Here is the situation. You are on the left of drunk guy in a late night crazy game. Kid on right of the drunk guy is looking at drunk guy's cards. Drunk guy is very agro - bets made hands and bluffs hard - but its likely he cant tell the difference at this point anyway. That's letting kid check call as last to act having seen cards. This is a huge advantage as his relative position lets him know how everyone else on the field is going to act - the action would often be something like - check to drunk guy who pots -then it goes around and kit can then, knowing what the field has done and the drunks cards, decide the best exploit
What about if we do or dont know the drunk guy and/or kid - does that effect our actions? Does it matter if we do or don't like /respect either of them - for example what if the drunk and the kid were scumbags? Does it matter if the kid is a winner or looser? (Ie -are we ok with the kid getting a bigger stack if he is bad but we don't want that if he is good Is there an exploit we should be thinking about?
Any other considerations? Ill add spoiler later.
