GTA Online Diamond Casino Heist Setup Guide: Approaches

I don't want to take up too much time from anyone reading this, as it's the 50,000th post about Inside Track. I'm just very bitter towards R* lately (removing the red dumpster from Stab City Survival was a vindictive, petty, asshole move and my last straw) and I want people to be able to game their system and not have to waste real life money on Shark Cards.
There isn't going to be much in the way of elaborate explanations or mathematical breakdowns here, just a dry list of my soft "rules" which enabled me to go from 20,000 chips to buying my Casino Penthouse in one day.
For starters, bet smartly. You can only take 20,000 chips from the teller every 48 minutes, so going broke is inconvenient. I would say start with 2,000 chip bets, maybe go up to 5,000 on "likely wins" (I'll point those out in a second) until you hit ~80,000 chips so you have a buffer. Then you can start making the 10,000 chip bets.
As an extra incentive, while I've been typing this I've been betting again, and I've made $300,000 in profit so far. It only took me about 45 minutes to finish this post.
Okay, so:
1: There is no strategy that works 100% of the time. Certain scenarios have a high chance of success, but you WILL lose on "safe" bets sometimes. That's okay. It'll still be profitable in the long run for you.
2: Play single events. "Main" events have no advantage to them, you have to wait 5 minutes to play one, and I have had a glitch for months where the 6 horses have been the same during every main event until I reset my GTAO session, but the winner is different each time.
3: R* has removed the ability to "reset" the race lineup by exiting out of the computer screen. Unless you have the patience to restart GTA every time you end up with a bad set of horses, it's easier to just power through bad races. You'll win some of them, and even if you don't, 30 seconds later you'll have a new race!
4: Most of my bets are on horse #1. If you don't want to utilize the more complicated strategies below, betting on #1 every single time should be profitable for you, just at a slower rate. This is not a new strategy of course, but it's worth mentioning. I find that when I get shafted with a bunch of really poor horses (e.g. Sir Scrambled, Tax The Poor, Better Than Nothing), #1 generally wins the most by a slight margin. Horse #1 still tends to work out well for me even when I end up with a bunch of horses I like. If I end up with a race where Horse #1 ALSO has (or ties for) the best odds, my win ratio for betting on Horse #1 is >95%. In short, if you find yourself in a scenario where you have no discernible "safe" bet, just go with horse #1 unless it's a TERRIBLE horse.
5: Some horses are absolute trash. I have run HUNDREDS of races, and Clapback Charlie, Tax The Poor, Wage of Consent, Feed the Trolls, Tea Ache Sea, Night-Time Mare, Stupid Money, Dead Heat Hattie, Better Than Nothing, and a few other horses I'm forgetting, have all lost every single race they were a part of. Several others have only won once or twice, but the aforementioned horses literally have a combined total of 0 wins in my entire time playing. I don't bet on these horses even when they're horse #1.
6: Of the very high odds (e.g. 30/1) horses, Old Ill Will and Money to Burn are the only ones I've had a decent number of wins with. A Tethered End has won for me a couple times, but I find he only wins in the #3 position under specific circumstances (see rule #11).
7: The main instance for me where my "bet on horse #1" strategy is overruled, are races where there is a horse with "EVENS" odds. I know, "EVENS" bets are really tedious and earn profit at a crawl, but they have the highest win percentage. No, they don't win every time, but it is much more profitable to bet on them every time they appear - regardless of outcome - than to play guesswork as to whether or not "it'll win/lose this time". If horse #1 has "EVENS", bet on it no matter what the other horses are. I think I only lost two times out of all the times I bet in that particular situation. If more than one horse has "EVENS" but neither one is horse #1, I generally bet on the one closer to the top (e.g. if horse #3 and horse #6 are both evens, I'll pick horse #3).
8: As a follow-up to the last tip, my ranking of the "EVENS" horses (for when you have to choose between them) is Sumptin Saucy > It's a Trap >> Total Belter >> Salt 'n' Sauce >>>> Snatched Your Mama >>> Dream Shatterer >> Lit as Truck.
9: The BEST horse is Omens and Ice. I have won nearly every race with him. I have a literal 100% win percentage when Omens and Ice is horse #1. The best thing is that he has 3/1 odds, so it's not as much of a crawl betting on him, and he is definitely VERY profitable. He overrules every other "rule" for me, no matter which # horse he is. He is the ONLY horse, of ANY odds, that I would pick over Sumptin Saucy. Outside of the "EVENS" horses, the rest of my top 5 horses are Lead is Out (3/1), Robocall (4/1), Hell for Weather (2/1), and Downtown Renown (4/1). Some of these horses seem to be more reliable than some of the EVENS horses.
