There are those who say it's OK to ride a too-short chain as long as you never use the big/big combo which it can't loop. I disagree. Yes it's OK in a pinch, but there's always the risk that one day you'll forget which ring you're on and inadvertently shift into the taboo combination, possibly destroying the RD, rear axle, derailleur hanger or all three. The bike should be set up so that no combination leads to instant disaster.

When setting up your new chain, consider using a chain longer than the shortest possible, leaving you the option of later cutting out a damaged link, and still having enough chain.

Also take a moment to assess why you twisted a link and damaged this new chain in the first place. Odds are it was from an aggressive shift under load. These are absolutely to be avoided since they put tremendous load on the plates, either twisting them, or pushing them out on the pins leading to later breakage (always when it's least convenient). Try to anticipate your shifting needs and shift before it's too late, If you have to shift under load, lighten the pedal load to just enough to turn the crank using the bikes momentum to carry you through the shift.

Improving your riding technique will go a long way to getting the maximum service from your drive train.
