I have that classic book of Tartakower too.AdminX wrote:Interesting yet speculative sacrifice from Tartakower. I was not familiar with this game. I own a copy of his classic 500 Master Games of Chess. I wonder if this game is in there. Anyway here is my output on mobile.
Tartakower analyses the game in another classic: "Die hypermoderne Schachpartie", starting on page 404.AdminX wrote:Interesting yet speculative sacrifice from Tartakower.

I found the game on page 556 (Game#429), I will go over Tartakower's analysis later in the day. I guess its time to dust off "Old English Notation"!MikeGL wrote:I have that classic book of Tartakower too.AdminX wrote:Interesting yet speculative sacrifice from Tartakower.

I remember this game being included on that book. It was written by Tartakower and this game is a classic k-side attack of Tartakower.
