Hey

I've been trying my best to learn ev caculations and im still struggling, just wondering if anyone can help me on this.

feel free to take part if u struggle in this area as well , it surely would help your game if u know when to make an ev descion. 

anyhow , I'll give you an example in jonathen little's book, if u can help me with this , i'd much apperciate it 🙂

Consider a extreme example.Assume you are in the big blind with $10,000 chips. The button , whom you know raises 100% of the time when it is folded to him, raises it to $1,500 chips at 250/500-50. The small blind folds and it is up to you. Assuming you have been fairly tight throughout the tournement so far, you should go all-in with any two cards, especially if you know your opponent will raise wide and call tight.

Here's what hapens. If your opponent calls 15 percent of the time, you will win 2,750 chips (the blinds + antes + his raise) 85 percent of the time. The remaining 15 percent of the time you will have around 35 percent chance to win a $21,000 chip pot (your $10,000+his $10,000 +blinds and antes) which gives you 7,350 when called for a 2,650 chip loss.

so you make $2,750 (0.85)-2,650(0.15)= 1,940 chips in expected profit everytime you do this.

I know how to figure out the formula , took me quite a while to understand it tbh , im just terrible at maths.

I'd like to know how jonathen came up with the answer of 2,650 chip loss? also how he figured out they had 35% chance to win? Is that how much equity they have when called? so basically any two cards has around 35% equity when called by top 15% of hands?
