very important for their contribution to certain mating patterns, the most famous of which would be Damiano's mate, which was included in Damiano's 1512 book Questo libro e da imparare giocare a scachi et de li partiti. Here's an archetypal example:



          [FEN "5rk1/6pQ/6P1/8/8/8/8/8 w - - 1 1"]

                    What visual should I use to simply compare current year value vs last year in Power BI desktop

                    Image
                    0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
