Pardon me if it seems like I’m bragging–it’s just that I had pretty given up on ALL IN Expert so it’s really a pleasure to finally see it being discussed.
Another cool program I just recently found is called All-in-Expert. Its kind of similar to pokerstove in that it deals with ranges but its just for preflop play. You put in the amount in the current pot, the amount you have to call all-in and define your opponents range, and the software pumps out a grid of all possible hands and tells you whether you should fold or go all in with each hand and it gives you your ROI against your viillains range.
This tool has helped me a lot in dealing with those super tight shortstack players that only play premium hands. I was raising them all-in with hands like AK and JJ which was actually a mistake. The only hands I could profitably raise them with were QQ+. Even when I raised first in to 3xbb and they pushed all in for 20bb I found that calling with AK was a mistake. The better your pot odds get, the more hands you can profitably add into your calling range.
