Pre-Flop: ($0.08, 6 players) justkyle88 is UTG+1 6♣ 6♦
1 fold, justkyle88 raises to $0.15, 3 folds, BB calls $0.10

Standard

Flop: 7♠ 4♥ 7♦ ($0.33, 2 players)
BB bets $0.20, justkyle88 calls $0.20

When he donks on this board and sizing I feel it could be a random 4x, 55, sometimes a 7 bunch of broadways where he's donking because my raising range doesn't hit that board.
Never folding, So I decided to call because I thought raising was going to be a tough decision if he shoved me.

Turn: 9♠ ($0.73, 2 players)
BB bets $0.40, justkyle88 calls $0.40

Not totally happy with him betting again but I'd say majority of his range still consists of broadways trying to push me off my hand.

River: A♥ ($1.53, 2 players)
BB bets $3.25, justkyle88 calls $3.25

At the time I was on rage tilt when he shoved and made a crying call.
I kept saying to myself the only hand that made sense was A4 by the river.
