Bill Chen Power Ratings for Starting Hands?
Just wondered if everyone had seen this and how applicable it would be to LL Hold'em.
I originally posted this in the small stakes forum and got no comment so thought that I would try here. This was taken from RGP Thanks for your review wdbaker Denver, Co From: wchen@my-deja.com (wchen@my-deja.com) Subject: Power Ratings for Starting Hands View: Complete Thread (5 articles) Original Format Newsgroups: rec.gambling.poker Date: 1999/12/08 OK! No more rote memorization of what hands belong in which category! This idea came up after talking with Kevan Garett (sp?) at Lucky Chances about Lou Krieger's recent CP column on starting hands. The question is whether we can limit the amount of memorization needed, and maybe even give some intuition about the game. Here are four easy rules to follow which give you the "power rating" of a starting hand in a full-handed hold'em game. I came up with the rules on the fly but they do seem to work out. Of course there are refinements possible--I know A9 is better than A2--but the point is to keep it simple. RULES FOR POWER RATINGS. ------------------------------------------------------------------------ (1) HIGHEST CARD: You get these points for your highest card. A 10pts K 8 Q 7 J 6 T to 2 (face value)/2 (T = 5 pts, 9 = 4.5 pts, 8 = 4 pts, ...) (2) PAIRS: a) Double the points for the highest card. TT = 10 pts, 99 = 9 pts. b) Extra point for PRESTO! 55 = 6 pts. c) Minimum points for a pair is 5 pts (44, 33, 22). (3) SUITED: Add 2 points for suited. (4) CLOSENESS: a) Subtract 1 point for 1 gappers (AQ, J9). 2 points for 2 gappers (J8, AJ). 4 points for 3 gappers (J7, 73). 5 points for larger gappers, including A2 A3 A4 b) Extra point if you are connected or 1-gap and your highest card is lower than Q (since you then can make all higher str8's). ------------------------------------------------------------------------ --- Examples: 1) AA 2 (pair) * 10 (high card) = 20 pts. 2) AKs 10 (high card) + 2 (suited) - 0 (closeness) = 12 pts. 3) J9 6 (high card) - 1 (one gapper) + 1 (str8 bonus) = 6 pts. 4) 72s 3.5 (high card) + 2 (suited) - 5 (4 gapper) = 0.5 pts. Here's my list of "power ratings." It looks a lot like Mike Caro's, S&M, Lee Jones's, etc. The only major difference I see with S&M for the first 7 categories in a cursory glance is is that ATs is moved down a notch, and Ax actually shows up. This actually matches my intuition, for what it's worth. 20 AA 16 KK 14 QQ 12 JJ, AKs 11 AQs 10 TT, AK, AJs, KQs 9 99, AQ, KJs, QJs, JTs 8 88, AJ, ATs, KQ, KTs, QTs, J9s, T9s 7.5 98s 7 77, KJ, QJ, JT, Axs, Q9s, T8s, 87s 6.5 97s, 76s 6 66, 55, AT, KT, QT, J9, T9, K9s, J8s, 86s, 65s 5.5 98, 75s, 54s 5 44, 33, 22, Kxs, Ax, Q9, T8, 87, Q8s, T7s, 64s, 43s I only claim the hand ratings tell you which hands to play, not whether to come in for a raise nor any other aspect of how to play the hand (I mean after all it's only one parameter!) You gotta still rely on your intuition about what a raise will accomplish and whether the hand will play better multiway or with few opponents. In an unraised pot, I would play hands UTG at 8 pts, 7 for middle position, 6 in late position, and around 5.5 at the button. You should always use your poker intuition, of course. For example 54s plays well multiway so if there are a lot of callers, you should certainly play it. Similarly, AT plays well against few opponents so if nobody is in, you can come in with a raise in late-middle position even though it's a 6. Also, open raising with Ax (5 pts) on the button if everyone else folds is fine. Along the same theme, 66 is a weak hand in a 4-way pot so if there are 1 or 2 limpers who are good players, throw it away late. If there's a live button charge or only one blind, then tighten up, especially early. Finally if it's a soft game with not too much raising, or if you expect lots of callers behind you can loosen up a little especially with good multiway hands--like opening early with 7 pts or late with 5 points. To come in cold after an early raise, generally have 10 pts agianst a solid player, or 9 points against a typical player. I'll repeat the ratings don't tell you how to play the hand, but you do generally want to isolate (3-bet) with the pocket pairs you play. I think it's a good rule that each raise pushes up the requirements by at least 2 points or so. To come in cold after a re-raise, it does depends very much on the players but in most cases I'd say you have at least 12 points. In defending the BB--from my computations, I would defend with anything that shows up on the scale as 5.5 or higher but I've been told I defend too liberally. If the SB is less than 1/2 of the BB, I'd still use the guidelines for a raise, and treat it as late position if there's no raise. If the SB is 1/2 the BB or more I'd loosen the raise calling requirements by a point or so. If no raise, I'd call 1/2 the BB with anything 5 or higher and 1/3 the BB with anything, well certainly anything that's 3.5 or higher. Bill |

Re: Bill Chen Power Ratings for Starting Hands?
Looks to me like just more crap to memorize. I laughed at the no rote memorization line. How are we gonna do all the computations without memorizing his "system"? Very funny stuff. I tried to compute 10/6 suited and gave up before his chart told me if it was as good as AA or not. [img]/forums/images/icons/smile.gif[/img]

Re: Bill Chen Power Ratings for Starting Hands?
I've never seen it before - and I'm afraid I don't think it would be very useful except for the very first stages of learning the game. If this sort of thing interests you, there is already a similar points system available on the web - Hutchison system. This system seems a little easier to use - less subtraction and divison!
The same bloke also has a system for Omaha 8/B starting hands. I think this has a lot more use since the evaluation of O/8 starting hands is more complex. |

Re: Bill Chen Power Ratings for Starting Hands?
It's easier to remember hand groups, and the groups need to be specific to situation (point count would need also, and it would come to the same, but in the long run it's much easier to use memory than calculation). I rather go with the group that thinks hands have no value at all. It at least as much depends of what and how the opponents play, especially after the flop but before also.

Re: Bill Chen Power Ratings for Starting Hands?
Could you please expand on the thought that hands have no value at all. I have heard people say they just play the flop but it seems to me that you still need pre-flop rules of some sort. How do you play that way.
