Part of my current viewpoint on poker is that understanding the betting decisions is key. Being good at putting your opponents on ranges is fairly useless if you can't make the right decision based on that decision. Here are a few exercises where I'll give you Villain's range in a situation and you decide what you think the best line is.

I've decided to make all of these exercises have to do with short-stacks since that's always a fun topic.

You will get the most out of these exercises if you complete them in three steps. The first step is to work out what you think the right play is without any tools or writing anything down. The second step is to work it out on pen/paper using whatever tools you deem necessary and try to figure out if the decision you came to in the first step was correct or not. The last step is to post all of your findings for each exercise here and let myself and others comment on your analysis.

Exercise 1: Preflop, it folds to the small blind who had 15bb before he posted the blind and you have him covered. He open shoves {22+, K2+, A2+, QT+, JT}. What hands can you call with profitably in the big blind?

Exercise 2: Preflop, a 20bb stack opens for 5x with {AQ+, 99+} UTG. You call on the button with A K and you have him covered. The flop pot is 11bb after the rake and you have 15bb behind. The flop comes AQTr. Villain open shoves 100% of his range. Can you call profitably?

Exercise 3: Preflop, it folds to you on the button. Both blinds had 20bb stacks before posting the blinds and you have them covered. You open raise to 4x, the SB shoves {AT+, 22+}, then the BB shoves {AQ+, 88}. What is your profitable calling range?

I look forward to your answers.
