SB posts SB $0.05, Hero posts BB $0.10
Pre Flop: (pot: $0.15) Hero has A♥ 4♥
UTG calls $0.10, fold, CO calls $0.10, BTN raises to $0.20, SB calls $0.15, Hero calls $0.10, UTG calls $0.10, CO raises to $0.30, BTN calls $0.10, SB calls $0.10, Hero calls $0.10, UTG calls $0.10
Flop: ($1.50, 5 players) 3♠ 8♥ 3♥
SB checks, Hero checks, UTG checks, CO bets $0.10, BTN calls $0.10, fold, Hero raises to $0.20, UTG calls $0.20, CO calls $0.10, BTN calls $0.10
On the flop: 12 undiscounted outs (13 - 4 = 9 for flush and 3 (3 A) for good 2 pair);
9 discounted outs.
If A comes, it looks like that one of 4 players has A8+ and is better as me. So I schould discount 2 from 3 outs.
Against 33 or 88 I'm drawing dead. x3 can hit his x or y8 can hit his 8 for a fullhouse. I think I can discount 1 out more.
Turn: ($2.30, 4 players) T♣
Hero bets $0.20, UTG calls $0.20, CO raises to $0.33 and is all-in, BTN calls $0.33, Hero calls $0.13, UTG calls $0.13
On the turn: 12 undiscounted outs (the same as on the flop);
7 discounted outs. (I think I can discount 2 outs more.)
Against 1010 I'm drawing dead. Now z10 can hit his 10 for a fullhouse. 10 
don't help me any more - one out is gone.
River: ($3.62, 4 players) 7♥
Hero bets $0.20, fold, BTN calls $0.20
I've got 5-best nuts. I'm behind 33, 88, 1010, 77. The straight flush is not possible. If someone raises I think I would only call and don't 3bet.
Spoiler
Hero shows A♥ 4♥ (Flush, Ace High)
CO mucks K♠ T♠ (Two Pair, Tens and Threes) (Pre 33%, Flop 11%, Turn 7%)
BTN mucks 8♦ T♦ (Two Pair, Tens and Eights) (Pre 24%, Flop 45%, Turn 67%)
Hero wins $3.92
- fullhouse?
