Sit and go funk plus some strategy stuff

I have kind of lost my way with sit and go tournaments and strayed from the path of concentrating on them to build my bankroll/improve my play. I am a recreational player and I do not always have time to set aside 1.5 hours to play a full ring game.  I have been dabbling with limit cash, to try and improve my post flop hand reading skills, but that seems like a waste of time at the lower limits, since players are apt to play most hands, bluff frequently and overvalue the hands that they do make.  I am basically in a bit of a funk with nano stakes online poker so I have tried slightly higher stakes cash to get the buzz back.  Even though I am only rolled for the lowest limits the money has stopped meaning something to me and I am missing the live action since our home games have been on hold. I have also become isanely weak passive at certain points in tournaments, and sometimes in cash games, especially when facing players who never fold. If I limp another ace shorthanded I will have to resign my post as a tight-agressive Dan Harrington-wannabe!

Strategy bit:
On a more positive note I have made 2 important poker discoveries lately: the first is that cash game players who min bet flop and turn usually have missed overcards (even if they limped in) or a small pocket pair that missed the board. They will often call a reraise with all of these hands so you can raise for value with just about any made hand and best or bear best overcards, on any street.  If they bet heavy on the end you can fold anything below two pair, as this is never a bluff online. They are esentially betting the strength of their hand allowing you to play perfectly. I spotted a player who was doing this today, who was betting 2x (his version of the min bet) at any checked flop so I check raised AKo for value IP on a ragged low flop. This move bought me a freecard on the turn, then I spiked an ace on the end and was able to bet for value as he held on and called with his 3rd pair or whatever.

My second discovery is that in a sit and go if you have 30bb+ the optimal raise size is between 3 and 3.5BB to gain maximum value without offering the blinds too favourable pot odds or betting a silly mount that dimishes your stack. In other words any less is too easy for the blinds to call and mess with you, any more is costing you too much if you are correctly widening your range to blind steal at this point in the game. At $25/50 level this would be around $162. It has the added value of being a confusing amount, and when people are confused they make bad decisions;)
