I agree a 100% with Ms. Divine (Bernice too). The cards near the Heart will let you know a bit more on how successful or careful the person is being, and likely with who (another man, another woman, several strings of lovers). I also agree in that the Jack is more like a passion than true love (though not always).
If I might also comment on the 36 cards... I'd like to underline that if you use the 36 definitions only, you'd need to add their negative meanings as well seeing as you should read the cards more negatively depending on the situation and cards surrounding them, so in fact you'd have at least 72 definitions. Add to that, various combinations that could precise the meanings even further.
