I'm interested in collections of chess problems where we are not told beforehand what is happening in the positions presented, but we have to decide by ourselves, whether something clear exists (a winning or drawing combination, a good move or plan that keeps the initiative) or whether the position presented is still unclear. Clearly the goal is to exercise judgment by simulating actual play.
So are there collections of problems of this type, in print or online?

Clearly the goal is to exercise analysis, intuition and general judgment of positions, by simulating actual play.
