Endgame Queens

This isn't a difficult problem, but I believe I solved it without thinking why it worked.

A few minutes thinking about it afterwards has, I hope, cemented the reasons behind it, which are not just the threat of checkmate from White, but equally avoiding the checks from Black.


White to play
Solution if required [ 1.Qc3 Qb7 2. Qa1

Last Tactics Position, and minor musings on learning from CTB

At the end of this post, is the last position from Chess Tactics for Beginners (CTB ).

Time-wise, and reflecting my lack of obsession regarding a speedy completion of these, I have probably taken a comfortable 9 to 12 months ( in elapsed time ) to do this, with a boost last Thursday for the last 32 examples , some of which I repeated again this morning, since a midnight finish is not the most sensible.

The final position was straightforward, and not involving any technical things such as "opposition", "queening squares" or "shoulder-charging" or the like, just a simple calculation.

I don't think my particular version of CTB exists with Convecta/ChessOK any more, as they have been ' peshka-ising'  their old CD products for some time now.

I suspect that the nearest is now this, which is a 3-part product having approximately the same number of examples to solve ( 2500 ).

CTB was one of the products that was used previously in the chess blogosphere to try to emulate the 'de la maza' tactics splurge ( see here for one example ).  

[ The 'de la Maza' info is viewed statistically here and here by the excellent Empirical Rabbit blog and his story summarised by Heisman here ). ]

Repeating standard tactics a set number of times ( often, the magic number of  7 is mentioned ) was often an initial step in the 'Knights Errant' chess improvers, with a view that such positions were retained and used as a base for further improvement. It should be noted that the target time for completion of these repetitions was generally a lot less than the year I took for one :)

Pawn Endgame

The theme in this type of endgame is the pawn structure, or maybe more accurately the squares they can control from the rook file.



White to move


Once you see this, and play a few examples, it becomes very obvious, but I am sure that being presented with this in a game , especially with  limited time, it could seem like a difficult place to be.

However, the idea of the power of the doubled pawns , in conjunction with other blocks, is a useful tool to have and use.

More Radio Chess, Steve Davis and Magma

Hey, don't be turned off my the post subject, chess has little enough media coverage as it is, so any blip on the radar is good  !

The format in this series is a continuation of previous ones , where someone is interviewed over a game of chess about both chess, and their own 'sphere of knowledge/interest/fame', with GM Daniel King giving a rather banal commentary.

This time around there is a distinct chess presence as Garry Kasparov is one of those interviewed, but the series starts with Steve Davis.

Who's he ? asks a large number of readers ?

If you are a snooker fan you will know the name instantly, as he was World Champion in the 1980s, dominating the game for a number of years. His final in 1985 had an amazing 18 million viewers for the last game of the match ( a so-called 'black ball' game as the entire final eventually rested on the last ball of the the last frame). 

Davis lost it to Dennis Taylor, but sealed his place in sporting history.

Chess-wise, he was also a dedicated amateur ( best in his school, apparently ) , although by his own admission not a great player. 

He co-authored a couple of chess books in the 1980s with English GM David Norwood, both firmly aimed at the amateur.

Not a Smothered mate

Here's another CTB position, and no, its not a smothered mate despite so many pieces on the board and around the king.

Its also notable that there isn't a forced mate, although that is the solution given in CTB.

Admittedly, if you don't follow the given solution ( ie the reply from Black ) , then Black is on a fairly downward course, but technically, its not forced !

Its not a smothered mate either, or have I already said that ?  This mate is often termed ....


White to move

Solution if required [ 1. Qxf6+ Kxf6 2. Bd5#    and its an epaulette mate, I think ]

More tactics on a stifling theme....

As I trawl through CTB slowly, I find some interesting positions. 

Here's one related to a theme that I seem to enjoy.

Not that hard, but you'll probably dismiss the solution first time around.





Solution if required [ 1. Ng5+ Kh6 2. Rh7+ Bxh7 3. Nf7 mate ]
