CBM Blog: The Troitzky Line

5/3/2011 – This is not a route on the Moscow Metro but a technique to solve a rare and difficult ending: two knights vs a pawn, which, you may or may not know, is winning if the defending pawn can be blockaded on or behind a certain line on the board. This was proven by the great endgame specialist A.A. Troitzky and is explained to us by GM Karsten Müller in a recent game. Very instructive.

Rook endings are always drawn But over the board this is much more difficult than in the analysis:

The Troitzky Line

The endgame two knights vs pawn probably does not belong to the standard mating procedures you need to master. But I found the following example so instructive that I could not resist the temptation to analyse it. Black's pawn has crossed the Troitzky-Line a4-b6-c5-d4-e4-f5-g6-h4, so that drawing and losing zones for the defending king exist. In this case it is imprisoned near the dangerous h8 corner so that White can win:

The Elephant Gambit

The Elephant Gambit (1.e4.e5 2.Nf3 d5!?) has never really been given the attention it deserves. It is a very useful surprise weapon. Let us list the advantages of playing this particular opening: 1) Shock value 2) It is very aggressive. Black can take over the initiative early. 3) Many tricky lines 4) Unorthodox. Black is basically taking the game to the opponent as early as move two. Not many openings do that! It's a perfect opening for young players and club players to adopt. Let Andrew Martin select a repertoire for you on this 60 mins, which, if used with discretion, will rack up the points. I am sure that you will enjoy this unusual tour of the Elephant Gambit.
