Day 2 of the WSOP ME, 400/800/100a.
I had just been moved to the table less than 1 hour ago, nobody had busted yet or played a big pot and the table was significantly tougher than usual for the main. All stacks were deep (I might have been the short stack, if not def 2nd shortest). There were was no obvious fish at the table, almost all under 30, no raises >2.5x, no limps, standard amount of 3betting, etc. The 4 spots to my left were all <30, all 70bbs+. Also, the table was not due to break any time soon, possibly the rest of the day (2 more levels after 4/8).
Villain: a tourney reg, 25-29 years old, hasn't done anything worth mentioning or been overly active or passive, has about 70-80k. BTN has 200k+ and is a young tourney reg, got moved to the table <30 mins prior to the hand, and has splashed around a bit as you'd expect. My image: mid 20s reg, hadn't played many hands, came to the table with ~35k and have about that to start the hand.
Villain opens MP (UTG+3) to 16 or 1700, BTN flats, i call in the BB.
I check, villain bets ~3k, BTN with 200k+ flats, I flat.
I check and as soon as I do Villain asks to see my stack, I oblige (have ~30k), he bets 9100, BTN snappy snap folds, back to me.
Obviously my range is super capped.. and my exact hand should be fairly obv also.
Am I wrong for being extremely suspicious of villain betting this turn with BTN behind him? Especially given that the natural inclinations of tourney regulars these days in tough spots is so heavily defaulted to pot control.
