That would mean doing a DDOS attack on a player; and I'm positive that's against the rules to discuss here.
Nowadays, a DDOS attack using proxies, and not bots, only works on horrible connections. Bots, you may ask, are computers you use to send information the the other player, bombarding his connection and shutting it down; ie: he leaves, you win.
To get bots, though, you need to infect other computers, say around 25-50, with Trojans; that's were I'm 100% sure you will get in trouble for looking for help here, and you should.
Only tip I can give you: Don't try it. 99.9% things you will find are just actual Trojans themselves, and you'll end up being someone else's bot without even knowing it.
Just play the game, jeez.
There's a bar at the start of each match that indicates the connection quality. I never join games that aren't green. You should try it.
