 Pot Odds Calculator, JasonHoldEm, 20. Feb 2003 21:22 | ||

| Hi everyone, First off, this is NOT a commerical post. I'm a senior in college, studying software engineering. I've been playing poker (hold'em) for a little under a year now, and like most beginners I was struggling to understand pot odds. It's strange how something so simple can be difficult to grasp. Anyways, I was bored so I decided to write a little program that would calculate pot odds and the odds of making your hand, and then offer advice based on the two. The program is for hold'em, you simply input which round you're on (flop or turn), the number of outs your hand has, the size of the pot, and the size of the bet you need to call. Then you press calculate and it tells you what your pot odds and odds of making your hand are, and then suggests whether to call or fold. Right now, the calling/folding part is pretty basic, it will tell you to call anytime your pot odds are better than the odds of making your hand. I'd like to improve it to include advice for raising, bluffing, etc. but I need to do some more research on when those actions are appropriate (any tips?). Originally, I was going to make the option avaiable to calculate pot odds on the river, but elected not to...I'll probably add this once I figure out when it is appropriate to bluff (as obviously your hand can't improve at this point). I'm making the program available (for free), if anyone is interested in trying it out and giving me some feedback. I have it uploaded to my yahoo briefcase, but unfortunately for anyone to access it I need you to give me your yahoo ID so that I can add you to the list (yahoo doesn't allow public sharing of files for free). So if you're interested please drop me an email (jasonholdem@hotmail.com) with your yahoo ID and I'll add you to the list and send you instructions on where / how to download it. I like to think of it more as a training tool than a "crutch", by using it I've gotten better at doing the calculations in my head (although it's not automatic yet). With some more practice, I think it will become second nature (which will be nice when I sit down in a live game and don't have my computer with me). Take care, Jason | ||

| Jason- Great idea. You will get the hang of calculating in your head pretty quickly, so keep at it. My thoughts on enahcement (for raising) would mean having to quantify your position, the number of players in the pot, what "extra outs" you may have, the strength of the other players in the hand, and the action that has taken place in the hand so far (I am sure that there are others, but these are a few). For example, if you have the nut flush draw with two overcards, that might be a good time to semi-bluff raise (both for value and on the off chance that you can win it right there). So, I think the bottom line is that it would be hard to quantify these things for the program. What you might do would be to run some MC simulations to determine the factors where you have +EV by raising with a drawing hand and then incorporate those into the formula. Anyway, its a great exercise as is, so I encourage you to continue to pursuing it. Steve | ||

| The problem with a Pot Odds Calculator, and Pot Odds in general is the uncertainty of whether or not your hand will win even if it is made. Suppose you're playing A-J offsuite in Hold Em and you call a preflop raiser who was under the gun. Everyone else folds and you call. The flop comes over K J 2 with rainbow suits. The pre-flop raiser bets, now what does your Pot Odds Calculator tell you? Including his bed after the flop there are now 5 small bets in the pot, but what a calculator doesn't tell you is what he's holding. If he has KK or JJ you'll have to catch A+A or Q+10 runner runner to give you either a full house or a nut straight. If he has pocket 10s you're already in the lead, or he could be holding Q-10 suited and he's betting on speculation. The other day I was holding Kc-10c in a multi-player pot. The flop comes over 9c 2c Qh. I'm first to act after the flop and I toss in a bet just to see if I get any raisers, everybody folds and I'm heads up with one player. The turn comes 3d, essentially a nothing card. I check, my opponent bets, I put him on a Queen, and call, since I figured I had enough pot odds considering my King high flush draw. I river comes 10c, I've just hit a King high flush, pot odds did their job, and I'm gonna get paid. Right? I bet, my opponent raises, he's close to all in, I figure he hit a straight or a weaker flush, so I re-raise and put him all in. He calls and turns over Ac-7c for the ace high flush. Therefore pot odds are not very helpful unless you are absolutely certain you're drawing to the absolute nuts. The difference between a King high flush and an Ace high flush turned out to be about $70 in a $3-$6 game, that is he got $35 of mine, and kept $35 of his own. If he had a Queen high flush I'd have been $70 richer. | ||

| I think I screwed up a bit in my last post, river was Jack of Clubs or something, I realize it is impossible for me to both hold a card and get it on the river, but the moral of the story is my King High flush got beat by a bigger flush, which reinforces my theory that you should probably one chase an ace high flush, although I can't tell you how many times I've hit a nut flush on the turn only to have the river card pair the board and that flopped set just became either a full house or quads, bye bye money :( | ||
