I agree with you, so why are you balancing on this hand with horrible shape? Your partner is known to have 4-5 hearts and 2-3 spades. They may or may not have a fit and we will often not have a fit. It's not like we have a shapely monster we are 3244. We also have excellent defensive values and pretty bad offensive values. On top of that even with a 4-4 fit we are pretty likely to get a 4-1 break
Because my instinct tells me opps are going to make this. Maybe holding them to 8 tricks will be a good MP score, but my experience is it's won't. Agree I can easily be wrong in practice, but I won't fight my instincts and so, at these colours, think I'll give it one last try to keep destiny in my own hands.
Final note: obviously, wouldn't even dream to do if 2♠ only guarantees 4 cards. Nor vulnerable. At teams the profit for grabs is probably also too small for the risk.
