Here’s a little poker tool I made at work today. It’s no Poker Stove, but I haven’t seen something like this online yet and I got tired of doing this with pen and paper. Basically you put in different ranges and it breaks them down by hand type and shows you the percentages and hand combos of each. It doesn’t do equities or match to board (yet?). It’s mostly intended as a companion to Poker Stove to copy/paste villain ranges to see the distributions of various hand groups in their range. Here are some usage examples, it shouldn’t be difficult to figure it out:
- All hands, minus Ah,4c, plus some strong sub-ranges
- 17% of all hands, showing monster sub-range
- The KK+,AK thing
- Card removal with Axs vs SC against some 3-bet calling ranges
I don’t have a card selector like Poker Stove does, but all the fields take Poker Stove’s input just fine. Dead cards can be either individual cards or hands.
The percentages are generally not mutually-exclusive. For example, AKs will count as suited broadway, suited ace, and a suited connector (but not as a suited King). The sub-ranges are there to see what % of the villain’s range you actually fear and stuff like that.
Comment here if you spot a bug or if you think of a useful hand grouping or another feature.

i………………….don’t get it.
what question are we trying to answer?
If I had to put it in question, I guess “what constitutes a player’s range”. The classic example every beginner book shows is you put a player on AA,KK,AK and want to know how often they have pairs, Range View can do that if you enter KK+,AK as the main range and KK+ as one of the sub-ranges, and you don’t have to do the math by hand. (the math would be 12 pairs, 16 AK combos, so he has KK+ 12/28=43% of the time)
A more advanced example would be “what fraction of their range are suited-connectors”, which Range View also shows.
The question in my fourth bullet was “what’s the card removal effect of 3-betting while holding an Ace vs holding another card”, in this case assume villain’s stealing 33% of the time, and I gave 4 possible play-back ranges. The third would be a fairly nitty player, with a range of TT+,AJs+,KQs,AQo+ and folding everything else. As you can see, this calling range will constitute 17% of his range when you don’t hold an Ace, but 15% when you do hold an ace. Not a gigantic difference, but you’re getting 11% more folds which is one argument for putting Ace-rag in your 3-bet range.
Sub-ranges are intended to do stuff similar to what typical examples in Harrington on Holdem (or cash games) do, where Harrington dissects a player’s range, groups them into like hands, decides what play to make against each range, and then settles on the best option. Range View would come in handy when you’ve grouped the ranges and want to see what fraction of the overall range each group represents.
The goal is to get a better idea of what makes up a range, because I can come up with possible villain holdings, but after about 10 hands it gets pretty tough for me to see what the range really looks like. Hopefully Range View can give me a better idea of that (as in, ok 1/3 of his hands here will be drawing-type hands, or maybe realizing that in some spot the hands I actually fear only make up a tiny portion of what he holds).
When I get around to adding board analysis, this will be useful for answering questions like should you value bet the river.
This is a much more niche application than Poker Stove, and it’s mainly useful for looking at the math behind poker.
