Here's my 2c and my 1st post on this forum:

I would never reraise flop here. If the board was rainbow, I'd fold 100% of the time, cause draws won't be part of his c/r range.

In this spot I would maybe call his reraise hoping to see a non-spade card on the turn. If he checks missed turn, I'd bomb here. If he bets the turn again, I'd fold easily (and if A or Q comes, it's a really nasty spot imo).

PF he's 20/18 which pretty much means he's calling/limping small PP's PF. Would be nice to know if he generally defends blinds or folds to steals, that would definitely change my flop decision. But without a read, I'd do the above.
