Was I right to re-raise pot?

[jj_frap]

Sorry about the format, but Bison was giving me garbage output when I tried getting this hand converted.

I flopped top set with a non-nut flush draw + a redraw to boat/qauds. The game has been loose and passive, and I figure I'm facing either a nut flush draw (which likely won't hit because I have two small diamonds) or people overvaluing a hand like two-pair or bottom set.

You got the money in when it was good. You shouldn't need to ask questions like this, put the hands into two dimes and look for which one was favourite. If that was you , then you were correct to reraise. On this flop, I would be pissed off if I hadn't gotten all my chips in. Sure people play wraps and flush draws, but A456 at an omaha table? seems rare to be an underdog on this flop.

Wow.

At this level shove, shove, shove with top set if there are no possible straights or flushes at the moment. It's rare that you are a dog heads up, especially on this board and in a multiway pot you always have a ton of equity
