  Dionysius1: Fiachetto openings were quite common in Indian chess reported by the colonialists in the 19th Century. It was because traditional Indian chess had not allowed a pawn's 2-square advance, so there was more understanding of taking control of the centre on the diagonals initially.

  Korora: Isn't soma that powerful drug from <Brave New World>?
Jan-03-23  goodevans: Strangely, it would appear that <both players> missed <36...Qf6>, Black on move 36 and White two moves earlier when he moved the wrong R to c1.

Surely Black would want to get rid of White's b-pawn (you know, the one that made it all the way to the 7th rank to put him in a bind). 36...Bxb4 isn't possible because of 37.Rc8 but getting the Q off the back rank and at the same time attacking all three of White's pieces would get around that nicely.

There were plenty of mistakes in this game but to my mind missing 36...Qf6 was the most obvious of all and both players seem to have done just that.

Jan-03-23  goodevans: <Korora: Isn't soma that powerful drug from <Brave New World>?>

It was indeed and before that it was a ritual drink in ancient India, which is probably what inspired Huxley to use that name for his dystopian drug.

Given the negative connotations of 'Soma' in Brave New World it's a little surprising that it's been chosen as the brand name for the modern musculoskeletal pain drug Carisoprodol.
