Here are my notes on Derv:

loves suited cards. plays for any flush/straight. will play mid/low pairs to river to chase

bets his draws very hard. Limp calls with any old shit (75% saw flop). Limp called 53s. On OESD board, bet pot then reraised a raise. On turn he pushed. Does shit like this often. Is very aggro and semi-bluffs often.

So, given that, when he bet the pot in the below hand, i figured he didn't have that much, so I push. Didn't think he would call, but he did anyway... too risky a play? maybe reraise to $25?
