Yes, I think is quite early despite I don't dislike your move. 150 hands is not a representative sample to deduct about his 4betting range. If you know he is 4betting you a lot, A♦:4♦: is not a good hand to 3bet him. I prefer a stronger range to do that like 99+, KQs, AJs+, AQo+

This is a good example how wrongly used stats will lose you money. 150 hands is way too small sample.. The guy has 4bet you twice, you can't go crazy because of that

Even if his 4b range is big, you cannot push here.
Your 3b is as a bluff and when facing a raise you should fullfill your plan and fold.
Another question is why do you bluff 3b a gut that 4b much....
And the sample is too small....

All you know for certain after 150 hands is that he is loose and aggressive preflop. (Hell, who isn't:f_biggrin:)

There are better ways to take their money if you think they are bad and have weak ranges. Just call or raise small (so that they might also call, not reraise/fold). Then you play IP versus weak player with weak range. It is much more profitable versus bad players than to try to steal the few crumbs already in the pot (and get sucked in into a silly preflop raising war).

I agree with everyone above.

Your adjustment vs a guy that 4bets a lot is to 3bet tighter so that you can call his 4bet more often. You don't start to 5 bet any hand with an A or other weak hands.
