Capped £1/2 table @DTD.
Recently moved to this new table from the £0.5/1. I've been pretty card dead all night and this table is no exception, I've hardly played a hand yet.
Have no real great read on anybody. Only info I have is that villain3 has quite a high 3b% particularly out of the blinds, and has hit flops nearly every time stacking someone with hands such as Ad9d etc. I have no real reads on villain1 + villain2 as of yet, apart from villain 1 calling a few 3b ip and folding post. Do seem pretty fish tho, wanting to see flops.
I get dealt

UTG+1. I raise to £7. (playing £317)
Villain 1 calls from mp1 (£101), villain 2 calls from mp2. (£120)
Villain 3 3b's to £28. (£500+)
Blinds fold.
I flat.
Villains 1+2 also flat.
Flop

(pot £115)
I check. Villains check it round.
Turn

(pot £115)
I check.
Villain1 after thinking about 7secs shoves his last £73.
Villain 2 folds. Villain 3 folds.
Hero?
What I'd like out of this thread are thoughts on my line in this hand, and my thought process.
I flatted the 3b, I did this because villain3 seemed to have quite a wide 3b range, so I planned on using his aggression against him. Also, I felt if I raised to say £75 I would look ultra strong and I would more than likely make worse hands fold and loose value, whereas I had seen the two remaining villains be pretty fishy pre and felt there was a good chance they'd call.
On the flop, I did ponder about shoving and just claiming the decent size pot, but felt I'd be loosing out on some value from one pair hands that the fishy shorties might have hit. I thought of donking 1/2 pot but decided against that as I did not want a decision if the original raiser come over the top of me. I decided to check the flop, hoping I could call off a shorties shove.
Turn card I really don't mind, as I felt one of the shorties would have shoved with a fd or hit a pair otf. I check.
Villain 1 shoves on what I thought was a great card for him to rep with.
I need 39% (73/188) to call?
