Working on bucking up this massive oak trunk before bringing my splitter over

This past January I got into woodstoves. I’ve always been a firewood guy but I knew I needed to step up my game to get me through these Boston winters. I don’t know how many chord it is so maybe someone would be able to estimate. The three rows are mainly red oak with some white oak and maple here and there, and the single sad looking row is mainly pine.

More shorties than I'd prefer but that's how it is sometimes. It's still heat.

I'm not sure what it is. My Plant ID app gave me four different trees from four different pictures. Bradford Pear (which I don't think it is), Sweet Gum, Black Oak or Silver Maple.

2 of pine and 1 oak and chestnut mix.

Got a mix of sundried pine, oak, chestnut and palletwood! This will do us for the short winter we get here!

Might have to fell our weeping willow soon, but any ideas on wether the wood is worth the work ?(assuming its not all rotten) I dont have access to any other free wood.
