It sprouted in the fall foliage near the garden. I plan to transplant it.

Pointy tips is a red, those full gullets (sinuses) look like a northern red to me. A chestnut oak has many rounded tips around the edge.
Only pic I had in the gallery is the bark. Its the heaviest bark in our woods. I think the honker with the hare hole in the background is an elderly northern red.

Edit, here's a few chestnut oak leaves;

This is what I call red oak leaves. They don't look like the short pointy leaves in the opening post. I know there a lot of different varieties of red oak.

Which red oak and why you think so?
Look white oak to me.
This is a tricky one. I am reminded of something Danny taught me a few years back. Leaf shapes and bark change as a tree ages. You have a photo of a seedling and I am still leaning toward Chestnut oak. There is a European species that looks really close to this one in your photo. As Don said, it has a really really heavy bark.
The leaves in your second post are definitely white oak. If anything, they are close to Scarlet oak, which is similar with deep throats but very pointy.
I am going to (and I can't believe I am saying this) disagree with Don and say it is absolutely not a read oak. We have tons of Northern red and scarlet oak here, and that ain't it. :D But I see what he is looking at and why he thinks it's a red. However, when I do get to see a red oak seedling before a deer kills it, the leaves are miniatures of the mature tree. I get them popping up on my lawn each spring like weeds.
Transplant it and let it grow (keep the danged deer away from it) and see how the leaves develop. In a couple of years, maybe I will have to apologize to Don. ;D
This is what I call white oak - bark and leaves shown below. The leaves have rounded "fingers" whereas RO has pointed ones.

When I visited North Carolina the locals called white oak red oak. Some like to call white cedar juniper also. When you communicate outside your area this won't work. Without thinking I will still say buttonball rather than sycamore. Blame my childhood.
Chestnut oak is in the white oak group and does not have pointy tips on the leaves. Swamp chestnut oak does have points and yours may be that.
Our swamp chestnut is a member of the white oak family. Both have rounded lobes. I was always taught red / pointed and white / rounded. The oak sprouted in the original post looks like a black jack oak.
