While I hate UTG straddling, as putting in money blind in terrible position just doesn't seem profitable, if a casino lets you straddle from any position (giving priority to worst position), is it optimal to straddle your BTN 100% of the time assuming your table allows it...Or is this something that should vary based on your table?
Like if you have very passive villains in the blinds while you are on the BTN who don't play back at your steals, the advantage of buying position preflop is not worth it; but if you have aggressive villains on your immediate left you should be straddling? Also should stack sizes be taken into account?

Also, what about straddling the CO? It seems like this would put the BTN in a tough spot, as they have to act first preflop and will actually have to play much tighter preflop, effectively letting you get two buttons per orbit, assuming the rest of the table is letting you straddle whenever you want.

And if you are on the BTN when there is a CO straddle, what adjustments should be made to your preflop opening range?

I'm not sure these are scenarios that come up for a lot of players, but there is a casino near me that allows straddling from any position and I was thinking about what the best strategy was. I don't play there often, but when I do I straddle the BTN as much as possible because it seems extremely advantageous to have position both pre and post.

I don't like paying money to play 72o, no not even if it's from the button.

EDIT

I guess if I'm playing a table full of simps who are all straddling, then I'm happy to go along with it. Then I don't know whether it's more EV that everyone straddles UTG or from the BTN...I guess I'd probably rather UTG so they make the nutworst action 9x in an orbit.

Button straddles tend to make the blinds play tighter.. Ie make less preflop mistakes.. HJ or CO straddles however seem like a pretty good move based on what you've outlined re taking the button/co position outnof the mix using the same reasoning they shld play tighter with the straddle on giving you an advantage in those spots.. I play in a game where u can straddle from any position so if i miss my blinds you can either just post in as usual for 15 or you can straddle for 20 (its 5/10) so when i come back in either of those two positions i always come in for a straddle rather than post...

I'd be more likely to straddle if the blinds are passive. Aggressive players might raise me with a wider range because they know I'm likely to have nothing. And in some rooms the blinds don't act first if there is a BTN straddle; they act after everyone else except the BTN.

Passive games are games the BTN straddles work best in. Passive players just call the straddle with wide ranges and usually fold if the straddler makes a big raise. If the passive players "stand up" to the raise, they call PF and then play fit or fold on the flop. LOL at that.

Most of the casinos where I play have stupid straddle rules. Like the Venetian, where action starts at the same UTG (BB + 1) when the button straddles. And then there's the issue of what happens when someone raises before you act. It's beyond me why the casinos (esp. a "reputable" room like Venetian) would want to ruin their games, but they do.

A legitimate analysis would require a better explanation of what exactly happens when someone straddles from MP. E.g. if you straddle from CO, can the button re-straddle, and what happens if the button raises?

Putting money in the pot blind is rarely a good idea. A button straddle is just simply a less bad idea than a UTG straddle.

In theory playing higher stakes when we have position postflop should be +EV.

However a) straddle makes game play less deep so if there are shorter stacks we sometimes will minimize our postflop edge. B) bad players in blinds as mentioned often end up playing correctly (ie folding) since the have to act first. C) if we make -EV plays just cuz we haz the straddle obv it's not profitable.

Mb I'm just an action freak. But I love the "Dallas straddle." Pretty much hand plays out the same but with the straddle having ultimate last action. That's almost like cheating. If there's a raise and a re-raise you get to see everything go down, before you act. I love it.
I'm more apt to do it the deeper I am.

Only one person can straddle, no re-straddles. UTG gets first priority, then UTG+1, ect. So if I tried to straddle from the BTN, if any other player besides the blinds decided they wanted to straddle they could and I would have to pull mine back. Pre-flop play then starts from the left of the straddle. If the BTN straddles the pre-flop action starts on the small blind.

Assuming you're a good player, I would guess you should UTG straddle anytime someone in LP does.

Why? A good player should have a low Vpip from utg. Let's say it's even as high as 20%. For every 5 orbits you put in an extra bb for 4 hands you should muck.

This, but no one will listen because wizard.

Why would BTN straddles make the blinds play better? The BB often gets to check when there is no straddle. Straddling forces this player to make some calling and folding errors (instead of just checking when he normally would). Also in some rooms the blinds still act in late position before the flop. As for the SB, I'd expect this player to make a lot of calling errors because "hey I'm still getting a discount." This is especially true in rooms that have the SB act after everyone except the BB and the BTN (when the BTN straddles).

straddling makes people play more loose. If I have bad players who have at least 150bb I'll be pretty much straddle every time. I see a lot of people call straddles with marginal hand and then get sucked into calling a late position raise because there's "omg so much money in the pot" mentality of the passive fish.

Maybe so, but only one fish raised before he even saw his cards.

That is such a good way to put it. I legit lol'd.
