I ran some numbers today on when to call short stack shoves after you raise and they come over the top. With a simple spreadsheet and Poker Stove these things are easy to figure out. If I still played a lot of cash no-limit Holdem, I would make a bunch of these charts so that I was prepared for any possible short stack situation. Here are the two I put together for a couple of my students.
Assuming you have made a standard raise to three times the blind, the 20 BB short stack has come over the top all-in, and no one else is involved in the hand, you should be calling a hand that has about 42% equity against his range. That gives you the following chart for that situation -
Opp Hand Range = Opp Percentage Correct Calling Range
JJ+, AK 3 % AKs, JJ+
99+, AK 4 % AKo, JJ+
99+, AQo+ 5 % AKo, TT+
88+, AJs, AQo 6 % AKo, 99+
77+, ATs, KQs, AQo 7% AQs, 99+
77+, ATs, KQs, AJo 8% AQo+, 88+
66+, ATs, KQo, AJo 9% 77+, AJs+, AQo+
44+, ATs, KQo, AJo 10% 66+, AJo+
44+, ATs, KQo, AJo 11% 66+, AJo+
If you get one caller before the short stack raises all-in for 20 BB, then you can call a little wider because of the extra money in the pot. In this spot you need to have around 39% equity against their range, and I dropped that in to a spreadsheet as well, with the following results.
Opp Hand Range = Opp Percentage Correct Calling Range
JJ+, AK 3 % AKs, JJ+
99+, AK 4 % AKo, JJ+
99+, AQo+ 5 % AQs, TT+
88+, AJs, AQo 6 % AQs, 99+
77+, ATs, KQs, AQo 7% AQo, AJs, 88+
77+, ATs, KQs, AJo 8% AQo+, AJs, 77+
66+, ATs, KQo, AJo 9% 77+, AJs+, AQo+
44+, ATs, KQo, AJo 10% 66+, AJo+
44+, ATs, KQo, AJo 11% 66+, AJo+
