Hello and welcome to episode 137 of the Thinking Elsat podcast in Vienna, Virginia. I'm Ben Olson and with me in Los Angeles is Nathan Fox. How's it going Nathan?

Great man. I just got back from the Bay Area. I was in Santa Clara last night doing a like promotional deal teaching logic games so that was fun and had the late flight back last night.

Cool. So I see my folks today. Okay. Yeah, they're down here. My dad's doing some like golf thing and my mom's just hanging out with him. So I'm going to drive down and see her for a while and then have dinner with them tonight.

Okay, cool.

Yeah.

So when you do the promotional games class, what do you, what games do you do?

I pick them at random. I really do. I just like grab some section of games.

So last night I was doing like something in the 60s. It was like from some games from 2010. Okay. Yeah. I like to do different ones that I haven't done a lot recently

if M's before P then H's before G. Mm-hmm.

Maybe it wasn't June 2010.

Anyway, the rule is if M's before P, then H is before G.

Yep.

And in the old days, I would have always like written out the rule and written the contra positive and all that.

And nowadays I just the first thing I do, it's like nothing even touches the paper besides a line down the middle

M before P on one side and P before M on the other side yeah yeah and it's amazing how much cleaner it is, how just, you just immediately are off to the races with that approach.

Yeah. Yeah, so then in the situation where the condition is met, you have the, um, the results or what was it, H before G, is that what it was?

Yeah, so on the side of the board where it's M before P, then I also have H before G.

And then on the other side, and I always like, you know,
