Time and Space- Sacrificing Material to Gain It!
The second game is the first game of the World Championship Match between Frank Marshall and Emanuel Lasker in 1907.
In this game, which is quite instructive,
Lasker sacrifices a piece, and Marshall is forced to return it. In the ensuing position, Marshall is also forced to exchange Queens, which leaves Lasker with an enduring positional advantage in the endgame, plus the initiative!
"CROSSING THE EQUATOR"
This is the term that David Bronstein used when a pawn is crossing the middle of the board. In the next game, Alexander Tolush makes an imperceptible mistake, which Bronstein exploits, showing its tactical weakness. No wonder they called Bronstein "cunning Devik"!

Bronstein comments about the following game:
"When I prepared myself for this game I noticed that in his game with Semen Furman a few rounds earlier, Lev Polugaevsky had gone after the pawn on c5. Would he do it again? I found that this plan had a flaw-too many moves with one knight and it it just not worth a pawn. when he repeated this line in our game I was very surprised. I did not repeat Furman's mistake, who defended the pawn on c5, and by sacrificing it, I got several extra tempi and could chase the White pieces away from the centre of the chessboard."
The following game is the one Polugaevsky refers to in his notes:
This blog would be incomplete without Bronstein's win against Keres in the 1955 Gothenburg Interzonal Tournament. This game won the First Brilliancy Prize!
The next game is a beauty...Blackburne sparkles!
Which reminds me of a similar e5 pawn sacrifice, with a similar pawn structure, played by Lasker against Capablanca, in their encounter in St. Petersburg, 1914!
