At first I thought this was an easy fold but now that I look at it i am wondering if I made correct play. UTG Open-Raises preflop then check-raises CO's 1/3 pot size bet with an ALL-IN what would he do this with? because the board was wet was a micro player and thought someone else would bet for him with many players and he wanted to get a bit more money in the pot by check raising instead of leading out .

I put him on a range of AA-TT,AJs+,77,44,33, AKo,


MY HAND- FLUSHDRAW +GUTSHOT = 12 outs 12x4=48%

LOSING TO- AJs+(hearts)=#3 combos
77,44,33 have outs to hit full house if I hit flush on turn

basically beating the rest if a heart comes, as long as its not runner runner hearts and they contain pocket pair with a higher heart.

am I right here or should there be card removal for that even though there is a wide combination of possible cards to come with 2 streets left? do we discount the A,K,Q,J of hearts for his pocket pairs? should there be card removal for possible full houses aswell and how would i calculate that without using an equity calculator?

anyways I used the calculator for my equity against the range I put him on and it is 50.73% for him while im getting 49.27%

Equity Final Call Formula :

Price of calling/ (pot size+price of calling)=44% Required Equity


pot was $0.25 beginning of flop,MP bets $0.08, I called $0.08, UTG all in 2$

price of calling= $2-$0.08=$1.92

pot size+price of calling=$4.33

$1.92/$4.33=0.443

Our Equity was 49.27% should we have called or did i am i making calculation mistakes any help plz
