At the risk of sounding hopelessly old-fashioned, I don't know how anyone expects to do well playing 2/1 gf is this is an opening bid. Sure, if partner fits your hand, you may make a lot of tricks with relatively few hcp, but experience, and plain probabilities, suggest that when we hold 11 black cards, partner will usually hold a lot of red cards.
We may then find ourselves forced to game...often 3N...when our only contribution will be preventing the opps from running the black suits.
Btw, 1♣ is what I call an anti-preempt. Opening a major, especially spades, with sub-minimum hands at least has the benefit of making it tougher for the opps. 1♣ makes it far easier for 2nd seat to come into the auction....by comparison, pass often operates as a preempt when LHO has an overcall but not an opening.
Are you saying there's something special about 2/1 GF which makes this unsuitable for opening, or just that you shouldn't open it playing any system with wide-range openings?
I routinely open this type of hand, and don't often come to any harm. It's partly a matter of expectation - if I open the bidding and then show some shape, partner isn't going to assume I have a 13-count. And if partner bids 3NT on a misfitting 13-count we don't have to play there. 5
♣ is playable opposite Kx AQxxx KJxxx x.
Regarding the "anti-premept" effect, I don't entirely agree. The reason it's easier for them to get in over 1
♣ is that the range of an overcall is wider than the range of an opening bid. A consequence of that is that it's harder for them to judge what level to play at. If it were easy for them to get to the right contract after 1
♣-(1
♥) showing 8+, they could get the same benefit by playing pass-(1
♥) as 8+.
