Cousin Merve, is that you?!?!?!?!?!
Lol, sorry to disappoint, but no.
By leading on the turn i might suck them both in, if i am left to check raise the player in LP i lose the BB.
If you bet 500 i think you lose them both and take the pot which in hindsight would be preferable to losing your stack.
If you do bet 150 i think you get an extra call from the bb but the utg may well not make his big semi bluff. Then you have to lay it down on the river to his all in.
Definitely in the second case but maybe not in the first you are likely to face him reraising you all in. He will believe that there is a strong chance you will fold and he is definitely nuts. I agree, it does build a big pot but then you are also busted.
