I'm still trying to judge that perfect balance point between keeping people p(l)aying and not getting outdrawn.

I'd have probably played it as you did but maybe as was suggested above a little more aggro on the flop due to the flush possibility.

If I hit a set on the flop I'm praying it's rainbow and no connectors! Don't want much really...

If either of those does appear I tend to bet big and try to take it down there - that may well be a result of playing at a level where people will call too much with too little right now though.

Nice pot btw
