2245 is semi-balanced. 20 HCP and 4 losers.
Primes in minors should alert us to the possibility of a minor suit slam.
While 2N gets the value and approximate shape right, we can have our cake and eat it too by opening 1♣ and reversing into 2♦. Besides, if partner passes, we will be happy we didn't open 2N won't we....

Pretty bad. Just open 1♣ (I want pard to lead ♣ on opening lead) planning to rebid 2♦ to show my overall strength. This can also lay a solid predicate for a minor suit slam auction every so often.

In real life this hand will get opened 2NT fairly often - maybe 20 to 40% of the time (esp. if NV, 2NT is down only 50 a trick). I am a MUCH better dummy player than pard, 2NT can be a useful preempt, and even lum-lum pard knows the basic follow up transfer bidding sequences so we can get to our easy major suit or 3NT games.

Bad enough that you should never do it. Yes, it may sometimes gain and often won't lose, but, when it loses, it loses big...we're talking game and slam swings here, and it will lose more than it gains

You might also want to play 3N rather than 4M opposite QJxxx, Jxxxx, Jx, J, you are much more likely to play 4M if you open 2N.

The advantage of 2N is you won't hear 1♣-(2♠)-P-(3♠). Does partner have xxx, Jxxxx, xxx, xx or Axx, Jxx, xxxx, Jxx ?

IMO 2N is not hideous, but not best.

If my partner prefers being dummy than declarer I'd open 2NT. Even if they don't it is closer than people here say, Qx is good for receiving lead but still I would need stronger doubletons.

Open 1♣ is best,and then reverse bid 2♦. this hand is not suit for playing 3nt but for partner.

I would estimate 5 to 10% at most.
