Win rate with optimal strategy against limit raise bot
Imagine you are at the casino and they have new game there (disregard that it would be -EV for the casino).
You are playing limit Texas Hold'em against a computer and all the computer does is just raising every hand until showdown. Questions: 1. What's the optimal preflop raise range? 2. What's the optimal postflop strategy? 3. How many BB/100 do you win with the optimal strategy? The opponent (computer) is absolutely predictable so an optimal strategy must be calculatable. If this is doable then one must also be able to calculate the exact win rate with this strategy. I hope there is somebody out there who is able to calculate those things and maybe even explain a little bit how they do it. AaronBrwon, pzhon? Is this maybe a lot harder to calculate than it seems? |

[/ QUOTE ] This is harder than it seems and you have very solid implied odds if he is raising every hand every street. |

Re: Win rate with optimal strategy against limit raise bot
The optimal strategy will depend on many things like the flop texture . Whether or not you should call a person down .

Re: Win rate with optimal strategy against limit raise bot
The winning strategy is very obvious.
Only thing that matters is that the bot is playing every hand so all you have to do is play every hand that has over 50% pre-flop equity against a random hand heads-up followed by putting max possible money in the pot on every street. As for calculating your win rate, I`ll leave that for others. |

[/ QUOTE ] This is wrong in several ways. [img]/images/graemlins/diamond.gif[/img] That you were ahead of a random hand preflop does not mean you are ahead of a random hand once you get more information. 33 isn't so good on a KKTT4 board. QJo is ok on a board of AAK97r (51% against a random hand), but not 97653 with 3 to a suit (6% against a random hand). [img]/images/graemlins/diamond.gif[/img]If your hand is worse than a random hand, you may be better off calling down rather than folding. [img]/images/graemlins/diamond.gif[/img]If your hand is worse than a random hand, you may be happy to call and see if your hand improves. Even without the ability to raise the bot, you would come out ahead with many hands by doing this. Less obviously, if you win slightly more than 50% of the time hot and cold, say with 98o on a JT2r board, where you win 50.4% against a random hand, you might not want to raise back and forth. You do not win the pot over 50% of the time when you sometimes fold unimproved, and you don't want to bloat the pot so that folding with 98o unimproved is a close decision. |

Re: Win rate with optimal strategy against limit raise bot
There are many situations where folding your unimproved hands is a mistake . If most streets are getting capped , then it may actually be correct , depending on the flop texture, to call down without having paired the board . If the decision to raise or call is close , then it may be correct to just call since there are times when you may fold unimproved .
The winning strategy is very complex and will have to be adjusted for every unique flop combination that comes out . Pre-flop is where it can get tricky . Since you're getting wonderful implied odds , it's often times correct to just call with inferior hands rather than fold . Hands that are close to 50% equity against a random hand have to be looked at and analyzed carefully . Something like q-5 o wins slightly more than 50% of the time when you get to see all 5 cards . If you cap it pre-flop and hit a pair on the flop then you may actually be reducing your EV if your opponent has 5+ outs with good implied odds . This positive EV situation may offset the EV you will have earned by raising him pre-flop . A question of interest is whether or not it's ever correct to fold before the flop . Folding is always 0 EV . On the other hand , you may call with a hand like 3-2 o knowing that if you hit a 2 or a 3 , then all streets will ( usually) be capped . This is actually a good thing as you gain some of the EV that you would have lost by calling with this hand btf . |

The times that you hit only 1 pair, you'll probably be good more than 50% of the time, and when you hit 2pair/trips/straight then you can cap it every street, and you end up getting 23:1 implied odds on your preflop call. |

[/ QUOTE ] Clearly my intuition was better than yours because you would come out ahead of ALL hands by limping with even 3-2 offsuit . Why did you say many hands ? Did you not think it was profitable to call with 3-2 offsuit? |

Almost a month later, you are trying to nitpick on this? Is that because you feel embarrassed about your implied odds nonsense? I don't feel the need to compete with you, but if I did, you'd lose. [ QUOTE ] Why did you say many hands ? Did you not think it was profitable to call with 3-2 offsuit? [/ QUOTE ] First, I wasn't just talking about preflop. See the other statements I made before the one you quoted. Second, I said, "even without the ability to raise the bot." That's an additional variation. It eliminates the trivial silliness about unlimited raises, which I don't think had been mentioned yet, but which I wanted to avoid. Third, even if my intuition had been wrong about that trivial point (it was actually correct), so what? I posted the main nontrivial point about this problem, with an example and an explanation, about 4 hours after it was posted. You haven't contributed anything similar to this discussion. So, what is your problem? Do you feel like you need to one-up me? If so, you failed, but you succeeded in annoying me. Don't expect me to help you again in the future, as I have several times in the past: ICM, sphere, etc. I see why most poker theorists don't bother contributing to this forum. |

[/ QUOTE ] Well at first glance I would think the best approach would be to play the upper 50% range of starting hands and max out betting in each round regardless of board. High variance, but it should be +EV. ~K9o+ |
