While you think the odds pre justify calling with this hand perhaps your lack of conviction with it doesn't. You've gotta ask how you will ever make money playing it. You lead with tp and only get one caller, yet you auto put that caller on a range that beats you ie A-8. So it makes you wonder why you would lead at all. I think the all-in dynamic distracts you from villain's play because why would villain make a large bet on the end with a showdown value hand like A-8? The funny thing is that if the river was another 8 you would readily get your chips in, and yet the bigger 8 and flopped sets, which are realistically the only hands you would think beat you come the turn, still beat you come the river.
Reading this thread and thinking about it yesterday i think ur spot on.... the big bet on the end makes no sense with showdown value other than to get me off, which it did, WP sir.... its easy in retrospect, but in the heat of battle id convinced myself i was beat and i was throwing good money after bad. I must add i almost called but the oppo had bamboozled me totally ( not hard to do i admit) and i made a poor choice..but once again thanks to u guys and ur honesty i have learnt a couple of things which i will add to playbook and next time i might just get it right...
