I had never heard of this game.

Great kudos to CG.

Pun Counselor: "Is the title of this game, 'Ok Corral', an actual Pun?"

Pun Investigator: “No sir, the title, 'Ok Corral' has the last name of one of the players and thats all that we can discern at this point”

Pun Counselor: “Is the title a play-on-word?”

Pun Investigator: “No sir“

Pun Counselor: “Can the title be described as a rhyme, malapropism, idiomatic construction or anything like that?”

Pun Investigator: “No sir, not as far as I can tell”

Pun Counselor: “Thank you, Is there anything at all that the viewing audience can grasp onto for entertainment purposes or anything amusing at all regarding this title?”

Pun Investigator: “No sir. FYI & FWIW, The player, Jesus Diez del Corral has the last name of an actual corral that existed in Tombstone, Az in 1881. This was the 'Ok Corral' where a famous Wild West shootout occurred 135 years ago. Of course, there were many corrals all over the Wild West; and from what I understand, the actual 'shoot out' was nowhere near the Ok Corral, but this all probably means absolutely nothing”

Pun Counselor: “Thank you, but thats irrelevant. So, can we conclude that there is no pun, there is no play-on-word, there isn't even any rudimentary rhyme, or any off-shoot reference or for that matter, there isn't anything amusing at all, is that correct, in your opinion?”

Pun Investigator: “I would say so, yes. From what I can tell, yes sir, there is nothing here to define a pun or any of the other types of word-play you described and as you state, nothing amusing, nothing entertaining at all whatever.”

Pun Counselor: “Is there anything you would like to add sir?”

Pun Investigator: “Yes sir, In my opinion, a chess game of this quality does not deserve such an illogical, nonsensical, obscure, idiotic, and/or irrelevant title. In fact, no title is warranted at all for such a grand game of chess.”

Pun Counselor: “Thank you sir”
