Information from the Chessbase website:
Before you can strike in chess – best by delivering mate – first you have to threaten something. And precisely this is the central theme of George Renko’s new CD – threats. With more than 2.500 selected tactical positions, the sheer amount of material is enormous. There are no lengthy introductions; without further ado, you can immediately start solving tasks until the cows come home – there is no better way to improve your tactical vision. The tasks are sorted according to themes, but of course you can also load one by using random selection.
