From last nights visit to DTD

1/2nl 9 handed. Game has lots of soft spots at the other end of the table, regularly there is someone all in after flop, preflop has been quite passive unless a couple of the decent TAGGY players to my left have opened. Im stuck about £250 at this point.
Fwiw, villain has been limping quite a bit, ive seen him iso-raise once with an ace vs the fishies, but later on i found out he plays professionally and plays 'some' 2/4nl 3/6nl online (raking $1200 per month if this helps understand his calibre)

Hero UTG £275
Villain BB Covers

Straddled by Hero

Two callers in mp, sb completes, BB completes i look down and check with

Flop is :Qh: (Pot £16)

checked all the way round
Turn is

Fishy kid in sb bets £8, bb calls, i make it £32 straight (very quickly) all fold including SB back to BB.
He asks how much im playing, then makes it £91. Miff
Whats our plan?
(fwiw, as soon as he asked my stack size i knew what was coming and what my decision would be)
