New block, 1 year old chain..

Is this a match made in hell or will I get away with it? The block is on and I don't have a new chain, I feel like such a rebel, who wants to be in my gang!
Classic Al, I may see you tomorrow lunchtime for one of your finest, cheapest SRAM chains...
Get yerself one o those park tools chain measure tools and if chain measures within wear range its ok with new block.By replacing chains regular it stops wear on block and middle ring .I normally use 3 chains to one block and front ring and never break a chain.
Come to think of it this chain is not that old, maybe 5 months, I'm going to put on my finest cod piece and lamp out of it tonight.
