Well, insofar as I have been summoned....

This is going to be a relatively basic answer, but a lot depends on the office environment and political culture where you work. There are two types of women in the office: Pre-Wall and Post-Wall.

For the Post-Wall/Mother Hen types, utilize "classic" Western chivalry. Hold doors, offer help if they are carrying something heavy, etc. They've become (or are in the process of becoming) unused to attention from men. You aren't gaming them, at all but just being helpful & nice, like your mama taught you. Like a bluepill. But you don't care about banging them, you just want them to like you, and say "He's such a nice man" and such.

Ex. Years ago, at a different gig, I happened to come into the office in the early evening as I sometimes do - nobody around to pester me, so you can get three hours of work done in an hour - and the HMFIC's admin was working on some huge project. So after just dropping buy to alert her that I was on the floor--women working alone at night can be a bit jumpy -- and exchanging pleasantries. so I wouldn't scare the shit out of her accidentally, I went about my business.

As I was leaving, I noticed she was preparing what appeared to be a rather heavy box, so without really thinking about it, I offered to carry it down to her car for her. Turns out it was a really heavy box, but I hoisted it on to my shoulder and off we went. Anyway, that was enough to get me onto her VIP list, and I didn't realize the extent that she had the ear of her boss, the HMFIC. Also, although I didn't know it at the time, as I was still something of a plebe at that point, she's a an office politician in something of a "Griselda Blanco" kind of way, and good at rewarding her friends and punishing her enemies.

For the Pre-Wall/Baby Chick types, you you want to run light game, but never give the impression that it's anything more than "in fun". Because HR doesn't have much of a sense of humor. Keep it light and fun, and stylish, not overt. A lot depends on who you are. I had a former boss who was a total perve towards women in the office, but he would get away with it b/c he was a white-haired, grandpa type. You could see women doing the math in their heads and he always fell above the age line; i.e., a younger guy would have gotten nailed for it. I'm late 40s so I can easily camouflage myself as a "Kindly Uncle" {N.B. as opposed to the "Creepy Uncle; it's important} when need be. Also, at this point I've been a "known guy" at work for nearly a decade.

There are of course, exceptions. If the young chick is an SJW or otherwise psycho, maintain a perimeter.

Also I work with an older lady, in her 50s who you can tell was smoking hot back in the day, and who many guys in the office would happily bang now. Even one of the gay guys. Or so he told me. Anyway, she and I have a very friendly relationship as we're both natural extroverts, and I'm good at greasing her deals through. A lot of the younger women in the office look up to her as a role model, thus she provides me with a TON of social proof as she's very flirty, touch feely with me in social (like after hours) situations.

Similarly, I used to work with a woman named "Maria", who was well-past the Wall, had four kids and had never lost the baby weight and had packed on a bunch more besides, and likely hadn't been railed out by her hubby since the first Clinton Administration. So as it turns out, I'm a singer, and she walked into the coffee room one day while I was pouring a cup and I sang the first few bars of "Maria" from "West Side Story". Now, clearly I was just being amusing, but it did make her whole day.

Do I do this from a Machiavellian perspective? Not really. I was happy to make Maria smile, and I enjoy the sales chick's company, in addition to the social proof she provides. Life is short and work sucks. Why not have fun? And if the fun pays dividends, so much the better.
