Baekthepoker AKA BTP is a bitch and has a fucked-up face so let's get down to raping him.
It is important to know Baek's move first so let me list down a few that BTP almost always uses:
D4333-This string is very annoying because it starts from a low and the last hit stuns for a crumple stun juggle should you attempt to counter hit him. However the mid is highly sidesteppable and is -16 on block but with pushback. It is possible for Baek to cancel the last hit of D4333 into FLA where he can do moves like FLA 4 and counter hit your ss launch attempt for a free juggle. Remember to not try to block low if the low hits you because you'll eat the whole string.
Df34- This move is a NC double kick to the gut that deals good damage and wallsplats. It is -13 and is delayable/hit confirmable but seeing as how retardedly fucking stupid BTP is, the second hit always comes out irregardless of anything.
FLA f2+3- Always be on guard for this throw, Baek only has this throw from FLA and it's a 1+2 break. He doesn't have a definite pattern for when he's gonna use this throw but there are a few I can elaborate on later.
B1- He's only started using this recently but I think I have to talk about it since it's a pretty annoying and good move. It's a -10? move that gives a breakable stun on CH and has a very evasive ss property. Since the general playstyle against BTP is turtling, It would be rare that anyone could get counter hit by it.
Ss3+4- 3 hit launcher which is -13 on block. Nothing more to be said except that you shouldn't be too hasty in whiff punishing it because I've eaten the third hit when it tried to whiff punish it in it's second kick animation. This is another one of BTP panic moves. Yes, he uses it even from range 3 apart.
B4- It's a funky looking kick that launches you for a BT combo. BTP only uses this once he successfully FLA ssed you. Even if you didn't whiff he will still do it and you can punish it. It's -12 so punish well.
FLA uf3- The hopkick from FLA with the ugliest sound in Tekken. -14 on block and is another one of BTP's random launcher/ 'whiff punisher' from FLA. If you get hit by this then get prepared for a beating down.
Db4- If you can't see this low then get prepared to be raped by BTP. This is a very important low to learn how to block because this is BTP only source of income when the opponent makes life hell for him. It's -33 on block so please make sure BTP die. It can come out from FLA too.
FLA db33- quick low high nc from FLA. He always cancels the second hit into FLA for more stringing so it's free launch if you blocked the db3.
There's not a lot of move that he uses but he can gimp lots of win from people because people don't understand how to get used to his antics so lets get down to his habits.
The habits listed below is 100% true and everyone should keep in mind of them in order to successfully rape the shit out of BTP:
After a jab punish, BTP will definitely FLA 90% of the time. I don't know why he does that too. HURHURHUR!!! Always, always use a tracking move after you jab punish. The only time when he won't FLA when you jab is when he fucking knows that you're doing a tracking move but just use it anyway.
One reason why BTP is so retardedly difficult to fight is because every unsafe move that you do does not translate into a punishment but a deadly d4333 mixup. Yes, he punishes unsafe move with d4333. I won't say for sure that he does this 100% of the time but random low parries after my unsafe move work sometimes. He punishes worst than me at SFIV.
His trademark move is d4333 so lets get into detail. The last hit of d4333 is highly steppable but Baek is able to cancel it to FLA and do FLA 4 to counter hit you. So what can we do? Even after reading this, you will still need time to adapt to his d4333 game because BTP d4333 game is very easy to read only when he fears you. Ok, so you should make an attempt to always ss the last hit until the point when he starts noticing you do that and cancels to FLA 4. This is when things become slightly complicated. You can either do a 10-13 frame move to interrupt his cancel attempt or you can hold b if you really don't wanna risk shit. OR you can be a hero and duck the 4 when he cancels but I seldom do that because I don't have to even do that to win. He has recently gotten used to my sidestepping and resorts to d4444 which is the low ender to gimp my health away but I low parry it because I can read his mind already. You have to play more and get your own VS experience to formulate your own tactics against his d4443 game. My formula is just a prototype which might not work for everyone.
BTP has a nervous disorder. Why? he can fucking do a launcher attempt like ss3+4 or FLA uf3 from range 3. If you're Zafina or anyone with a good long ranged launcher, make sure you whiff punish his ass. Golden rule is not to run over and attack but stay patient. Once you lose patience and start making mistakes, you have lost the battle against BTP.
BTP likes to crouch at the wall like all the scrubs do so you may do a wallsplat move since he can't punish. He doesn't crouch always though so you may have to do a few lows to train him to do so. Kazuya b12 might work wonders on him.
Patience and good defense is the key to winning BTP. Stay calm and remember not to pitbull. A very good character to fight Baek is Anna since df4 tracks the side where FLA sses to so I can do jab punish into df4 or df1 into df4. When he get's smart and tries to block, that's when you know he won't FLA ss so much anymore and you may start mixing up your mids. But still, you must watch out for the FLA ss. Anna ff2 also work wonders because it's a advancing tracking move.
Baek wall combo results in terrifying oki so I'll give a few tips on how to get minimal damage. His wall combo spikes you for a d333 and d2 mixup. D333 will hit you fully if you stay still or try to backroll/stand. However if you stay or sideroll then d2 karate chop will hit you. Anyway, just sideroll always because sideroll avoids the d333 and you can stand up to do your shit. Just eat d2 at times because d333 hurts. Meh, i don't care since i don't get launched by BTP anyway.
BTP uses df13 at times so you have to duck the second hit. I am lazy to duck his second hit anyway. Oh, he almost always does generic d1 jab after df13 because people like to hit back. Low parry or hopkick works wonders after his df13.
It's okay to lose to him for like 10 times, you'll prolly never lose to him again after you 20th loss so just relax.
So I'm done and after reading this, you can rape BTP with ease. The world no longer have to fear BTP anymore so cheers!
