>fy_iceworld’s buyzone rests obliviously in the center of the map in a dangerously cramped no man’s land.

>This placement makes it extremely difficult to spend any money, which basically blocks off Counter-Strike’s central progression and loadout system while creating this funny risky incentive to rush into the middle before the buytime closes. 95% of the time, you’ll just get gunned down from 3 different sides. But if you’re lucky, you can run in, buy a grenade, and toss it into the other team’s spawn, and it feels like you’ve gotten away with something.

Not quite. You'd bind your buy script to a key, and after your team killed the last enemy you have a few seconds to run there and hit that key. You keep the grenades in your inventory for the next round.
