Are these FG 2 Clubs openings?

In Romex, the first two qualify for a 1NT opening (4-5 losers, 18-21 HCP, 6+ controls), the other two would be opened at the one level.

Some interesting differences of opinion.

For the first 2 hands I can't envisage making game if partner passed a 1 open, so as that is my definition of a 2♣ bid then these open 1♥. Any seat or vulnerability. You must have a GF continuation, though (I start with Gazzilli and if partner just signs off, bid game).

 

The third I would open 2♣ to avoid missing game, and all I want to know is whether partner has any tricks for the slam, so 2♣ is perfect. I would also open 2♣ if the ♠J was the 3.

 

The last hand would have me going into a trance for a while. I don't like 2♣ because I don't want to force to the 4 level, I don't like a gambling 3NT because partner will undoubtedly bid 4♣, so I will open 1♣, and see where it goes.

1st and 2nd hand: 1♥ unless you play 2♣ as GF or a semiforcing in a major.

 

3rd hand: This I would open 2♣. I have game in my hand.

 

4th hand: Okay 4♣ is no game but 9.5 tricks is too much for 1♣ so I open two.

First hand is clear cut case, second one...ok depends on style; i would open 2C but then again thats me:). Fourth one is obviously not u lack both tricks and strength. Thrid one is not 2C opening; why not? because u hand lacks defence. U have 2 outside aces, what do u do when prd dbls 5H bid advocating weak hand and warning u not to bid anymore.?

Third hand is 1C opening and fourth hand is textbook namyats some sort.
