Demoman Vs Demoman:

1. Introduction
Demomen rule. Too bad there are other demomen in the world. A demoman who is using pipebombs will almost always win, but then again keep in mind that you should shoot a grenade if you have the chance, since a direct hit will do a lot of damage.

2. Strategy
1) Bridge Strategy
If they have piped the bridge, depending on where they are, you can either try to throw a grenade or pipejump over the water.

2) Ramp Room Strategy
Simple. If the enemy is standing on the 2nd floor guarding, you can hit him with pipes. If you are on the 2nd floor and the enemy is coming right up to you through a ramp, shoot a grenade directly at him.

3) Basic Everywhere Strategy
USE PIPES. Important. If you can get a good juggle off (shooting them into the air) you can win the match. Be sure to also use your normal grenades.
