-722BBs over ~90k hands(LC)

[blackize]

He isn't running badly. He is putting in too many bets when he is behind and/or not enough when he is ahead. 34% WTSD and 54% W$aSD tell me that he is winning his fair share of hands, but he takes his losers too far and doesn't make up enough from his winners.

My suggestion is to drop down a level and work on value betting more and his hand reading skills. With his aggression numbers he is likely betting, raising, checkraising, and 3 betting too much on the flop and the turn in bad situations(or good situations that then go bad).
