# EV Calculations - Math Check

Just finished the Core module on Math1 and played a few hands tonight with a view to doing some simple EV cals to check i've got the math down.

Please check these calculations. (Apologies for lack of hand converter).

Hand 1:

0.02/0.05NL

I open raise KQo in MP3 to 0.20. Folds to BB who 3 bets to 0.75. SB Folds. Pot is 0.97.

So it's 0.55 for me to call giving me 1.75:1 Pot odds against a 3 bet range which i figure leaves me a 40% chance against his range.

EV: (0.4 x 0.97) - (0.6 x 0.55)

= 0.058

Positive EV.

If i reduce my odds to 20%

EV: (0.2 x 0.97) - (0.8 x 0.55)

= -0.246

Negative EV

Hand 2:

0.02/0.05NL

I open raise 77 in MP1 to 0.15. Folds to SB who 3 bets to 0.50. BB Folds. Pot is 0.72.

So it's 0.35 for me to call giving me 2:1 Pot odds against a 3 bet range which i figure leaves me a 25% chance against his range.

EV: (0.25 x 0.72) - (0.75 x 0.35)

= -0.0825

Negative EV.

Thanks.

3,654-What's the origin of these "% chances" that you provide?

64✭✭I have very few hands played against either villain so i'm I'm assuming a 3 bet range is 10+, KQ+.

Should I put them on a wider range and thereby giving myself better odds of winning?

Thanks.

3,654-Gotcha. Okay ranging them is excellent, but calculating EV here doesn't really tell you anything.

Let's take the 77 hand. Suppose you're playing live against a nit whose 3-bet range is literally AA. Your

equityis about 20%, but your EV on a call might be massively positive.64✭✭calculating EV here doesn't really tell you anything.

Why not?

Thanks.

3,654-20% equity is true for all underpairs against overpairs preflop. And yes, provided you're deep enough, implied odds allow you to call here as a notional massive underdog.

64✭✭Correct. I'm totally just focusing on pre flop EV calcs. I just want to make sure i understand the math.

I'm ignoring the fact that it's a multi street game just for these 3 EV calc exercises.

So that said. Are my 3 EV Calculations correct (assuming my equity is correct for each hand)?

Thanks
