Thanks so much for the detailed advice rpm, I really appreciate it!

H4 was a really tricky one for me. I do understand about opening sizes and how that affects how often it needs to work, I just need to refresh exactly how this is worked out mathematically. In this hand, my plan didn't extend further than c-betting the flop and I was really lost after that. After all the discussion, I agree that usually (ignoring history) 2 streets is good, and I like the bet flop/check turn/bet river line. In this case however with this particular villain I think bet/calling > check/shoving as I think his jamming range would be wider than his calling range in this spot.

Also, you're totally right about me turning hands into effective bluffs - Carrots has been telling me the same. I'll defo check out those exercises you recommended - have been on my to do list for ages, think it's about time to crack on with these!
