$150 4-5 table SNG basically at my local casino.
Starting Stacks of 8k.
Level 5 Blinds 200/400

Utg +1 .... Has been making unusually large raises. Villain has done this at least 4 times without showdown. Villain has 6000 chips total before hands begins.

Hero MP (11k stack) Playing very tight preflop. Made 2 small stabs successfully on flops.

Villain opens for 2400.. There are 5 players remaining to act and he is so short (only has 3600 (9bb) behind), I believe that isolating here is the best move.

I raised to 5k and Villain tank folds.

I obviously took down a decent pot here. Should I have played differently to max value?
