Lost a tourny on ladbrokes with a very similar bad beat. Heads up 50k vs 48k, both all in 55 vs 88 after flop was 575.
The only way to beat me was to get 8 8 on the last two flops, he got it. Always did wonder about the odds, 900/1 sounds about right. Took me awhile to stop thinking about that beat. Didn't even get the bad beat bonus as it was not on a cash table
