How to loosen up your shove/calling range in heads up hyper and super turbosFar too many players are not calling shoves anywhere near as wide as they should when they're short stacked and even more so after they have raised pre flop in the first place. Rather that tell you what to raise and then call shoves with, I'm going to teach you how to work it out yourself, and you'll probably be surprised at some of the results.
Step One - Pot OddsThe first thing that we need to think about are our pot odds. What pot odds do we need to call our opponents shove and how do we work that out? A really simple math exercise is this one: 1) How much is it going to cost us to call? 2) Take the answer to question 1 and divide it by the total amount of chips that we can win if we call. 3) Multiply that number by 100.
Here is an exampleLet's say that we have effective stacks of 12bb (effective stacks meaning that's all we can win or lose in any one hand, or the shortest stack) and we min raise from the button. Our opponent then decides to shove on us. Now let's do the math. It will cost us 10bb to call. So that's 10/24 (24 being the total that we can win) which = 0.416. We take 0.416 and multiply it by 100 and that gives us 41.6, which is the equity that we need to call the shove.
Step Two - Working out the equity that our hand has vs his shoving rangeSo here we need to guestimate a reasonable shoving range for our opponents. Obviously this can vary from player to player but I think this is reasonable for a tightish but aggressive player.
Step Three - Our HandThis is the part that you should be working out over and over again. You'll often be caught in a game where you raise and get shoved on and you won't know what to do. These are the hands that you should then make a note of before crunching the numbers. The more you repeat this process, the more instinctual your understanding of ranges and equity will become and the sharper/ more accurate your decisions will become.
Example handsLets give ourselves a variety of hands to try and get a handle on our equity. I'm going to use some free poker software called 'Poker Stove' to help us with our equity calculations bellow.
1. K6 off suit - 41.138% Equity (so it's a fold)
2. T9 off suit - 39.28% Equity (snap fold)
3. T9 suited - 42.489% equity, and it's a call.
