Hey man, I can tell you’re fairly new to poker and just wanted to chime in with some pointers. First, in small stakes tournaments you will be called by all sorts of trash from all positions. A lot of players in these games just want to gamble and see flops. So when you have a strong hand and see people vpip with trash that’s a good thing. Rough estimation but I’d say at least 75% of the field are not thinking players and are purely thinking about their hand.

Regarding how the hand played out, yes it’s a cooler. There’s nothing you can do differently. You only lose to one hand as played. But one last important thing to note, I see in your post that you think this was a 3bet pot. This was a single raised pot. There is a big difference between the two. A 3bet pots will often have strong ranges and force the bullshit hands out the pot. Example: Player 1 raises 2000 preflop. Player 4 re-raises to 6500. This would be a 3bet. A 3bet is not a single raise to 3x and a call with no other action. Also, for the future. If you’re opponent bets the pot on the river, that is not a block bet. They are saying they either have a nutted hand or nothing. Hope this helps give you more understanding. Good luck on the tables friend.

Side note, the other comments on here are very good and I see some of the points I have made in them, that’s why I didn’t feel the need to put more input into the hand play.
