Great question, never heard any comparisons between the two. Heard of people playing other games including chess and transition to poker.
Both games are of strategy, with chess you see everything going on, there are no hidden varables. Poker your always trying to figure out what the other players have by numerous methods. Besides looking ahead to what going to happen further along, really is there any tangible transferable skills?
Sure preparation and evalutaion of past play are important, but that can be seen in anything you do. Just don't see the correlation between the too but I do enjoy both games.
