The whole point of playing sc's is getting to see a flop cheap and hoping to stack some donkey who overplays his top pair. If you have to put in 15% of your stack just to see the flop then you are not nearly going to stack the guy enough times to make it profitable. Obv in rebuy tournies when stacks are much deeper then sometimes you can call a larger raise if you know the villan to be a major donk, but I usually just try to get in cheap, that way I can get out cheap if I miss.

In the early levels I would call with suited connectors in position against a donk as long as it didnt cost me more than about 5% of my stack.

In the mid-late stages suited connectors are stealing and restealing hands for me in position. You shouldnt just call with them...unless somebody miniraises and you're in the BB. Even if you and a raiser are deep enough to where a call might be worth it, i would always be aggressive and reraise in position. Obv this is against a MP raiser. Against an EP raiser whos really deep i would probably call and see the flop.

Donk, i dont like the idea of restealing with just any hand. You need to do it with something playable at least...just not K2, J3 etc.
