No one gives up in blitz | Abdusattorov - Kovalev | Ruy Lopez endgame

Sometimes players fill better playing with black in a blitz game as they may have clearer counter play. In this game Kovalev slowly outplayed his opponent and got decisive advantage. Still you have to know your abcies.
Nodirbek Abdusattorov - Vladislav Kovalev, Aeroflot Blitz, Ruy Lopez defence, Moscow, 2020
At the most basic level, White's third move attacks the knight which defends the e5-pawn from the attack by the f3-knight. White's apparent threat to win Black's e-pawn with 4.Bxc6 dxc6 5.Nxe5 is illusory—Black can respond with 5...Qd4, forking the knight and e4-pawn, which will win back the material with a good position. White's 3.Bb5 is still a good move; it develops a piece, prepares castling, and sets up a potential pin against Black's king. Since White's third move carries no immediate threat, however, Black can respond in a wide variety of ways.

Traditionally, White's objective in playing the Ruy Lopez is to spoil Black's pawn structure; either way Black recaptures following the exchange on c6 will have negative features, though recapturing gains the bishop pair.[3] In modern practice, however, White does not always exchange bishop for knight on c6, preferring the retreat 4.Ba4 if chased by 3...a6.

The theory of the Ruy Lopez is the most extensively developed of all Open Games, with some lines having been analysed well beyond move thirty. At nearly every move there are many reasonable alternatives, and most have been deeply explored. It is convenient to divide the possibilities into two groups based on whether or not Black responds with (3...a6), which is named the Morphy Defence after Paul Morphy, although he was not the originator of the line.[4] The variations with Black moves other than 3...a6 are older and generally simpler, but the Morphy Defence lines are more commonly played.
