Hand #1

BTN: $5.00
SB: $10.15
BB: $9.99 FISH
UTG: $10.72
UTG+1: $6.92
UTG+2: $15.04
MP1: $4.97
MP2: $21.10 REGULAR PLAYER, TAG.
Hero (CO): $15.29
Pre Flop: ($0.15) Hero is CO with K
A 
4 folds, MP2 raises to $0.30, Hero raises to $1, 2 folds, BB calls $0.90, MP2 calls $0.70
i 3bet preflop for value - MP2 is playing 18/13 with 0 fold to 3bet [tho sample 2 hands]
fish who called from BB is 50/8. So his range here is wide, i guess medium PP+, braodways, Ax s. After the fish comes into a pot its no surprise the regular doesnt fold. His range is all PP, suited hands. I think he would 4bet /w KK, AA.
Flop: ($3.05) 4
K
J
(3 players)
BB checks, MP2 checks, Hero bets $1.90, BB calls $1.90, MP2 calls $1.90
I flop a TPTK, im far ahead from their ranges. So i cbet for value. I expect fish to call with his all broadway cards cos its either a pair or a straight draw. After regular calls i think he can have a strong hand like 44, JJ [KK unlikly] and also some straight draws. Raising with fish in pot probably be a bad move.
Turn: ($8.75) A
(3 players)
BB bets $7.09, MP2 raises to $18.20, Hero calls $12.39 all in
Now here the funny part. Fish shoves = easy call for me with top two, but after regular overshove call [120bb] his range becomes very nutted. He should understand that i have AK, KK, AA here alot. I wouldnt cbet flop without a hand vs two callers and one fish.
River: ($40.62) T
(3 players - 1 is all in)

On this flop im not sure about raising, i choose to call all streets. And if he checks just bet turn/river.

Raise here is waaaay too thin. The only hand i can expect him to call and loose vs me is AQ. Thats makes 9 combos. 66, QQ, AA, TT, some KJ make a alot more combos..
With his betsizing its a call, and if he would be smth like 6$+ i should probably even fold, agree?

A 
3 folds, MP1 raises to $0.30, 1 fold, Hero raises to $1, 3 folds, MP1 calls $0.70
12/10 tight guy, folds to 3bets alot (82%) his range for calling is 88-QQ. AK, maybe AQs.
Flop: ($2.15) 9
Q
2
(2 players)
MP1 checks, Hero checks
I decided ill go for two streets of value.
Turn: ($2.15) 6
(2 players)
MP1 bets $1.20, Hero calls $1.20
I put him on TT-JJ here alot, AQ, and hand like AKhh.
River: ($4.55) 6
(2 players)
MP1 checks, Hero bets $3.00, MP1 raises to $8.73, Hero calls $5.73
as planned making an value bet, with intention to get called by AQ most everytime, and maybe TT-JJ. Though he surprised me and made a shove which i guess is never a bluff and his range now goes to hands like 99, QQ, AKhh, AQhh.

SPEW TIME. Well preflop is somewhat OK. I dont do that alot, but the player was TAG 16/14 with 13% of 3bet from SB vs steal. [2/15] So i made a 4bet given with the dynamics of zoom which would look exstremely strong and ppl fold things like AK, JJ to it. I should probably take a hand with a blocker to 4bet bluff next time or atleast suited hand for extra equity.
Flop: ($5.50) K
9
T
(2 players)
SB checks, Hero bets $4.00, SB raises to $9.50, Hero calls $4.17 all in
Like i said my range looks fkn strong so his calls means he have also a strong hand. But i made OESD and hoped he had QQ lolz. The best play is just to shutdown, because we dont have so much fold equity in 4bet pot.
Turn: ($21.84) 5

J 
3 folds, MP1 raises to $0.30, 1 fold, Hero calls $0.30, BTN calls $0.30, 2 folds
9/7 guy opens pre. Probably calling is not so good here because he doesnt have worse aces in his range.
Flop: ($1.05) 8

flopped tptk, easy call.
Turn: ($2.55) J
(2 players)
MP1 checks, Hero bets $1.20, MP1 raises to $3.81, Hero calls $2.61
Now the tricky part. He checks to me after J came. I decided i will make a small value to get him to the river with a hand like QQ. But he raises. That can be a bluff, or maybe some stupid 'looking for information with my AA raise' or a strong hand like set and maybe worse trips. I decided to call.
River: ($10.17) 9
(2 players)
MP1 bets $6.00, Hero calls $5.72 all in
River he puts me on AI. So basically its a worse trips or fullhouse. With the posabillity of fullhouse a slight bigger. Its hard to fold trips with top kicker. So i guess its just a bad luck.

im facing a dont bet from 11/8 nitty guy. I dont have any information about his donk betting range. So i can mean alot of hands - air, draws, sets. Decided to call.
Turn: ($1.70) 4
(2 players)
SB checks, Hero checks
Turn he checks. If he have air - im ahead. And i dont think i can fold a hand like 88 if its in his range so i check behind.
River: ($1.70) 3
(2 players)
SB bets $1.50, Hero raises to $3.50, SB raises to $11.41, Hero calls $5.70 all in
I rivered nut flush. He bets out and i put him on air trying to win hands, worse flushes, but also he can have monster hands = fullhouses.
I decided to make a thin raise to get called by worse flushes mb two pairs. I dont think he pushes with worse so i should have folded.
