Your hand:
Sp 5,3,2
H A,6
D K,10,8,5,4,3
Cl Q,4
Vuln. against not would you open first place? Would you open (if 2 Dia is multi) 3 Dia?
How would you qualify the player who opens this hand 3 Diamond first place vuln.? Novice, beginner, intermediate, advanced or expert?
I need your opinion! Thanks

Hi... if you want an accurate opinion, you really will have to provide more information. Is this imps or matchpoints? Does the person holding these cards need to create a swing (say late in MP event where he needs to huge swings to win, or in an imp barometer imp game and his side is well behind with just a board or two remaining and he knows it?). Sometimes, an expert, who is place into despirate situation will make a despirate bid. If something unexpected happens as a result, he can gain a good result. If he gets clobbered, well, he was going to lose anyway.
Having said that, let's assume this is the second board of a long IMP match with a flat first board, and the person holding these cards bids 3Diamonds vulnerable in first seat. I would say this person is either totally reckless expert who has absolutely no respect for his opponents and is knowingly making a horrible bid, or a complete novice who sees a long suit and less than an opening hand an opens in it.
This hand
a) lacks a good quality suit

has slow winners in side suit (club Q)
c) a side quick trick (heart ACE)
3D vul is not the worse bid ever, but clearly it is not the right bid (as long as the person making the bid is not intentionally trying to create a swing one way or the other in the despirate situations I mentioned earlier). BTW. the ability to know when the risk/reward for the non-standard bid favors making the off the wall bid as it relates to the overall event not the hand in question is a mark of a real expert. If they will lose anyway without doing something odd, makes them very dangerous opponents late in an event.
