(mods, I'm not sure if this goes better in natural or non-natural - please move if you think I've misjudged)
MPs against LOLs. I'll have to explain the context, but I don't think you need any deep understanding to form judgement.
2♠ showed nominally 10-13 points, 5+♠s, with a singleton outside promised if P does only have 5. Unlike most Fantunes players, our opening bids can have both majors, more or less any normal distribution (on (65) you might prefer to pass and come in later). If 5-5 in the majors, P will be lower-end strength for his nominal range (i.e. 10-11ish).
Your relevant options, other than pass are as follows:
2N: feature ask (I include this more to preempt questions than because I anticipate anyone bidding it - the responses focus on HCP and major-suit holdings, and might leave you unable to stop below 3N if P considers himself max)
3♥: shows long Cs, forcing to 3♠
3N: to play
5♣ direct is dangerous - we haven't discussed this sequence, but P might well take it as EKCB.
What's your call?
