Hand 1 - i mean you have the second nuts so it's not horrible. I do agree though that given this particular board, and the spades that the board blocks and that you block, the only other flushes he can now have that we beat are Q7ss (unlikely UTG), 67ss, 56ss, 45ss. So yah it's closer than my first instinct, but I still don't think ppl can find a fold with KKK/AAA here so I'd probably still jam.

Hand 2 - You aren't getting any folds on this flop. So many hands are coordinated with GS/OESD etc. Firing one seems ok I suppose, but you gotta be done with it after that. If you're bluffing on this board with this hand, you're going to end up with WAYY too many bluffs here.

Hand 3 - I would just bet bet bet, but after you c/c I like the line.

Hand 4 - This is one of those hands that convinced me a long time ago that you can just fold a ton of 3b and then 4b when you have it and ppl will still pay you off because they think "he must be fed up finally". That being said I think TT is fine as a 3b/5b hand overall. If you were jamming a low pair cause he must be sick of you, then I'd say you're reaching too far.

Hand 5 - Haha see above. Reaching too far in this hand. If they fold once and 4b you the next time, I think that could be a bluff and they are taking a quick stand. If they fold 3 times ina row or 4, and 4b you, they are probably just waiting for something.

What is your 3b %?
