I'm new to this forum but not to live or online poker. I play live $2/$5 professionally & will be posting hand discussions for feedback.

i hold 88 on the btn facing an open for $20 from utg+2 & 2 callers from middle position; i call & the blinds fold, leaving a pre-flop pot of ~$90~; raiser has $700 behind, covering me, middle 2 callers have less; flop is 994 w/2 hearts; raiser bets $30, table folds & i call; turn is Ax, raiser cks & i ck behind; river is 8h; raiser bets $80 & i tank; i decide he has a 9 or rivered flush so i raise to $225; he thinks for a second and shoves

The original raiser in this hand is somewhat of a lagtard who opens frequently & calls too often with fairly week holdings. He was felted a few orbits earlier in a hand where he ck/called flop & turn then shoved after an over-card rivered.

Thoughts on whether or not I can find a fold here given the information I have?
