6Max SnG Bubble/HU strategy -- deep stacks
I hope you can help me out a little hear. I've been playing a lot of 6Max SnGs lately and I'm having quite a bit or trouble on the bubble and subsequently heads up. In the format I am playing we usually get to the bubble when everyone still has well over 20 big blinds. I don't know if that's part of the problem. I've been trying to use a push/fold strategy and after a while I usually get trapped by a limper or min raise. Besides that I'm really not sure what range I should be pushing with.
In the last game I played I tried to use raises a 3bets a little more and it seemed to work out for me. For some reason my opponents seem less inclined to call a 3bet for 3/4 of their stack than an all in. I'm not sure why.
Any direction, videos, articles, etc., you can direct me toward would be much appreciated.
