I can"t see how you do anything other than stack off here.
the stacks are big here so I think flatting pre is ok but given the way villain plays the hand (very well IMO) it is still difficult not to lose 300BB here
+1, set over set is really unlucky :"( set over set versus the only other 300bb stack :"( :"( :"( :"( have you been skipping church??
Hate the 3b pre, what do you think 3b"ing achieves?
How you deal with the aftermath can be the difference though, you can look for solace and there is plenty to be had in this instance, or, you can eek out the smallest amount of clues that
may just get you to a position where you eventually recognise that folding is a real consideration.
As an aside, it seems to me that you are a little hard on yourself when it comes to your cash game. I read earlier in the blog that you are running at 5bb/100 hands, that would put you in the top 5% bracket afaik. Imho it is important to acknowledge that, it can feed your enthusiasm for the game.
