Season crabs with salt and pepper and dredge in the flour, shaking off excess. Set aside.
In a large skillet over medium high heat, add the oil and saute the crabs until soft, about 2 minutes on each side. Remove the crabs and set aside. Add the garlic and cook for 1 minute. Then add the capers and white wine. Cook until wine has reduced to about 1/2. Swirl in the butter and the chopped chives. Season with salt and pepper.
Transfer crabs to a plate, spoon sauce over the crabs.
