Do you see any merit in my original plan of call the 3 bet and raising the turn to try fold out button who could very likely be holding an ace? Once the flop is capped, he would be getting correct odds to draw to the gut shot when I raise the turn. I posted another similar hand a while back where I did this but it was recommended that there were too many 'ifs' to attempt it. In this case we can be close to 100% sure BB will bet out if we call his 3 bet.

Another thing is that it looks like there are lots of cards that can ruin our hand (9 spades, 4 aces, four 5's) so shouldn't we wait for our equity to improve dramatically when a non dangerous turn comes and raise then?
