I play cash games and buyin for 100BB - i add more if i get down to 80 BB or less, so im always deep stacked with 100BB+.
The problem you face really is; how do you build pots and get opponents to put chips in when you have a big hand?
The most common way is, ofcourse, if your opponent also makes a hand & thinks they are winning, but you can't rely on getting the best of a cooler to make money all the time.
So... slow-play... does it build pots if your opponent has a weak hand? Imo, no - it's hard to disguise check/raises as bluffs - it's a sign of great strength. You need to induce bluffs against you, and you don't do this by being a tight slow-player waiting to check raise.
If you flop a set and check - what exactly are you hoping your opponent is going to do without a hand& only 7 or 8 BB in the pot? Go all in for 90bb to win 8? At best he will c-bet 4 or 5 bb with nothing as a
bluff.
In my experience tight slow-players rarely get paid unless theres a cooler. Quite often they also let an opponent make a flush or straight then get it in bad with AA.
I often find tight players flop something strong, check it, aggresive player bets out 5 BB & then folds to the check/raise. Therefore; tight player has waited ages for a big hand, slowplayed with a check/raise, and profits a measly 8 bb or so - which could easily leave is stack again soon if he doesn't play a hand in 3 rounds.
This is why i much prefer consistent small-ball agression with a wider range (particularly in late pos), betting similar patterns with both bluffs & value bets on made hands. Overall it combines fold
equity (on my weaker holdings & bluffs) with a greater chance of getting paid when i make a stronger hand.
To give an example of a recent live hand with friends; 1 is more aggressive than me, and thus very tough to play against. The other is rigid and always slow plays. I picked up KK vs the slow player who makes standard raise, then he calls my 3 bet, so i know he's strong but not premium. The flop was very draw heavy; i think something like 9, J, Q, all same suit. He checks, i bet 50% of the pot, and he raises. I instantly fold and give him the pot of 20BB. I showed him the kings and he looked disappointed and remarked "great fold". Had this been the aggresive player i was heads-up with, we probably get all the money in given how different his table image is compared to the nit i just folded to.
As usual, the slow player gradually went broke, scaring off opponents early in pots with his obvious traps, and quickly folding to pressure when he missed flops.
