Pinching out tomatoes?

I've grown a few varieties of heritage tomatoes this year, thanks to Cinammon, and now they are growing well I'm not sure whether I should pinch out the side shoots? I have
Zapotec
Chereola
Green zebra
Cover de pigeon
Charbonneuse
Bloody butcher
Black Russian
Russian persimmon
Black seman

The chereolas are definitely looking bush type, but not sure about the others.

 

I dont know the names of those tomatoes but Monty don said if it doesn't have any obviously single stem its a bush tomato but if it has an obvious central stem then it is a cordon variety and you need to pinch out the side shoots

 

Thank you, got my first jobs for today now
And autocorrect changed Coeur to cover lol
So Coeur de pigeon- pigeon heart!

 

In general terms 'determinate' varieties are cordon type and require side-shoot removal and the 'indeterminate' varieties are bush type and don't require side-shoot removal.

You should be able to find out which types you have if you Google the varieties.