10: If you find yourself in a situation where all of these options are unavailable (e.g. shitty horse #1, no EVENS horses, no Omens and Ice), I would generally just bet on the horse with the best odds. If NONE of the horses are ones you like, even the best odds ones, then go with #1 as per usual.
11: This is a VERY specific scenario, but if horse #1 is a trash horse, but the horse with the best odds is horse #6 (let's say it has 2/1 odds), and then horse #3 has slightly worse odds (e.g. 3/1 or 4/1), I actually find that horse #3 wins more often. This is the only scenario where I deliberately bet on #3 specifically, other than when it is an "EVENS" or specific horse. I have also sometimes had success doing this even with long-odds horses like A Tethered End.
12: If horse #5 and horse #6 BOTH have the best odds (e.g. both horses are 5/1 and all other horses are 6/1 or worse), one of them is probably (but not always) going to win. I generally bet on #5 every time for the sake of consistency, but I find it's pretty much a coin flil.
13: Don't panic! If you find yourself on a losing streak/war of attrition, ride it out. The ship will right itself. It just might take time. I hit 1,000,000 and then fell back down to nearly 700,000. But I kept going, and eventually I was up enough to buy my penthouse.
14: Take notes or memorize as much as you can about your races. Use your intuition. You might pick up on a pattern, good or bad, with a certain horse that I haven't noticed. Look at all 6 horses every single race before you bet. Using my tips and your own judgment, carefully pick the one that you believe has the best chances whenever possible. It's better to only win 10,000 on a "safe" pick than to lose it on an atypical, unlikely victory.
15: This is not "fast" money. It's relatively "easy", but unless you have incredible luck, it will take you at least a few hours to end up with a good seven-figure sum of profit.
And that's about it! I hope this helps some people, especially newer players, in making some extra coin.

Ever since R* announced that the recent update was part one of a potentially multi-piece series of updates, a lot of us have been thinking about what the next part of the update could potentially be. Personally, I don't really like the update; it's shallow, with nothing but a few cars, worthless planes, some clothes and a new gun. However, what I'm hoping is that the next part of the DLC is much bigger and better than what we got in this part.
The title of the DLC is "Ill Gotten Gains", and we've already seen the criminal parts of the ill gotten gains; the supercars, the flashy new gear. If you think about it, all the new stuff is what Crooks spend their money on after pulling off a Heist or 5. What I think is coming up next is the flipside of the coin, the other party involved in Ill Gotten Gains; the Cops.
It's something people have wanted since Gta 4's fundamentally acclaimed Cops 'n Crooks gamemode that mysteriously has yet to make an appearance in GTA 5. Why is that? It seems like a pretty simple thing to add in; 2 sides, one objective each (However, it did take R* a year and a half to add in 5 Heists, so perhaps I'm giving them a little too much credit). However, if you think about it, there's been a couple of instances where players have found ways to either store Police vehicles or obtain Police uniforms, and have then either had these methods stopped or in the case of the vehicles, deleted. This is pretty odd, unless you look at it in 2 ways.
1, Rockstar are a bunch of spoilsports that don't want their playerbase to have fun using glitches or playing the game in ways they did not intend (Yes, I know they've done this in the past, but hear me out!), or:
2, Rockstar has been saving this stuff for a big DLC, one that allows players to purchase all sorts of Police themed clothing items and vehicles. Think about it, you're able to purchase a number of Military vehicles including Tanks, Jets and even trucks and jeeps. However, vehicles such as the Police Cruiser, the Police Buffalo, the Police Maverick, the SWAT Granger and the SWAT armoured truck are all off limits. Isn't that odd? Plus, players were free to purchase nearly every single item utilised within the Heists. All, except the Police Uniform. Players are free to imitate Military personnel, including soldiers and Pilots, yet it's rather difficult to find anything that closely resembles an LSPD uniform.
Of course, this is all baseless speculation and rambling coming from me, but a little discussion never hurt, did it? What do you think? What else could R* be hiding up their sleeves for the next part of this DLC series? What other criminal stuff is there? New houses? The Casino?
