Ancient default rounds aren't about occupying territory but about borrowing passage. Donut acts as a vision relay, B tunnels as collateral from A pressure, and caves as a time buffer. This article breaks down the logic of passage rights and how to create asymmetric advantages.
On Ancient, many players' first instinct in default rounds is "take mid first, then split." But recent scrims and reviews have convinced me this approach is backwards. The core of Ancient's default round isn't about taking map control—it's about borrowing passage. Mid isn't territory you need to hold; it's a passage right you lend out to Donut, B tunnels, and caves. Whoever utilizes this passage right well can secure an asymmetric 3v2 or 4v3 around 1:15, instead of five players crowding mid and staring at each other.
1. Donut Is Not a Site Entrance, But a Vision Relay
Let's start with Donut. Many treat it as A site's backdoor, assigning one player to camp at the entrance waiting for opponents to walk in. This turns a "relay station" into a "terminal." Donut's real value is that it simultaneously covers three information surfaces: mid slope, A main exit, and cave direction. Standing in Donut isn't about waiting for a fight—it's about collecting rent.
My suggestion: in the first 20 seconds of a default round, the Donut player shouldn't rush inside. First, take a "narrow sightline" from the wall outside Donut—expose only half your body to watch mid slope, and use a smoke to block A main's close angle. This smoke isn't for the opponent; it's to "reduce information" for yourself. You don't need to know if anyone is at A main; you only need to know that mid slope can't be crossed. This turns Donut from "a point to defend" into "a vision window you can lend out," allowing mid players to push toward B tunnels confidently because Donut is watching the slope behind them.
One detail: don't fully close the smoke at Donut—leave a gap. The purpose is to make opponents think you're defending, while you use the smoke's edge for "sightline arbitrage"—you can see feet at the edge, but they can't see your head. This gap is more valuable than a full smoke in default rounds because it makes opponents hesitate for two extra seconds, and those two seconds are exactly the time for B tunnels to borrow passage.
2. B Tunnels' Passage Right Is "Loaned" from A Pressure
Now B tunnels. Ancient's B tunnels are narrow; in default rounds, sneaking in alone is basically a death sentence. But if you understand it as "collateral from A pressure," the logic changes. As long as two utility pieces land on A—a smoke at A main and a molotov at Donut entrance—the B tunnel defenders will instinctively shift half a step toward A. That half step is your passage right.
Specific approach: from 30 to 45 seconds in the default round, two players on A create a "fake contact"—no real fight, just throw utility, make a footstep sound, then immediately pull back. At this moment, the B tunnel player moves in, don't stop, walk to the middle of the tunnel then stop. The stopping position is key: stop at the "attenuation inflection point" where you can hear footsteps inside B site but opponents can't hear yours. This point varies by map; on Ancient's B tunnels, it's roughly slightly past the middle. You can find it by walking through it twice in a workshop map.
Once you find this point, the B tunnel player becomes a "silent borrower": he doesn't take the site, he only pins B site players in place. If opponents move, you hear it; if they don't, A has one less rotator. That's the benefit of borrowing passage—you don't need to win B, you just need to make B uncomfortable.
3. Cave's Time Margin Is the Default Round's "Buffer Account"
Finally, cave. Many treat cave as A's third attack route, crowding three players at the cave entrance waiting for smokes in default rounds. This mistakes a "buffer account" for a "main account." Cave's role in default rounds is to give you "time margin": while Donut and B tunnels are borrowing passage, the cave player doesn't need to do anything—just stand in cave and let opponents know "someone is here."
This "someone is here" information is cheaper than any utility and more effective than any utility. Because once opponents confirm someone is in cave, one of A's rotation paths is cut off, and pressure on B tunnels automatically eases. The cave player can even throw nothing, just walk back and forth at the connection between mid and cave, creating the illusion of "ready to come out at any time." This illusion buys 10 to 15 seconds in default rounds, and 10-15 seconds on Ancient is enough for B tunnel players to complete a silent reposition.
Closing: The Ledger of Default Rounds
Putting these three lines together, Ancient's default round is actually a clear ledger: Donut lends vision, B tunnels lend pressure, cave lends time. None of these lines aim at "taking map control"; they aim at "making opponents make one more wrong decision." By around 1:10, you should have a 3v2 local advantage, a pinned B site, and a cave that opponents haven't read yet. Only then does discussing which site to hit become the real business of a default round.
If you've picked up an Ancient tactical map or a team's default round demo on C5GAME, don't just look at where they hit in the end. Rewind to the first 40 seconds: who's borrowing passage, who's collecting rent, who's keeping margin in the account. Once you understand these three things, Ancient's default round is no longer "five players in five positions" but a replayable system of passage trades.
