[Roland]

I would like the LRR better if your suit was live (this would be consistent with you tendency to LRR with 3-flushes). Since your suit is kinda dead here, your hand is absolutely obvious, and that’s bad.

I wouldn’t 3-bet on 4th, but that’s just me.

I can’t see folding on 5th. After limp-re-raising 3rd and 3-betting 4th, the pot is just to big to fold.
Check-calling is my default play here. He will almost always bet, planning to take the free card on 6th if he doesn’t improve.

The real question is, then: Do you bet 6th?
