I fold pre, 2nd hand in i cant see any need in gettin involved. Your Q on value, defo lead the turn again with a weak bet like 260-300. Many players are not going to put you on 8x esp 8dxd, your so huge! The c/r obv is pretty see through, where as u lead, they maybe rep the 8 themselves.
Hand 2
You could maybe only call this a cooler if your all-in pre AKcc V's QQ, pretty standered race. You've committed 25% of your stack pre but sometimes you just got to let it go, c/f for me im afraid.
