Waaaaay to many hands. LOL If your playing on a heads up table it is feasible. Folding 60% of the time to a 3-bet seems a little high as well don't forget about flatting or 4-bet bluffs. You are in position and if the player 3-betting has a high 3-bet frequency then folding 60% is definitely to high. 40% to 50% with 60% being the max rate (against tight players) would be the way I'd go. As for the BTN opening range, I play a little tighter than 70%-80%, like 30%-35% tighter. LOL A range I most often use is at 47.8% giving me 634 hand combos, more than enough I think. You don't want your range to be to weak because the players in the blinds (if their smart) anticipate open raises from weak ranges. A range of AA-22,AKo-A2o,KQo-K6o,QJo-Q8o,JTo-J8o,T9o-T8o,98o,87o,AKs-A2s,KQs-K2s,QJs-Q7s,JTs-J7s,T9s-T7s,98s-96s,87s-86s,76s-75s,65s-64s,54s-53s,43s-42s,32s (47.8%/634 combos) works quite well for me. I hope this helps. Good Luck at the tables my friend.

This is what my standard opening range from the BTN looks like (approximately). Dark blue ones I'm raise/calling or raise/4betting, and rest I'm raise/folding.

I open approximately 50% of hands, and folding approximately 50% of the time to 3bet. I 4bet AK and JJ+ for value, I 4bet stuff like K2s as a bluff, and middle hands I call.

This seems like a pretty good strategy for me. Feel free to give positive or negative feedback.

And keep in mind that optimal BTN opening range varies a lot based on players on blinds. It's very situational, versus some blinds I open only like 35%, versus some blinds I open 100%.

If you like high variance, do it, but dont expect to win much of it because there can still be a few streets to play and not every hand is won by openraising and c-betting.

thanks a lot guy=)
