View Full Version : SNGPT and KS hand range %s
I was fooling around with SNGPT and, for one of my problems, got a calling range of:
22+,A2+,K9o+,K5s+,QTo+,Q9s+,JTo,J8s+,T7s+,97s+,86s +,76s,65s (34%)
This struck me as odd -- I wouldn't have guessed K8o was worse than 65s. I looked them up on the KS list and found K8o at #55 and 65s at #126.
So, I entered a range of 34% and had SNGPT convert it, getting:
22+,A2+,K5o+,K2s+,QTo+,Q8s+,J9s+.
I had always suspected that an ideal pushing range of 30% (or whatever) didn't always correspond to the top 30% of KS ranked hands. But, I had never noticed a case like this (never looked real hard). And, I have never seen it discussed. So, I thought I'd point it out. I don't know if it has any practical consequences.

Yeah it does, and I've often thought about it myself, the problem is how do you get a definitive list of pushing hands. It's very open to subjective opinions and everyone's may well even be different. So we use the KS one as it's a good basic one which "covers all bases". Plus which it is actually the range you should use (in theory) for SB pushes into a BB, because it's been proven by maths to be that way.
I'd guess it's because of hands that will be dominated if called.

pretty much thats how it works. if you were to derive a list based on which hand does best against any 2, that would be quite a bit different, as the opponent wont be calling with any two, only a selected list of hands. therefore, you must modify your push hands. holla

You know the problem that the KS numbers come from? They have to do with how much you can push and have +EV (HU only not necessarily tourney - no ICM) IF you show your cards AND your opponent plays perfectly with that info.
Yes, I know how the KS ranking was generated. So, as I said in my original post, I had always suspected there were differences between top x% for pushing/calling purpsoes and top x% of KS rankings.
But, I was surprised at the extreme case where KS ranked #126 was included in a range and KS ranked #55 was excluded.

ok, np. A lot of people don't get the KS numbers.

The middle suited connectors are relatively strong against a very strong range, and relatively weak against a broad range.
This may seem confusing at first. Take a simple example:
76s vs AA,KK,QQ 22% (very strong range)
76s vs A2+,K2+,Q2+,22+ 40% (broad range)
KJo vs AA,KK,QQ 18%
KJo vs A2+,K2+,Q2+,22+ 51%
KJo is better against a broader range. 76s is better against a tight range.
76s is not ahead against much but has a reasonable chance to beat even very strong hands with straights or flushes. KJo is ahead a lot of hands to start, but is dominated by a lot of strong hands.
The nature of the KS method is that it ranks strong hands against strong ranges and mid-hands against broad ranges. This is appropriate in many cases but masks some more subtle effects like the strength of a middle suited connector against a strong range.
IMO this just goes to show that any particular ranking is really a limited view of the preflop hands. Their strength is always relative to a situation, and any attempt at a "universal" ranking is going to miss something.
IMO this is important to understand and has practical significance.
