There are a lot of different play styles that, in the long term, could net you profit, although I guess there are situations where there is for sure a best play. Is this an IQ test based on what type of play you should make in a given scenario. or is it a test on your poker knowledge (like what type of hand is A B C D E, etc). And I would not take it too hard, IQ tests in general are not true indicators of intelligence (a slight correlation but not one that truly quantifies the vast definition of intelligence) and so I doubt that poker IQ would be a true indicator either. Let your past profits and awards do the talking in that respect.
