  Mateo: A long theoretical variation in the Alapin played at the highest level. Morozevitch played 15.0-0 against Lautier and drew. Rozentalis, Adams and Ponomariov 15.Na3, with a poor result: 1 draw, 2 losses. Stellwagen defended well but made an inacurracy on move 39 (39...Bd5?! instead of 39...Kc7 impeding 40.c6) and blundered on the last move before time-control. 40...Bc4?? (he should have played 40...Kc8). After 41.Bb6 Kc8 42.Bc4 Bd8 43.Be6 Kb8 44.c7! Bc7 45.Bc7 Kc7 46.Bf7, White wins.

I thought most people call such a move a "zwischenzug", the German variant? I at least call it that way.

  patzer2: <EmperorAtahualpa> Apparently you're not alone in preferring the term "zwischenzug," as this is the term used in the online "chess dictionary" at http://www.angelfire.com/games5/che...:

<Zwischenzug (a.k.a. intermezzo): A German term meaning "in between move," it is a tactic in which a strong move interrupts an expected sequence of moves, altering the course of the game (for example, a check interrupting a series of exchanges).>

A very nice <ZWISCHENSCHACH> (in-between check) by Tiviakov.

Position after 41 Bf2-b6+! <zwischenschach>

If White had played the obvious recapture 41 Bb5xBc4?!, then Black would <BLOCKADE> the passed White c6-pawn with his king after 41 ... Kd8-c7.

Instead Tiviakov played the stronger <ZWISCHENSCHACH> 41 Bf2-b6+!, -first- gaining time on the Black king to gain control of the important c7-square in front of the passed pawn, and only -then- does he recapture his piece on c4 with 42 Bb5xBc4, not 41 Bb5xBc4?!.

Now White has regained his piece -and- prevented Black from <BLOCKADING> the passed pawn with his king.
