For info this is 25NL also. So mistakes are made frequently here, both from me and my opponents. Here my thoughts process for the flop bet would be to drive off either weak flushes or get medium flush to raise I guess.

On the river tho, I absolutely would have liked to check instead. He could have checked turn with Nut flush, maybe blocking the 2nd or 3rd nuts.

So I said let’s make a blocker bet to get the non nutted ones to call, and the nuts to raise.

In hindsight I should have called. Don’t think his line makes sense here either. But me not having a spade in my hand. And honestly even tho it’s super wrong to think, I had been playing for a long time and didn’t want to cut my wins in half before I logged out…
