with spr around 2 I think you have to GII on the flop.

I would just pot this texture

BTN cannot bluff raise in this pot because he has no fold equity + you block all his straight draws. vilain is obviously on a made hand

But you can never fold with those odds, maybe he is on 99, 66, 22 and you're crushed, but you can add some KK/QQ, two pairs in his range and it's right to call.

Standard bet/call on the flop, this is a good texture for us
