Hi guys,

This is my first time posting on this forum. I've got a hand that represents a lot of my hands where I spew away chips and hopefully I'll be able to understand what I can work on and theory I can practice.

BTN: 200.6 BB vpip: 18, pfr, 7, 3b: 0, F3B: 50 ~27 hands
Hero (SB): 162.8 BB
BB: 123.4 BB
UTG: 84.8 BB
MP: 346.4 BB vpip: 64, pfr, 40, 3b: 11, F3B: 0 ~27 hands
CO: 84.1 BB

Hero posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has Ad Ah
fold, MP raises to 3.7 BB, fold, BTN calls 3.7 BB, Hero raises to 16 BB, fold, MP calls 12.3 BB, BTN calls 12.3 BB

Flop : (49 BB, 3 players) 3h 3d 7c
Hero checks, MP bets 32.8 BB, BTN calls 32.8 BB, Hero calls 32.8 BB

My thought process here was that there aren't many 3's in their calling range aside from A3s which I block. MP will be betting VERY wide here as his stats will look a lot like a maniac and BU will be calling with any overpair or possible hands like AQs or AKs with a BDFD which should've 4bet anyway. My only concern is 77 which the BU may be cold calling when faced with decent pot odds to set mine.

Turn : (147.4 BB, 3 players) 4c
Hero checks, MP checks, BTN checks

Turn looks like a solid brick and MP bets out with his extremely wide range again. I never really thought about raising here because I wanted to keep the maniac in. It appears that BU's range is heavily weighted towards overpairs and (possibly sets -- what're your thoughts?)

River : (147.4 BB, 3 players) Qc
Hero checks, MP bets 72.2 BB, BTN raises to 151.8 BB and is all-in, Hero calls 114 BB and is all-in, fold

I find this a very strange play. BU can't have KK and QQ because maybe he would 4bet it preflop or try to get it in. I'm leaning towards 77 or 44 here because 99-JJ might only want to flat. This is where I'm concerned. When we're playing this deep I tend to forget how much tighter I should be calling off a shove. This is the spot where I spew a ton of chips because of my strong holdings. It's like I know in my gut I'm beat but I still call the shove anyway.

BTN shows 3s 3c (Four of a Kind, Threes)
(Pre 19%, Flop 99.9%, Turn 100%)

Hero shows Ad Ah (Two Pair, Aces and Threes)
(Pre 81%, Flop 0.1%, Turn 0%)

BTN wins 425.3 BB

Let me know your thoughts on how I can improve. I don't normally post but I guess downswings make you do things out of the ordinary lol. Thanks in advance
