Haha a couple tips: I play 27/21ish and have been having success at .50/1 to 2/4 lately. Basically to be a successful lag you have to know waaaay more about what is going on in the hand than your opponent. Don't turn marginal holdings into bluffs for the most part. And rarely, rarely play big pots OOP without incredibly strong holdings. This would be an incredibly long post but basically as a lag you only want to make ur big semibluffs and bluffs when an opponents range is incredibly well defined and weak. For instance in hand 1 his most likely holding is 22-77, also 99-JJ and then Ax. Against many nitty villains at .50/1 a raise on this flop with air is +ev. That being said you are probably slightly ahead of his range on this flop and his range has little to no chance of improving so call this flop. On turn you have to make a read as to whether he is overplaying a small PP or on a bluff or trying to get value from an ace. Without a read along these lines muck turn... raising the turn is complete spew as his range on turnbet contains a huge amount of Ax which is just gonna push and you will feel like an idiot and fold. Sauce.
