Anyone else do this?

Yes you are right, not everyone is paying attention, especially, the multitablers aren't.

I sense it works out now and then. But on reflection I don't think it makes a big difference.

Really the important thing is to recognise the moments when its pointless making "a continuation bet" hoping everyone folds.

And I think thats when there is strong co-ordination between the 3 flop cards and none of it helps you. 3 overcards, 3 flush cards, etc

Although against 1 caller who limped, making this bet every time is probably right.
