Well, that is a bunch of bull$#!+ on Kalinichenko’s, whoever Kalinichenko’s publisher’s, Convekta’s, and ChessBase’ parts. That sucks for Renko. If I were him, I’d publish my own Encyclopaedia of Combinations and dare those b!+€3$, Kalinichenko and ChessBase (throwing Renko under the bus, and not selling his program anymore, while Convekta continues to giving credit and profits not to Renko), to come after me.
ICT-1 is really good actually for tactic pattern recognition. For advanced 2000 chess.com players , who already had done years of simple tactics, will find it beginner stuff.
