Yeah gotta go with CH FRA. I don't think any human could do much against CH unless they have a gun. Even if we removed CH's prior knowledge of you, they'd still think absolute circles around you. To quote Jesse Pinkman "Whatever you think is supposed to happen, I'm telling you, the exact reverse opposite of that is going to happen", and given CH's INSANE knowledge, they'd probably come up with some superhumanly complicated plan to take you down that you could never see coming in a million years
With CH's knowledge of the building, extreme intelligence, and probably the senses to spot any trap you lay out, I think they'd just predict or spot every trap you try to lay out & manage to get close to you, in which case it's ggs
With the equipment that you do have in this match, your best bet would be to use the gasoline to burn down the building. But there are a few problems with this. Mainly:
- CH would smell the gas
- You risk burning yourself to death
- CH, with the knowledge of every firefighter, would probably know how to survive & get out of a burning building
Fireworks & Firecrackers won't do much here, I've been extremely close to a firework that went off & I'm still here, so CH could do the exact same. Also, aiming & firing fireworks as an offensive tactic likely won't work too well against someone with CH's reaction & combat speed, in addition to Analytical Prediction & Instinctive Reactions
Unless you have like legit military experience or training in setting up traps, I don't think that you could take CH down. Honestly, I think hardly any humans could take CH down with the specified equipment & prep time
However, give yourself a gun and you probably win assuming you have a powerful gun & decent aim
