um... no, it is some sort of a silent code but it doesn't have to be agreed on.
as for the aggressive guy raising you preflop. i would perfectly do the same thing to drive out other opponents in the hand as it increases my chance of winning the pot as i'm only heads up with the short-stack.
(is this not obvious :S?)
the biggest mistake was on your part on that hand, with a hand like 99, which is actually marginal hand considering UTG short-stack is all in, and your only in second position, and there's still tons of players after you.
either you raise it up to isolate, or you fold it.
calling is the last thing u want to do EXACTLY because of what happened, an aggressive player raising you and u not sure what to do so having to lay down the best hand, i would have done the same thing if i was in his position.
if you get called 99 is one of the worst hand to be playing as you'll be out of position, so you won't even be sure if you have the best hand when the flop comes, and there's no sidepot which makes it extra hard to decide whether to bet to chase the other person out of the hand or not.  |
