Cheers for replies guys, seems mixed, so I guess the jury's still out.

On reflection, the turn was horrible, 4:1 pot odds and 11 outs (9 spades and two Jacks) so I folded with 20% pot odds and ~22% equity. Oh noes. It's a clear-cut call before we even consider implied odds, which are very significant here.

Ah well, I'll know next time.

1, your preflop raise. What were you really trying to do? Keep him in the pot or make him fold his hand? If it were to make him fold his hand I think that your reraise was just not big enough.
I thought I was ahead so I popped it up. I don't hate him folding and I don't hate seeing a flop. Is this a leak?
