It's the fish, dummy.

You can study and agonize over equity vs. your regular opponent's continuance ranges, and balance your lines vs. often-seen opponents, but much of poker simply involves hitting good hands against awful players and taking their money.

No read on my opponent except that he has a half stack. Worried about a seven obviously. Note that his small stack gives this starting hand an SPR of about 7. That's a bit in between - you can usually just bet/bet/shove overpairs and not worry about draws with overpairs and SPRs of 4/5 (the logic here is that a player starting with a drawing hand and an SPR that low has already made their mistake - they don't have the implied odds to play a draw vs. your overpair). An SPR of 7 is more dicey, though.

He's not going away. I need to bet for value and for protection. If he reraises or shoves now I probably fold my overpair (not sure if this is correct or not).

Thank you to the poker gods for what looks like worst card in the deck. There is now a 4 card straight on the board, and a spade flush (backdoor). Oh, and the board has been paired the whole time. The problem is that there's only one pot sized bet left due to the small starting stack. I feel like this commits me to the pot, so I stick it in.

All I can say about the opponent is wow. I might have played the hand just as badly, or I might not have, but from a "fundamental theorem" standpoint, I was golden and won half a buyin. +248 big blinds on the night.
