He raises 23% of his hands preflop. c/f flop seems super weak.

Edit (though by stoving I'm not ahead by that much):

Board: Js 2c 9c
equity win tie pots won pots tied
Hand 0: 56.383% 55.16% 01.22% 129608 2868.50 { Ks9s }
Hand 1: 43.617% 42.40% 01.22% 99615 2868.50 { 66+, A3s+, K7s+, Q8s+, J9s+, T9s, A8o+, K9o+, QTo+, JTo }


Assuming he continues firing with all hands (unreasonable) by the turn:

Board: Js 2c 9c 5s
equity win tie pots won pots tied
Hand 0: 67.281% 66.38% 00.90% 6903 93.33 { Ks9s }
Hand 1: 32.719% 31.82% 00.90% 3309 93.33 { 66+, A3s+, K7s+, Q8s+, J9s+, T9s, A8o+, K9o+, QTo+, JTo }

That assumes he's positionally unaware and that he'd pick a sane 23% range (probably I do better against the actual range he picks).
