General Strategy
Forest's main goal is to get close to start his up close pressure game. You will mainly want to use strong movement to get close, and be prepared to counter poke or stop reckless advances with your magic 4. You can also use df+2 or d+4 to try and keep opponents out while making your approach.
Once you're within range, this is where the party starts. Keep yourself on the opponent with 1 jabs and df+1's, but remember to track those pesky sidesteps. Unfortunately, homing moves don't exist yet, so your main counter to these are either stepping with the opponent, or using a move that tracks somewhat, like df+1 or standing 4.
Once you've gotten your opponent impatient, hit their attempt to take their turn back with a quick magic 4, or do a sidestep into 3,4 for a massive launch punish. This is the main gameplay loop with Law, get in, get them impatient, punish with half-health juggles.
If your opponent is turtling up, no big deal. Check them ducking with df+1, check them standing with d+4, and you have a few great throws to test the opponent's throw breaks. 2+4 gives great okizeme, f,f+3+4 has a "guaranteed followup" in db+4 (it's only guaranteed if they don't tech roll the knockdown, but hey, good knowledge check!), and f+2+3 has a very distinct but wildly different throw animation than regular throws, making it either much easier or much harder to break on reaction.
If you're on the defensive, you're in no means out of the fight. You have fast jabs, great sidesteps, and a plethora of parries to steal back your turn. His Fake Step, b+1+2, is massively rewarding if successfully landed, and has a fairly generous active window. Be sure to follow it up with 2 for the launch punish!
Succeed in doing this, and you'll find Law to be a fantastic contender in this game of death. His fists of fury can take down even the toughest opponents, and by following the way of the dragon, you'll find yourself with an excellent character!
