Hard fork - Best position to be in if/when it forks

[Mstandish]

I'm a bit of a newb when it comes to forks. I held ethereum when it split and I'm holding btc currently.
My question is where should I hold my bit coin at the moment to best utilise the potential HF.  When I had eth it was held on poloniex,  they distubuted the new eth as a 1:1 ratio and I had a new balance of eth & ethC
However I remember this taking a long time for the exchange to distribute and that if I had held it in the ethereum wallet I would have been credited instantly. Rather then the 48 hours poloniex took.

My question is. What would be the bit coin equivalent of that, so that when it forks at block xxxxxx? I would have an instant balance of bit coin unlimited alongside my bit coin balance (assuming it follows the ethereum method) is there a wallet that will be able to hold both or if I held my btc in a wallet, how would I access my new btc unlimited balance? I don't want to get stuck waiting for poloniex to credit my allowance like last time but I don't understand enough to be able to work out how to access my bit coin unlimited on day 0.

Any advise in basic terms would be greatly appreciated.  Whats the best way for me to get bit coin unlimited as it splits?

Same thing applies, you want to hve the coins in your own wallet, not on exchange.

You can run BU node if you want.  Otherwise, you will still have the private keys which will be the same
for both chains. 

I use electrum which is SPV and I have to look into how it will know which nodes to use in the event of a split
