Reminds me approach that you get in nearly every book on "How to meet girls".

Systematic, efficient.

Played this game myself. And I did it when moved to the US with a limited English and lack of understanding of the local culture and traditions.

After a few years of dedicated practice, moved me from the state that author describes to the complete lack of fear talking to strangers, I can easily make nearly ever conversation warmer, deeper and more relaxed.

A couple more comments, based on personal experience:

[1] It works better if place where you meet is your deep comfort zone, a very familiar place

- gym, if you are going there for some time, know where each type of equipment is. - dance venue that you were going dancing for a while - art class - etc

[2] It helps a lot if you are quite proficient in the activity, expertise brings respect, and higher social status by itself, even when you do not talk to anyone.

[a] in the gym ideal technique > strength > looks / size of your muscles.

- Third class in powerlifting, based on Soviet grading system is a threshold, passing which life changes (question of months, maybe a year). You get more respect from men and curiosity from women, and you get more confident, because you got stronger: https://www.sportscategory.info/en/powerlifting - As your shoulders get broader, fat fat percentage goes down - it improves your appearance -> your confidence -> helps as well.

[b] Dance venue is a great place to meet people and address your fears / issues. Rule of the game - during the class before the social part teacher makes you switch partners => you will be forced to introduce yourself to the partner, this person cannot turn away and will need to reply, introduce themselves.

Later when social part starts - people switch partners every dance => - you start with inviting for a dance people whom you already met during the introductory class. - In 3 hours of social dancing you dance with 20+ people - As your skill grows (question of weeks-months) and dancing with you is not torture anymore, but quite the opposite - it is enjoyable => you get more relaxed, people want to dance with you => conversations start all the time - In dancing, as a man you lead, and this transfers to other activities (helped to become a lecturer teacher in University), but you also better lead the conversation. I.e. it is not a random exchange of information anymore, but you can vary it's direction and emotional component.

--- [3] Some places are better than others.

It is good to go to the gym, to get more friends, but not directly. I do not like talking to people in the gym, I suspect that other people as well.

you are recovering between sets, focussing on the audiobook, moving weights - you are always busy with something. I also heard that women do not like talking to men in the gym as they may feel "no in the best form", i.e. for her - talking to men feels comfortable, when she took shower, picked a cloths that fits her, not when she is sweaty, struggling with weights and sees other ladies in the gym who are more fit.

Places like:

- climbing gym <- very social activity where you solve same problems - trying to climb a route. You can just tell someone who struggled to climb a bouldering problem something like: "Nice!", "Good job!", "Well done", and ask for a tip.

Ot if you already climbed it - give a tip yourself. These are natural openers.

If you climb similar level of problem, you will get stack in the gym in the same spots, taking a break between tries - universe will force you to talk and socialize.

- Dance venue, as I mentioned above - Hikes - any types of group classes: scuba diving, wine tasting, art classes, etc will do the job quite well
