What is the difference between soft play and collusion? is soft play just frowned upon or is this openly against the rules (cash game)
Example, you are at a casino with a person, you have no financial ties, you are not splitting profits and you have no pre plan to signify hand strength. The table is fully aware you are very much "together" and this is abundantly clear. However you have no wish to play pots against this person as to stack them would ultimately mean you would have to leave the game as you are going when they go. Therefore I assume you would be classed as soft playing as you would not play this person like you would other spots on the table.
If this situation occurs, should you just avoid playing together? Obviously whilst you may benefit from not clashing the table gets free info as clearly a 3b from A to B would be viewed joke strong and in practice it is impossible to manage 4-5 ways.
Two hand scenarios 50/50 blinds 5 handed.
Hand 1
5 handed, folded round to Player A and Player B in blinds 50/50 so SB cant fold. Player A checks Player B checks, then check down every street, Player A wins with top pair with a J kicker. What is this classed as?
Hand 2
9 handed blinds 50/50 player A makes it £6 over some limps, player B calls from BB, 5 players to flop (50/50 innit) flop comes 10 high, players B bets out £15, folded to player A flat calls with one player to act. Player folds. turn is an offsuit 2, no flush, although two card straight possible. Player B bets £15 again, player A folds. Player A exposes

which would have beaten player B with

does this look bad? what is it classed as? (note if collusion was going on, no way the hand would have been shown, Player B somewhat mystified by fold, Player A says thought you had set)
Final Question - Player A and Player B take table break together, discuss hand histories, Player B gives some coaching to player A on spots and shares information on table villains as B is a regular and A does not know villains. I do not see an issue in this off the table, am I missing something.
No issues were raised apart from raised eyebrows with AA fold but I found myself in a pretty difficult spot at points trying to ensure I remained in the rules of the game, I clearly think the above strayed out but would like to understand the boundaries, lol at me giving advice to a player to be fair, but I want to ensure in the same spot again, everything is above board.
