Solid like a rock :+)

This is what we call the critical moment. White has taken risks but is on known territory. Black has defended correctly. He is holding his position, perhaps he is a bit better, however, the lack of time and the practical aspect of the game play a factor. A defence must be found.

20.- b5 (I have, for a long time, analysed 20...Kg8, it’s surely one of the lines to explore in order to defend this position) 21.Bxb5 Be7?? (a big mistake. Vishy begins to tire and loses the plot of the game. 21 . . .Kg8 was still possible. In fact, by anticipating white’s attack, black prepares a counterattack.)
