In Episode 1 we started working on certain defensive skills. These entailed finding the way to stay out of 'trouble for the rest of the game' in difficult positions. Unfortunately there is no easy recipe to pinpoint these moments or positions in the game. In general: whenever you see or feel trouble lurking at the horizon and the position offers various choices or options, most probably this is such a moment!As advocated earlier: you then try to go for an active solution, if possible. Almost always this requires precise calculation.I still owe you solutions to 2 exercises from the first article. Let's start with them.

Alert Defence - Part 2 The position after 21.hxg3 is not as simple as it might look. Can you

[ 1...Bd5 2.c4 f6 3.cxd5 ( 3.Ng4!? ) 3...fxe5 4.Rd2 is possible, butcertainly not equal ]

[ 1...f6 2.Nd7 Nxd7 ( 2...e5 3.Bc4+ Kh8 4.Nxc5!; 2...Rfd8 3.Rfd1 Bd54.Nxf6+ gxf6 5.c4 only make thingsworse. ) 3.Rxd7 Rf7 4.Rd6! Re75.Bc4

demonstrate your defensive skills asBlack?This may look drawish to you, but ifWhite controls the d-file, chases theNc5 and invades on d7, we'll speakagain. How should Black avoid such afuture? Candidate moves are ...f6, ...Bd5,...Rfd8, ...Rad8. Let's see: 1...Rad8
