There are some interesting themes and subtle moves in the July 2008 Tactics Time.
Problem 1 is an excellent example of not making the obvious move. Here black’s queen is attacked, but he doesn’t just make a knee jerk reaction to move it, and instead finds an offensive move that is brilliant.
Problem 3 is a nice clearance, double attack theme.
Problem 4 is a nice mating net, that shows the importance of move order, which is something that class players often screw up. They have the right idea, but play the moves in the wrong order, often missing something subtle about the position.
Problem 6 is a nice Karpov style defensive move, that eliminates the opponents’ threats first.
