I would probably fold but thats just me im pretty weak tight
If you plan on seeing a showdown then this my friend is an outstanding time to raise for a free showdown
What i love about this raise is that:
1. You might possibly have the best hand (maybe more so according to a specific read)
2. You have very few outs so you have an easy fold if it gets 3-bet
3. The board just paired that means he wont dare to 3-bet as long as he doesnt have a 9. So even if he does have a pair he will check it to you on river.
