Once i'd called to see a flop and missed ..

i'd have passed to any bet..
What were you calling to hit with 87 ...

Not , K 8 4 ..turn Q
to call or raise Pre-Flop with 87 your looking to hit a mystery straight or a miracle full house ....when you've hit an 8 on the river ...it's a gamble .. you haven't a clue where you are..............but then again it's Ladbrokes so, as i said,
I dont know
