You can find out about about every summit that has been part of SOTA by using the list and find summit features.
On either database application, from the menu select Summits then Find Summit. You then enter enough info about the summit to find it… that could be a partial or full name or partial or full summit reference. I typed ‘Poker’ and pressed find and a list of possible summits was returned.

So VE6/BK-017 Poker Peak was a 2pt summit that was invalidated on 1st July 2016. I don’t why but probably new data became available that showed it no longer met the criteria for inclusion in VE6 summits.
So it was valid but not any more.
