Now, here are the rules of SB...
SB is a style of forum roleplaying where two (usually two, sometimes more) users take characters they've designed and battle each-other with them. Everything's COMPLETELY described in words, and the key is to be descriptive as if writing a book. Essentially it's almost just like writing a book, or at least one part of said book, except that it's actually two people contributing to the same book, and at the same time you're trying to beat the other guy... though the point of SB isn't a whole lot about winning the battle; what's more important is A) having fun, and B) the creativity and plot aspect. (A lot of the time, characters who fight will develop certain relationships with each-other... My characters would battle my online friends' characters and become friends or rivals with them for example, for future fights. One of my female characters ended up in love with another guy's male characters. It can be pretty complicated sometimes if you let it be, and you know how I am with being creative, so yeah.)
This is how a battle generally goes. The first player posts how his character comes to be in the arena he's in... The post also has to describe the arena. The arena can be ANYTHING you want... Grassy field, forest, the city, or something a little more out of the box, like some ancient ruins, the inside of a clock tower, a dimensional space-time rift, series of big stone platforms floating miles above the ground, or anything else. ANYTHING. Don't forget about weather, it counts as part of the battlefield too. Weather can be creative as well... Doesn't have to be rain, or snow, a windstorm... Could be that the air is super-saturated with mana, or the battlefield is a volcano and there's an earthquake every few minutes, or something extreme like that. Of course the basics are just as important...
By the way, when you start a thread, you can either make a specific challenge to someone in particular, or an "Open Battle" where the first person to reply there is your opponent. This thread falls in the Open Battle category, meaning whoever replies first is my opponent.
Anyway, the post explains what your character is doing in that area, how he/she got there, etc. The second poster posts how his character meets the first character, or comes to that arena, etc. The next few posts generally are the two characters interacting in whatever way, and after that, one of them throws the first attack, and battle starts. (The "interaction" phase is sometimes very short and sometimes it lasts a while. It completely depends on the scenario in question. Sometimes it turns out to be a friendly spar, sometimes the two characters are really trying to end each-other's lives. But I try to make sure that nobody actually dies in any SB fights I take part in, and if they do, it's NEVER by my hand. Ever.)
From here on, the two players take turns explaining how their character attacks the other character, and deals with their opponent's incoming attacks and actions. The battle continues until one or both characters can/will no longer fight. Again, this varies. Sometimes one guy pounds the other into submission the old fashioned way, sometimes they both are too tired and decide to have a truce, sometimes one guy's winning but decides to give up because he admires his opponent, sometimes one guy actually saves the other guy from something (like his own attack, or a hazard that's part of the battlefield, etc.)... Again, possibilities really are endless. After the battle has ended, each poster takes a few turns to resolve the encounter and go their separate ways, or at least otherwise explained what happened to his/her character after the fight.
With me so far? Okay, now, the battle has some special rules. The main rule defines SB combat as what it is: You are NOT allowed to decide whether your attacks hit. The OTHER GUY does. However, the two players can't just avoid or block all the attacks they're targeted with and be invincible. Each player has to be realistic, and in a realistic fight against evenly matched opponents, both sides are generally taking hits. Give yourself some weakness. It might sound strange, but it makes the sport fun.
Another rule is "No Godmodding". And Godmodding is when you make your character all-powerful, or at least super-powerful with little to no weakness. One guy was fighting another guy once and his first attack was to summon Sephiroth who blasted the opponent into dust with one blast. That is serious Godmodding. One guy pulled a meteor down from space which hit the planet and sent it into an Ice Age. That is serious Godmodding. You get the general idea. It's fine to have super-strong attacks, but the thing to keep in mind is "High-level attacks need a drawback". The drawback can be something simple like it requires the user to charge up energy for a few turns (your post + the foe's post = one "turn"), or it causes the user some recoil damage, or it has a low accuracy... You could go with something a little more extreme as well. One guy fired a double shockwave at me that was hard to dodge and would deal amazing damage, but he couldn't use any special attacks after that for 5 turns, as an example. Some of my characters' attacks can only be used once per battle, as another example, or only when they're at low health. Some super-attacks require immense concentration and can be interrupted easily. You can be creative with your drawbacks.
Godmodding can also include using a lot of actions in one turn. You should try to keep it to one major action or attack and one form of defense per turn. So, like, I fire a needle barrage at you on my turn... You run towards me while zipping in and out of the needles, then leap into the air and deliver a heavily powered spin-kick, on your turn... Then on my turn I attempt to block the attack with my arms, getting knocked back, and retalliate with a straight punch followed by a left hook... That's how it works. (Of course there is always exceptions. Someone once made a character who's "gimmick" was that he could use two special attacks per turn, but was weak in defense and could be sent flying easier.
No controlling the foe's character. This is a big one. It ties into not deciding whether your attacks hit. You should NOT say "Kent slashes Rachael with his sword diagonally, knocking her to the ground, surprised. It does medium damage." You SHOULD say instead, "Kent attacks Rachael by slashing diagonally at her with his sword. If it hits, it does medium damage." (To simplify, "Slashing her" is bad, "Slashing AT her" is good. See the difference?)
There are two kinds of attacks that should NEVER be used. Healing is one. Teleportation is the other. Teleporting makes it too easy and cheap to dodge attacks. Healing makes the fight either take forever or be totally unfair, depending on whether or not the opponent can also heal. I had a character once that could heal, but he never used it until after the battle was officially over. Then he always healed his opponent, to show his honor.
Last rule. Your character doesn't NEED to have a Profile. That Profile thing is completely optional.
That about does it.
This is basically like the thread Schwa created, with two twists. Before the game starts, I need an opponent. The next person to reply is my opponent.
The second twist is that your character doesn't have to be a creation of your own. It can be a real life person, or a character from a video game, or anything (I think you all can guess my choice. .
