Stacks involved

MP(fish) $750 V1

CO(hero) $1,300

BTN(reg) $3,000 V2

Mp limps hero raises to $35 with 1010 V2 flats V1 flats

Flop

1088r

V1 checks hero checks V2 checks 

Turn Qd

V1 bets $35 hero flats $35 V2 raises to $135 V1 snap calls, Hero?

V1 is an older man have played with him a ton but he is very spewy, he lost a big pot to V2 an orbit earlier and got stacked by V2 in the beginning of the night, 

V2 is a very tough reg, I also have played with a lot and we always try to outthink each other when we are at the same table, we only have 1 very big pot against each other that happened a long time ago.

How should I continue OTT?

Reg's range is basically capped KQ-AQ maybe a str8 but I doubt the latter one very much, no matter how I play this he will see it for what it is.

When yam yam snaps off the $100 I think I could get stacks in by the river with a turn raise because I think his range is a bunch of 8's( don't think he has the nuts cause he would raise 88 from mid position).

1) do I raise OTT?

2) do I flat keep the reg in? (This option I really don't like cause I will lose value, since he will most likely see through my hand..)

3) if I raise the turn should I bloat the pot to get stacks in OTR?( I lose reg with this option)

4) should I have cbet flop? ( hmmm.... Didn't see much value in doing that)

5) if I raise OTT what is the best sizing?

Ps
