Redpalo: Your advice is off the mark here. You don't want to be raising super huge so you don't get any action. You want action with your premium hands, as they are the odds on favorite to win (as shown by the picture above). Yes, you will lose sometime, but every starting hand loses sometime. Why would you feel more inclined to raise AA to 15x so you don't get many players in the pot, but raise 88 or JJ to only 5x the bb or whatever so it's cheaper?? AA is less vulnerable than 88, yet you are making it almost impossible to get paid with it, but letting players stick around when you have a weaker hand.

Now don't get me wrong and think that I am suggesting you raise 88 to 15xbb or whatever and only raise AA to 2xbb. That's not the case. Your preflop raising size should be constant at almost every instance. In cash games it's generally suggested to raise any hand you think deserves a raise to 4x the big blind and add one more big blind for every limper there is (4xbb + 1bb per limper). That way players can't get any read on you and your monster hands will merge with your marginal hands so a play postflop can be less exploitable.

In a SNG It's suggested to raise around 4xbb + 1bb per limper in the early stages of the SNG and as the blinds get past say 50/100 to begin raising somewhere like 2.5xbb + 1bb per limper (reason being a 250 raise is gonna do about the same as a 3xbb raise, but save you chips). Also keep in mind in SNGs you are also fighting against the blinds, not just the players. So you want to accumulate chips when you have the chance, and there is no better opportunity to get those chips than with AA/KK preflop. So it would serve you bet not to push out all the competition by overbetting preflop.

Next you said that if you have KK and the flop comes with an Ace you back off after taking a stab. Well this has been covered in many topics on this forum, but really quickly... Let's say you have KK preflop and raise and you get 1 call. The flop comes A73r. What hands do you beat? Well you beat all but Ax, 77, 33. So if you bet what hands does he fold? Well he isn't folding 77 or 33 for sure. And he's most likely not folding any Ax that he called preflop with. So he is only folding hands that you beat. And you don't want that. So if you turn that previous statement around, he is only calling with hands that beat you (unless he calls with QQ etc, but that's probably unlikely at the micros because they hate scare cards). So instead of betting check and call a bet, because he may bluff with something you beat, but he won't call a bet unless your beat (usually).

And for what it's worth, people calling with crap like 87 isn't bad. For one if the effective stack (the least of either your stack or villians stack) is deep enough even if they know you have AA they can profitably call with 87s, and other hands you would refer to as crap. Mainly because they intend to get paid big when they hit and you can't get away from the hand. And secondly from our prespective we are till an 77%+ favorite against a hand like 87s preflop, so we aren't hurting at all. Now given you are less likely to win a huge pot when they call with 87s becaue either they hit the flop big or not, however as rilla said you need to be able to get away when your beat postflop.
