ISF needs to:

1. Preflop: Cold call less since villain looks to be very hard to exploit in raised pots ip.

2. 3bet pots: Stop floating or raising cbets on flop because villain is playing fit or fold once he 3bets. Whether or not to shove on turn depends on how often villain folds to cbets since if he doesn't much then his floating range is very wide due to high % of calling pf 3bets.

3. Raised pots: Stop floating villain's c/r in raised pots due to rarity and probable strength. Fire more triple barrels because villain's multi-street felting range is polarized, and tripling should get him off draws (duh) and marginal pairs by the river. Don't single-street bluff fourth or fifth because villain won't fold a made hand.

Villain needs to:

1. Preflop: Play more like ISF.

2. 3bet pots: Shove more turns after ISF cbets flop then checks turn since ISF's felting range then becomes tiny.

3. Raised pots: C/c less and c/r more since this will allow him to bluff better/more. Double more since ISF doesn't know what he's doing when playing passively oop.
