So here's a little situation that happened last night, and I am not quite sure if I should have played it differently or if I just got unlucky.  I am at the final table with 8 players left.  Blinds are 200/400, big blind is forced all in for 400 chips.  Second to act who is maybe 3rd in chips and big stack sitting 3 behind the dealer who has about double our stacks limp into the pot, and I have A5 off in the small blind so I follow.  (i am sitting on about 1800 in chips (about 4th stack).  I check blind indicating my good will to check it down unless I hit a monster and to have the best shot of knocking out short stack.  Flop comes down Ace diamonds, Jack diamonds, 7 clubs.  First guy also checks and the big stack throws out 800.  I push all in for 1400, smelling a diamond draw.  First guy thinks for a while and states "I can't believe I am laying this down"and folds,  Big stack calls.  I ask, "Are you on a draw?"  He states, "yeah, so?"  Well, he flips over the Q diamonds and 10 hearts (gut shot straight draw if you aren't following too closely here).  Running diamonds hit the board giving him the Q high flush, all-in player has the 10 high flush.  I keep running through this saying to myself I would never bet into a dry side pot without significantly improving my hand, and best case scenario I go all in first and the big stack may fold and I keep the other short stack in also.  Would love to hear how others might have handled this situation differently.
