A porn star has promised a top Russian chess player the night of his life as his “Queen” if he wins an ongoing challenge against the reigning world champion.

Russian grandmaster Ian Nepomniachtchi is currently battling against Norwegian player and Chess World Champion Magnus Carlsen, 31.

And a saucy porn star going by the handle Mihanika69, who boasts a whopping 64,800 followers, posted photos on her Instagram in which she can be seen holding a sign saying: “Ian, if you win, I want to be your queen for whole night.” (sic)

She captioned the post: “Try to guess how much I love chess”.

She posted the photo with the hashtag #NepoGambit, which was previously introduced by figure skater Evgenia Medvedeva as a sign of support for Nepomniachtchi, 31.

But so far Nepomniachtchi is not winning. After eight games of the match played, he lost to Carlsen with a score of 3:5. The last encounter between the rivals ended in victory for the Norwegian.

According to the latest information, the Norwegian is currently leading 6-3 in the best-of-14 title showdown, with him having won for the third time in four games, opening up a massive lead.

The battle for the title of world champion is taking place in Dubai, with the first of the matches taking place last Friday, on 3rd December, and lasting seven hours and forty-five minutes, reportedly the longest game in the 135 years of the world championship.

The Norwegian won, as he did on Tuesday evening when he beat Nepomniachtchi in a little under four hours.

The next couple of games will be key and could lead to the Norwegian crushing the Russian early and successfully defending his world champion title.
