using small pocket pairs ONLY for set mining is a big mistake most players do. i have come to realise it because i myself was making it all the time. we see a raise and we think we can flop a set and get a big payday. thats more times than not just a dream that doesnt become a reality. if you call a raise with the intention to fold to a c-bet if you dont catch a set then you are actually losing money. lets say you are in BTN holding 44. and the CO opens for 3BB. you need to call 3BB to win a pot of 7,5BB so you are getting 1:2.5 on your money. assuming that people in the blinds are getting greater
odds after you call as well it gives you much better odds. there is also the chance of someone raising big after you so lets not take into account any action that hasnt happened yet. you will be making a set 11,8% of the time. that means that by solely using your 44 for set mining you are losing roughly 88% of the time. so your
pot odds are terrible and by applying that you are losing money in the long run. now on the other hand by making your set you can say that you have implied odds, so that is another thing to take into account. but that also means that your opponent is gonna have (or make on the flop) a big hand as well! but people open far more
hands like Aces and if they dont make their hands they obviously arent going to stack of with Q-high. if you have a read that an opponent is opening with a premium hand then calling with the sole intention of set mining is acceptable assuming this person has a stack of more than 10 times the size of the raise you need to call (e.g. if he raises from early position 5X and is a nit you can definetely call and try to get his 100BBs after flopping your set.) but the thing is that more times than not when you are facing with an open raise you are not against an overpair, but a couple of mere overcards. more times than not these holdings will miss the flop but the player holding them are gonna c-bet with them regardless. knowing your oppoents opening range is helping you understand which boards hit him and which dont. a board that didnt hit him is probably gonna be enough for you even if all the cards on the flop are bigger than your pair. a 3,7,9 flop is great for pocket 2s against an early position raise. you can definitely call the c-bet and re-evaluate on the turn. but folding after missing the flop is defintely -EV. most rainbow paired boards are also great to call c-bets with. you need to know how to play small pairs not just go for the jackpot-set or you are actually wasting your money. thats the reason why 3betting with middle pairs is profitable. because you have 1.) fold
equity against weak hands who are flipping against you 2) get the aggression so you can c-bet and take the pot if your opponents miss 3)widen your range for when you get the real goodies.
