|Sally Simpson: Hi SpiritedReposte,
Sadly because Lombardy missed it then it cannot make the POTD.

I'd rank it a Tuesday/Wednesday puzzle because if you have seen the idea before and 'KNOW' there is something on then you look for tactics and there is very little else on the board to suggest a tactic except that pawn on the 5th rank. "...can I get that pawn through?"
The only other tactical element worth looking at is the Black Rook which is defending the Bishop, it is short of squares (it has two) a check on d8 will reduce that to one.
But there is no way to hit the Rook. However hopefully thinking along this line will get you too spotting the Rc6 idea.
It's one of them. You will get within a minute (even shorter) or if you have never seen the idea before then you will struggle to the point of thinking the diagram has been set up wrong (they very rarely are...stay with it.)
If it cropped up OTB. One would have to rely very strongly on the gut feeling kicking in and even then acknowledging that your brain has spotted a familiar face in the crowd.
In Solving you are told there is someone here you recognise.
OTB you not told when to scan the crowd, you are hoping your trained gut feeling alerts you to a critical moment.
I have to say there is 99% chance I would have missed it OTB. I'm being generous with my 1% but I have seen the idea before so hopefully I would get a '..wait a minute....STOP!" signal that I'd recognise.
This was the third game of a training match organised to get Reshevsky match fit for a match v Bronstein to take place in December 1956. The match never happened in the end due to political unrest.
This game was being played whilst the first one was adjourned. I do not know the time controls but the fad at the time was 40 moves in 2½ hours so Lombardy could have been (pure speculation) in T.T. on move 37.
Apparently the weather was hot...very hot.
