I had a huge post written out for this, but by the time I clicked "Post Quick Reply", it told me to relog and everything was lost rofl

Long story short, I'm not that great myself but have you tried a basic opening (like 3 gate) into expand into big gateway push? Keeping up with the zerg ecomony is really the key I think. Obivously if he's one basing you can just stick to one base to, although expanding at some point it always better. Fancy 2-gate zealot pressure or voidray openings don't work that well after the zealot build time increase and the voidray damage nerf.
And as already mentioned, post replays, easier to help that way. IMO most players look for mistakes in the wrong parts of their gameplay.
