My personal notes from watching WiltonTiltâ€™s video on Poker Mathematics Episode 1.
-Poker Math is NOT a replacement for â€˜reads, tells, and our gut-feeling, or soul-readingâ€™, itâ€™s an additional tool to conquer the gameâ€¦great stuff
Iâ€™ve always thought ratios were a tad annoying.
-Wins:Loss (2:1 Favorite = Wins / (W + L) 2/(2+1)=66%. For every 2 times you win, you will lose once. 2:1 favorite.
-4:1 Dog = 1 / (1+4) 1/5=20% You will only win 20% of the time. 4:1 dog
-Variance & Hands
-High Variance: A hand with a high number of possible outcomes (a gutshot)
-Odds to memorize:
Iâ€™ll make it a point to myself to go back and memorize these.
-Rules of 2 and 4
Rule of 4 â€“ On the flop you can multiply outs by 4 and get ~% of drawing to best hand by end
Rule of 2 â€“ On the turn, you can multiply outs by 2 and get ~% of drawing to best hand
The range of hands you(or opponent) could have based on tells/betting patters/actions/etc
Try to figure out what an opponentâ€™s hand range is to do for a certain situation, and how we react with our hand range based off that situation.
-Pot Equity (Equity) and Expected Value
I had a little trouble with following along in the video. I ended up googling and finding the website http://www.blindbetpoker.com/strategy/pot-equity.html
No offense whatsoever, but as a playing unfamiliar with Pot Equity, I had trouble following at this point in the video.
Anyway, pot equity. You need to know your outs and percentage to win. For example, if you have a 55% to win (thatâ€™s called pot equity..err I think) a 10 dollar pot, thatâ€™s 5.50. If your pot equity is larger than your current action (say, call a 2 buck raise), then you should do so.
Using pot equity, we can determine the EV of a play.
Say you have a 70% chance to win 500 bucks, by calling 100 bucks. Paying 100 bucks with a pot equity of 350 (70% * 500) is clearly the move to make here.
So when to get the EV, we take the percent and amount we win, subtracted by the percent and amount we lose.
When we lose, we have a 30% to lose 100.
EV= (.7*500) â€“ (.3*100)
A positive EV play
It took me about 45 minutes to really get down the pot equity and EVâ€¦.But I think I got it. Cool. Thank you WoT for this great video.
Now the issue is, what about the times when I donâ€™t have a pencil and paper and calculator? I suppose the more I play and the more I practice, the better at this Iâ€™ll get.
