📘 Black is threatening to take back the strong pawn on d6 by playing 10...e5
10.Nd4!+/- is the only move that prevents black from playing e5.

📘 Tal has great lead in development, and as a result he should react drastically to realize his temporary advantage. After 10.f5? Bxf5 there is no clear way to continue the attack and 10.Kh1 is blunt. The correct continuation is to start an attack by:
10.Ng5! Bxe2 11.Qxe2 h6 12.Nxf7! Kxf7 13.f5!
with a fierce attack.

🔸Aronson,Lev Abramovich
🔸Tal,Mihail
🔸Moscow 1957

📘 26...Ne6?! seems strong but fails to 27.Qd6 and black can hardly find a move to claim advantage. For instance, 27...Bb1? is a mistake in view of 28.Bxe6 Rxe6 29.Qxf8+-.
The seemingly good 26...Re2?! to invade the second rank does not yield any advantage for black as other black pieces can hardly join this rook.
The best choice is 26...Bb1. By this move, black blocks Ra1, to enable himself to invade the first rank. By emptyig the f5 square, black is also threatening to play 27...Ne6 and respond 28.Qd6 with 28...Qf5!

📕 Black must realize the moment and play 18...h5! immediately; otherwise, white can consolidate his position by playing h3 and then either moving his rook away h file or playing Be2, leaving black with a number of structural weaknesses without an acceptable compensation.
