More Tactics: Carlsen-Bae from the Norwegian Championship - The Solution
On Thursday I offered this very interesting position from the Norwegian Championship, with budding super-GM Magnus Carlsen on the move, with White:



If you've worked it out, have a look here. Be warned: if you saw the game and know Carlsen's solution, you might want to look again - his move was very clever, but not the best!

Won in 60 Seconds: Solution Time
This was the starting position from a one-minute game played yesterday:



It's White (yours truly) to move; as I asked yesterday, what should I do about my rook? The answer is here.

Young super-grandmaster (Magnus Carlsen) has the white pieces and the move; what should he do with it?

Won in 60 Seconds
Let's start with this position, from a 1-minute game of mine earlier today:



How should White meet the threat to his rook? Solution tomorrow.

Grimshaws and Nowotnys - Solution Time
In the previous post, I described the problem themes known as the Grimshaw and the Nowotny, and offered these three positions by way of illustration:



White to move and mate in two.



White to move and mate in three.



Black to move and mate in four.

Solutions here.

Chess, Names, and the World Cup
Despite America's less than stellar performance, I've watched a reasonable chunk of the World Cup the past few weeks (congrats to Italy!). The game certainly has its own artistry (here I'm referring to both individual athleticism and the beauty of seeing a team functioning well as a team, not to the thespians incessantly taking dives and faking injuries), but this post will only superficially address soccer/football.

The extent to which I'll mention is that I saw two player names of interest while watching the World Cup: Nakamura (Japan) and Nowotny (Germany). I won't say anything about the soccer players, but only about their chess-related namesakes. It's likely that all or nearly all of my readers are familiar with American GM Hikaru Nakamura, but I suspect that few of you have heard of Nowotny (or "Novotny", as it is often spelled in English-language sources).

Anton Nowotny (1829-1871) doesn't even show up in the Mega2006 database (under either spelling), but he has made an important contribution to the aesthetics of our game by inventing - or rather, discovering - the problem theme now named for him. The Nowotny is a form of Grimshaw (that helps, right?), and a Grimshaw (named for Walter Grimshaw (1832-1890)) refers to a particular interference motif. The basic idea with a Grimshaw is that if the defender moves piece x to a certain square, in blocks the line of piece y, while if piece y moves to that square, it blocks the line of piece x. What the Nowotny adds to this is that the interference square is occupied by a White piece (in the typical problem case), so that the Black capture generates the interference.

Some examples might help, but I'll offer them in the form of problems to be solved. The solutions will come in a day or two, and by then all will be clear.



White to move, mate in two.



White to move, mate in three.



Black to move, mate in four.
