Curious how others make a plan to go after Regs they run into a lot. These two below I see at the tables pretty often and they play drastically different styles:

Reg 1 - Big Winner at these Stakes - Does not seem to get out of line very much and plays pretty solid all around from my experience.
23/18
RFI - Early/MP 21 - CO 19 - BTN - 38
3bet - 9
Fold to 3bet - 50
CB 55-63 (OP/IP)
Fold to Cbet 62 -25 (OP-IP)
Turn Cbet 67/56 (OP/IP)
Fold to Turn Cbet 50
3bet Pot Cbet - 74 (bets 25%ish pot on Flop and usually large on Turn)
Fold to Cbet 3bet Pot - 40

Reg 2 - Comes off like a maniac but tends to be a solid post flop player. Not a world beater at stakes I play but difficult to handle and is a regular at stakes a few levels up as well.
41/31
RFI - Early/MP 23 - CO 37 - BTN -71
3bet - 15
Fold to 3bet - 30
CB 77-81 (OP/IP)
Fold to Cbet 53-46 (OP-IP)
Turn Cbet 54-55 (OP/IP)
Fold to Turn Cbet 50
3bet Pot Cbet - 81 bet sizes vary
Fold to Cbet 3bet Pot - 37
