Sicilian Attacks with Black : Tactics Quiz !

The previous post featured a nice sicilian game won by GM Ivanchuk in his last game against Cheparinov in the M-Tel 2008 tournament.

Here, we present 4 tactical training positions. There are all issued from the Sicilian Defence, and all feature a tactical idea leading to the victory of the black pieces. Please note that a previous post showed an attack from Kasparov in a Sicilian Scheveningen against GM Michael Adams in Linares 2005.

The roster in this quiz includes games from GMs J.Polgar, Delchev and V. Ivanchuk (again!)
