Hello,

I have been playing around with Nexus before core openings, experimenting with both greedy eco and weird cheeses based loosely on Has.

One of my recent builds is 15 gate - 16 gas - 17 nexus - 18 core, where you stay on 1 gas in the early game to either rapidly ramp up eco, or do 2 base a Chargelot immortal all-in around 5:00.

I'm not 100% certain of the value of 17 nexus vs 20 nexus, though as I know 20 nexus has been the standard for a long time.

It appears I can get the nexus much earlier than normal this way, get core started by 1:30, and still end up with more workers than a 20 nexus at the 3:00 mark, but I'm not 100% sure of the math.

Does anyone else have experience with 17 vs 20 nexus? Would you be able to articulate the advantages of one, or state definitively which is better economy?

I remember that Harstem made some (somewhat sensationalised) videos covering these types of build:

18 Nexus vs. Zerg:

17 Nexus vs. Terran:

What are you transitioning to and what are the timings of various things off this opener?

It may be the case that by itself you can get better eco doing this, but in a match scenario end up with a worse eco by cutting/delaying certain things that your opponent can take advantage of

Your way:
https://burnysc2.github.io/sc2-planner/?&race=protoss&bo=002eJyLrlbKTFGysjDRUSqpLEhVslIqzy/KTi1SqtUhJGNmAJcpLikqTS4pLUolRpsRedoMydKGsCwxuSQzPw8uYWpJlnnmdHU9mUGM09PmCC2leZklCA04deCxxJB0PeTIkGMPvdxmhssa0iVMaSkRCwBWnzsE
29 Probes but two building probes are a combined 19/12ths complete.
744 mins and 432 gas in bank

Standard:

30 Probes but two building probes are a combined 10/12 complete. This means you are really only a quarter of a probe ahead.
838 mins and 420 gas in bank.

So Standard gives you an extra quarter of a probe and an extra 82 resources.


Your way starts a Cyber Core 4 seconds earlier so it might be better for fast tech.
