CHECK MATE!!

Note the following from my recent January 20 post, Check Mate:

• -Ion Rațiu ( 6 June 1917 – 17 January 2000)

• The key word is "chess".  Other notable persons mentioned on the Chess wiki page:

• Richard Réti (28 May 1889 – 6 June 1929)

• Viktor Lvovich Korchnoi^[3] (23 March 1931 – 6 June 2016)  

The Deaths in 2017 site lists under January 22:

• Cristina Adela Foișor (7 June 1967, Petroșani – 22 January 2017, Constanța^[1]) was a Romanian chess player, and an international master.

Keep in mind, that the birthday of Trish MacGregor, another key player in the inner twin worlds "Starr Family Production"...and fellow blogger is is June 7.  Hence we now have a "_,June 6(x3), 7, _/ pattern-cluster.  Note from Cristina's wik I page:

• Her daughter Sabina-Francesca Foisor is also chess player and Woman Grandmaster
• Sabina-Francesca Foişor (born 30 August 1989)

Sabina's birthday together with the birthday of Megan MacGregor (daughter of Trish) and another key player in the inner twin "Starr Family Production" generates an "August _, 29, 30/Date Sequence" pattern-clulster.
