71_My_Alekhines_Block
Compiled by whiteshark
--*--

What is Alekhine’s Block?
= = = = = = = = = = = =

< Alekhine’s block is

< a chess combination

< with a piece sacrifice

< (Knight, Bishop, Rook, or Queen)

< on the 6th rank (3rd for Black).

>>>>>

It’s used for the first time by the former world champion Alexander Alekhine in 1910 (--> Alekhine vs V Ostrogsky, 1910 and here: --> Alekhine vs Gutkevich, 1910).

The idea is to physically restrict, or block the enemy pawn in front of the attacking piece (thus Alekhine’s “block”). As Nimtzowitsch put it, <“First restrain, then blockade, finally destroy!”>

This tactical device is just one implementation of the general strategic principle we need to follow in chess (see a previous post on restriction). Actually, in both, attack and defense, we want to put the brake on the enemy pieces and reduce their fighting potential either to attack our army, or withstand our attack being in progress. We want our pieces to stay unrestricted, or break free if restrained (there are several ways that we may restrict the freedom of movement of pieces and we will cover them in upcoming posts).

A dialogue: ...

frank124c: <whiteshark> I beg to differ if u don't mind. "Alekhine's Block is the sacrifice of a piece on the 6th--or 3rd--rank, near the castled King, the idea being to break up the enemy's castled position and to block his defense at the same time." I am quoting now from my own website at: http://mysite.verizon.net/webmaster...

Why is this not an Alekhine's Block? What is ur definition? I would like to hear from other readers as well--is this or is this not an Alekkhine's Block?

= - = -
<frank124c> I've check in Charushin's book, and you are right.

However, I'll take the liberty to (re-)define <my <Alekhine's block>> more restrictive as a non-taking, blockading move.
