You're playing a swiss, opponents are not experts if that matters to you. You also play intermediate jump overcalls so your 1♥ could be on a weak 2.
First of all, do you X or pass? 2ndly, how do you expect partner to react to each of these bids. How often would you expect partner to pull a X? How often would you expect him to bid 5♥ if you pass?
