Wow......it's a wonder you beat a Pokemon at all. Not that you can't, but with only a 1751 3rd Gen Pokemon as your strongest......you may get fucked pretty hard if someone REALLY decided to troll and place a Chansey, Blissey, Snorlax, or Dragonite near you.
Check out this website to check for IVs and junk, also, it has a pretty accurate (within 5%, which is amazing) battle simulator where you can calculate chance of you winning given and opponent.
