I would not have played this 32o ever under any condition unless I was checking in from the Big Blind. This is the lowest preflop
equity hand there is, so putting any more chips then you have to is a big mistake imo.
You played it (hopefully checking from the BB) and the flop comes up very nice for the hand. You have the Straight Flush Draw and a crappy pair. If any other diamond then the 5 comes, your pretty much done. The turn comes a 2 which gives you the weakest possible 2 pair combo available, which of course is super vunerable when the board pairs. The only cards really good for you are 3 or 5, the 2 could of made a wheel straight for A5 or 55, plus you are only good with this two pair if the board didnt pair , which is unfortunate it did, but this is the risk taken when you play the lowest cards on the deck.
