Villain is a well-known, aggro Brazilian reg. Most of you will have played with him. Plays a lot of hands, some very unconventionally. Hates folding. I have a reasonable amount of history with him that I think would likely make him expect me to be pretty station-y versus him.

I think this is fairly straightforward. Don't see too much reason to do anything else here. Villain probably expects me to defend quite wide.

Again, don't think anything but check-call is really an option. My check-calling range still includes a few stronger hands, but mostly a lot of Kx and 7x. I'm not eager to check-call pairs worse than 7x very often versus this villain since he will put me in tough spots later on, but I may do it sometimes.

I decide to check-call again here. I think villain can be value-betting quite wide here (any Kx, perhaps as weak as AJ), but I also think he's likely to bet a lot of draws and gutshots - any spades, 86/65/T9/T8/98/AT/QT/AQ and maybe even a couple of others, given how wide villain's preflop range is. I decide to call and consider heroing certain rivers, but this is close to the bottom of my calling range obviously.

Here's where it gets tricky. I thought this was a spot where bluff-catching didn't look too attractive, now that his spades hit the river and some of the other draws may have shut down. However, I realised that my own range includes a lot of KsXs and 7sXs hands, so considering villain's likely tendency to value-bet quite thinly here as well as bluffing sometimes, I thought it would be a good spot to check-shove and get villain to fold any one-pair hands he was betting for thin value (probably K9+ or KT+), as well as perhaps folding some of his weaker 2-pair hands like J7 or K4, and all his bluffs obviously.

In the end villain snapped me with KJ without a moment's thought. This made it hard to avoid being results-oriented, so I figured I'd post the hand. Interested to see what you guys think.
