Bournemouth snatched a point in controversial fashion after referee Robert Madley reversed his decision to award the home side a last-gasp equaliser.
It didn't start well for the home side, with West Ham taking the initiative after just seven minutes, thanks to a bullet header from defender James Collins.
The hero then turned villain, by making a defensive error to allow Dan Gosling to capitalise and level the scores. It was self-destruct stuff from West Ham just before the hour mark. They completely went to sleep from a Bournemouth corner and Nathan Ake pounced in the box to stab home.
