Need help understanding this hand, its just fucking weird too me. Day 1 of the 5k at Council Bluff, Jeff Banghart age 35-45 just sat down at my table and knew who I was and all about my sucess online. Now he just won a sick pot against a super aggro player a few orbits ago, And has been very active since has bluff once or twice got caught but for the most part has had a hand when ever he bet. Most importantly we haven't played a hand together and I've been weak tight the whole day I've been playing tighter than the old guys in this tounry.

Blinds at 400/800 w/ 100ante
effective stacks(mine) 38k in the BB w/ 8To

Limped pot 4 way action (pot 4k): SB(Jeff Banghart very active), Me BB 8To
Limper A utg+1 weak tight, limper B super aggro loose aggressive

Flop: Ts7s3h

SB checks
BB(me) leads 1600
Limper A calls
Limper B folds
SB calls

total pot: 8800

Turn: 8c or diamonds cuz i had the 8 of spades in my hand

SB checks
BB(me) leads 3300
Limper A calls
SB check raises to 10k
BB(me) calls
Limper folds

total pot:32,100

River: 2h

SB shoves all-in
BB(me) 23,400 left

What should I do call or fold? What can the SB have here that I can beat? What should I have I done on the turn? (A) lead like I did (B) check call limper B if he bets (C) Shove after getting check raised by SB (D) which is the worst fold the turn after getting check riased
