As you played older and younger pocket pairs pre-flop.

I wonder how you play pocket pairs pre-flop.

waiting for the answer of professionals

Cash NLHE 6 -max, BSS.
With 22-99 pairs I raise first or call a raise in front of me. If someone then makes a 3 bet, I fold. AA-KK - raise, 3bet, all-in. QQ-TT - always different ways which depend on situation.

I play pocket pairs if it's 22- - 33 - 44 - 55 to 10 I play cautiously when players go at a small bet, if they start raising or reraising, I drop small pocket pairs,-- and pocket pairs JJ-QQ-KK - AA - I play aggressively and look at my position and make a raise or go all-in!
