This acutally goes for most champs. If you want to win top lane then you need to learn zone control and proper warding to help you not get ganked. Most strong top lanes are better off not trying to rush a tower honestly but use it to force the other top lane in staying around to get zoned. If their jungler comes to help push you out try and use your edge of farm and level to make them both pay for it. If you can't win don't give a free kill but rather force them both to take enough damage to go B. This lets you once again get the free farm and level advantage. Simple stuff.
